UPDATE: I have tried cleaning the sensors and edges, nothing. I have also tried Ubuntu 24.04 on a USB stick and nothing.
Then it might be a dead as dodo. And might be the reason it was tossed to bin.
Did you run lspci to see if the touchscreen device shows up? Might be disabled in bios.
@@mikebarushok5361I'm not sure if it would show up as a pci device - HID are usually connected via usb or ps/2 - so it would rather show up on a lsusb
as for disabled it bios: although possible I don't think that's the issue here - the device is marketed as touch device so the default is likely to be enabled so even in the event of a bios failure it would default to be enabled - if there even is an option to disable it
the fact someone took the effort to wipe the drive shows that someone had a play with it - so we assume it's a hardware fault
@@cryptearth they might show up as anything - depends on what the uefi and hardware teams did.
Wacom digitizers have some quite exotic versions with i2c interfaces for example.
Hidden Settings can be changed quite easily (they will reset tho when you reset all) but i highly doubt that someone joinked the flash out, modified it and bypassed the rsa signature check to turn it off by default :D
2:47 sticker says it all; "OS Win 8.1 Pro Downgraded to Win 7 Pro" - it is delivered with Windows 7 Pro installed, that was a thing back when 8/8.1 was a dumpsterfire and companies buying machines required 8/8.1 computers to be delivered with Windows 7 installed.
Also the tease of him having device manager open but not expanding either pointing devices or HID devices. Not happy Jan!
It was the same with Windows Vista 🙂
All the time when we bought Windows Vista capable machines we had them downgraded (by DELL) to Windows XP, or installed XP ourselves.
These machines would still have the Windows Vista sticker, but they never ran that abomination of an OS.
Came to say just that
@@Rob2 Except that Vista was fine after it got updates, maybe for people that were heavily into games or something had problems, but I had no problems. I barely noticed any difference when updating to Win7, except that Vista was prettier.
Yep! Windows 8 was, according to news articles I read, intended to be a complete rethink of Windows, but once it got released and people who weren't tech enthusiasts started using it preloaded on new PCs, they didn't like it, often because the UX was biased more towards touch input but a lot of PCs were still being built without touch and/or users were still accustomed to using a mouse and keyboard. The shut down option being hidden led Acer to develop and preload their own "Acer Power Button" utility.
On top of that, Windows 7 was released just a few years prior in 2010 and lots of companies were still running Windows 7 Enterprise from when they would've upgraded in around 2011-2012, only upgrading to Windows 10 in around 2016-2018 depending on accounting cycles.
When hard drives show up as SCSI it's almost always a regular hard drive that is set to RAID mode in the BIOS.
Or AHCI.
2:42 Notice the small print on the label: "Win 8.1 Pro downgraded to Win 7 pro"
Personally I would call that an upgrade...
Well Eternal Blue backdoor is less so an upgrade, but certainly 8 was terrible.
Even Windows ME was better than the launch version of Windows 8.
@@marijnl hey i am offended. i loved WinMe
@@H1pok0ndr1ak and I'm one of the eleven people who enjoyed windows vista. lol
We, for some weird reason, often received requests to disable the thing by any means necessary by larger companies or government users.
Be it by physically disconnecting things internally or doing it in bios. Think it had to do with the additional burden on cleaning personell but I don't understand how. Just let the users clean their damn computer screens instead. Guess stupid is universal so you may wanna look into that.
Yeah, will check the bios.
I remember fixing/upgrading a couple of very similar HP machines at work years ago.
The hard drive caddy is so complicated because the chassis is originally designed for 3.5" drives. I don't know why HP decided to put a slower 2.5" drive in this unit, or why they made that SATA extender board instead of just mounting the 2.5" drive in the corner of the caddy so it plugs into the existing connector.
Most likely it isn't upgradable to an i7, as the motherboard won't accept any CPU with a TDP higher than 35W (so 4770 and 4770T are both out), and the BIOS doesn't support later Haswell Refresh chips.
Why does Dave have the world's best dumpster to pick in? It really makes me want to move from America to Australia and maybe one day meet Dave.
Hahaha yeah. If only it was easy as that...bearing in mind oz land is almost as big as USA lol
dude. try going to a college as soon as the students leave. especially if you can find where the foreign exchange kids are at.
ive never ever paid for a computer. i cant... im a contractor so i dont need performance and i keep finding two year old models that just boot up.... its insane. i give away at least four computers a year.
I find similar things here in Mexico.
@13:50 looks like that was designed to either use a 3.5in drive or the installed 2.5in drive with that adapter cage.
probably serial port so that it can be used in an older POS system
Regarding the touch screen not working: We used to turn off the touch screen in the BIOS so when people pointed at the screen they didn't accidentally click anything. Might check the BIOS for disabled touch interface.
I got 2 of these when a local florist went out of business. They used it as a point of sale machine tied into their inventory/reorder program. Too bad the upgrade to Win 10 deleted the drivers for the touchscreen. I installed an SSD last night in fact, runs like a scalded dog now. I use it for a surveillance system remote monitor. Hooks up to 5G Wi-Fi and everything. I do wish I had the touchscreen tho.
boot a linux live. touch will probably work. and you can do a lspci and google the device to find better drivers. or check additional drivers in windows update. I remember working on one of these a few years back. seem to recall the driver being a pain. had to be installed in the correct order with the video and chipset
Cool, I have something similar, HP media pc, all in one, now i just have to boot it. Christmas present, many Christmas trees have since passed thru. Working fine when i parked it. A heavy tank just like yours.
Im glad someone likes the all in ones. Nice score Dave.
That hard drive location is designed for a 3.5" drive, the caddy is to adapt to 2.5"
Win10 will run perfectly fine on a Core2 Duo believe it or not
honestly that machines still servicable with a few upgrades
A 4th gen i5 and 12 GB of RAM is totally usable nowadays. Sure you can't use it to for gaming at the highest graphics settings, but for all other applications it's more than enough. Good find!
this looks like one of those cashiers pc that would connect to the register , maybe that explains the serial port and the touch screen
4:06 That somebody was HP themselves. Check 2:46. The sticker says "OS Win 8.1 Pro downgraded to WIn 7 Pro" :)
They made the right choice!
If you don't want Linux on those devices, the best option is Windows 10 IoT Enterprise ... and activate it with Massgrave to get the Updates until 2031. I know it's piracy, but in this case it's ethically justifiable to literally avoid the devices going to landfill.
you have to enable "pen and touch support" in system options to get the touchscreen to work
Supporting Win8 means it was supposed to be a 10-point capacitive touch, not the 2-point IR touch that was supported in Win7. I'm surprised that the 'downgrade to Win7' was allowed to stick with the IR.
For the IR, the left/right/bottom edges are retroreflectors. The IR emitters & sensors are in the corners. The middle emitter/sensor is the 'vote' when there is ambiguity.
All my best PCs and or Systems have came from the dumpster at work. I really love finding dozens of the HP EliteDesk Minis. G1-G8. All of them have 8 gig DDR4 and an Nvme 256 SSD. Just thrown away, I'm restarting my collection of NEC P4xx systems for a complete display wall for the everyday low low price of A few cables, and a little work, outside of work hours. 😂😆 It amazes me how much potential money just mixed with the rubbish.
The HDD mechanism looks to be over engineered, because it's made to support 2.5" and 3.5" drives.
Plug it in like Flynn
I'm fed up with this. - Our 'dumpsters' around here have broken chairs and dead cats in them. No electronics EVER.
Nice score! An older PC but still decent for many tasks, especially with an SSD upgrade.
nice find
The best Dumpster in Sydney strikes again !!! LoL
That said i hate these all in one PC's, dumb power supplies, zero upgrade slots...but FREE !
I actually like them, very convenient form factor, no desk space for keyboard+mouse if you use the touchscreen. Not for everyone, but they have their place. I bet the serial port was asked for by a major customer like a bank or some such.
@@EEVblog We bought "thin client" devices from HP in that timeframe and they had all the types of ports you can imagine, and never use.
2 serial, one centronics parallel, PS/2 mouse and keyboard, and then of course USB. And they came with USB mouse and keyboard.
Indeed there probably is a market for such things where they have unusual peripherals and need to be prepared for everything.
@@EEVblog Or they had older thermal printers at some point that were serial only, or had older POS card terminals that all were serial port connected, before these all went to USB interface, and moved the serial interface chip to a daughter board on the machine. Plus older point of sale displays work with serial port only.
@@EEVblog I understand the appeal. But the lack of repairability and modularity is the major issue for me.
If a PC component fails, you've also lost your monitor. Whereas with a desktop you can at least salvage the screen and usually replace something. It's great that it has RAM shots though 👍
Haswell was the first generation with NVME, so maybe even a PCIE SSD is a go. Perfectly fine machine for Win10 or Linux and office. The RAM situation needs fixing for another performance boost too.
I have an even older all in one PC that I just used to set up Batocera. Very cheap retro games machine.
There is no Unknown devices in Device Manager, so I don't think it is a driver issue for the touchscreen. It is not even detected. Either it needs to be enable in the BIOS or hardware problem. You can try turning the lights off and point your digital camera to those sensors and see if they are alive.
There is a serial connector on the back of this huge microcontroller, so you could flash your own program. ;-D
OOOH! how lucky to find computers like this, I love how you say "It´s kind of old" my computer is an AMD Phenom X2 black edition with 8GB RAM, A3 asus board, running W10 22H2 and its my every day, all day PC 😵💫
Check BIOS F10 on HP Logo. There may be an option to disable or enable the touch screen. If my suggestion works. Can I have a Chicken Dinner?
The sticker on the back says "Win 8.1 downgraded to Win 7". So it is the factory OS.
The touchscreen also may not work without the HP Service Pack or whatever they call it. The files may have been nuked during the data deletion.
If "Joshua" doesn't work, try "overgrown pile of microchips" or "silicon diode" 😉
the screen looks decent
Why is there such a big black border? It's like the old days on CRTs where you avoided going to the edges due to distortion.
Still useful for web browsing and daily work, not for gaming of course.
would do finely for a bunch of uses. with touchscreen would make a nice control screen for bunch of stuff.
Could be worth a try to check if the original hard disk has a recovery partition. Maybe you can find the right drivers for the touch functionality there.
2:11 Yes mine have the BLUE colored USB indicating the high speed USB.
I guess that HDD carriage is an adapter to support 2.5" HDDs looks like a 3.5" one would fit there directly
Serial port and DP, probably really useful if used as a POS Terminal
Great find! It’s too bad that Windows 11 is going to make so many PCs obsolete.
If you plan on using the touchscreen, you might want to try and find the original Windows 8.1 restore disk. It was designed for touchscreen computers, that's why everybody hated it. If not, Windows 10 might be a better choice.
given it has a touch screen (that might be workable) and a COM port (serial DB9) maybe you can use it to access test gears com ports...maybe have a "push to test" button on the screen that makes a bench supply do smth...
There's no chance that's a SCSI disk. It's plugged into some kind of off-brand SATA controller that presents itself to Windows as a SCSI interface, hence windows labels it as a SCSI drive.
I remember having to refurbish these at my 9-5 years ago. I thought they were halfway decent for what they were at the time. I’m still looking to find one but the asking price is still too high. Wish I could find one for free!
These All-in-one are dirt cheap atm, I bought 2 Dell Wyse for just some bucks and use them as display for schematics and youtube.. Running fine with Ubuntu, SuSE Linux or even Android x86 / Google ChromeOS.
you legitimise something invaluable to people who love to learn about electronics. dumpster diving Dave strikes again (right through my cold dead heart)
Bet that tilt stand can be folded all the way back, so it can lay almost flatt on the table.
So you can scetch and draw and "be creative" on it.
Btw, have you checked for IR light from the 4 emitters?
oh shoot thats a good call. occams razor
bcdedit /set testsigning off in command prompt to check if driver signing is the issue for touch screen driver
u can in fact install win11(bypassed)
Dave it's a HP Leave it in the Dumpster mate
I installed windows 11 on a free system with an i3 4100 😂 runs streams at 1080 / 60fps perfect for media consumption.
Maybe the touch does not work simply because someone has switched it off in the BIOS?
Checked, nope, no option for that.
Wow, I just trash picked almost the same one except its not touch screen. Unfortunately, i cant get in dje to the PW. Is there any way to bypass it? Or is it junk now?
When all the companies were going bust and liquidating a few years ago, I was going around industrial estates and looting the bins. Found one with hundreds of Lenovo tablets in them and made £25K on them.... No wonder why these companies all lose so much money and cost the tax payer. I still have about 4000 Siemens motors that sell for £600 odd each when new, but they were all used... but still work fine. Sadly I haven't got shot of them yet as they're a niche sell. Frigging one company threw away so many CCTV cameras as well, the 360 ones and they were all brand new. I want another lockdown so I can go looting again lol.
Is the touchscreen controlled by / turned off in BIOS?
Check the sn, swap in an SSD, clean install Win10 to make it more useful.
he did, if you bothered to watch the video you would know that
Install Linux on it. Install Linux on it.
Dave, will you do a debunk video on Embr Wave wearables, it seems to me a TEC peltier module that's app controllable over bluetooth from phone
they even have subscription plans to ripoff people
Touch screen might be disabled in the bios.
I have noticed Win10 won't load some drivers unless it's licenced, but then again that hasn't been connected to the internet so it can't know. Either way you can get a Win10 licence for $20 if you watch the start of a Tech YES City vid, ie, it has the ad, and I've bought 2 off.
Checked, no option to disable it in BIOS
Nice slot machine emulator you got there, if the touchscreen was working 😢
Yeey, dumpster diving
Did Davey forget how to film horizontally? Lol
w8 has touchscreen support build-in. w7 doesn't.
With the amount of good stuff that you find I think you should get a shipping container or buy an old warehouse and start storing everything even stuff that’s not USB three with the way things are going today you don’t know how long you got tell company start taking back electronics and you don’t really own it they’re basically doing that with the recycle programs think about it how much useful technology gets thrown away every day I would love to have a laptop right now a desktop computer i’m on an iPad that I’ve have to upgrade soon so I can keep watching CZcams As sander cage would say it’s all the education we got
I would like to find such items in the basket
11:22 Excuse me? 😂
If you can find a pair of matched DDR3 1600Mhz SODIMM sticks you'd get a relatively cheap but substantial performance boost as the RAM would be able to operate in dual channel mode, the current mismatched sticks [4GB+8GB] will prohibit the system from being able to leverage DDR's dual channel mode.
For the touchscreen HID driver you might have to manually install/update the "HP Touch Screen Filter Driver" driver in Windows device manager, at some point HP's Windows driver signing certificate changed and they never recompiled/re-signed their older driver releases, therefore Windows 10 will not automatically use the signed [with an invalidated certificate] driver by default without a bit of jiggerypokery.
Aside from that it's a good find that could be put to multiple uses of which I'm sure you've already got something planned for it.
I found an 8GB 1300MHz stick. Not matched, but I've got 16GB now.
From the tests I've run myself I never got a substantial performance boost from dual-channel mode. I got at most 3-4% percent boost. Maybe some specialized workloads could benefit more but browsing, office work or even gaming did not yield a visible performance difference. Likewise, memory speed differences were not translated into expected performance boost. I came to the conclusion that the only performance trick regarding RAM which actually delivers visible performance improvement is to have as much memory as possible. Only that.
@@georgedone7997 "Browsing, office work and gaming" are relatively light loads with the latter relying on a GPU and its own VRAM far more than system memory, those tasks generally do not use a lot of system ram capacity compared to say using a cpu for graphical/3D rendering or tasks where you are using the majority of your memory capacity such as large GIS data & image sets.
In the cases I mentioned dual-channel mode in DDR makes a huge difference when lots of load/store cycles are happening between the CPU, it's memory controllers and the RAM, there is also the reduced latencies with dual-channel vs single channel which you may notice in day to day tasks with the PC reacting more "snappy" depending on overall system loads involved.
@@EEVblog If you are able set both sticks to the same timings/frequencies in the BIOS** there's a chance dual-channel will become enabled, if that doesnt work at least you've got matched capacities.
**OEM's usually gimp their BIOS options so your mileage may vary on that.
@@georgedone7997 I also haven't found any notable performance boost going from single to dual channel for compute tasks. However when you are using the iGPU it does help, I think usually around a 30% improvement.
I fail to see the problem with advising to install Linux on this.
He's not fat or stinky enough to install linux LOL
@@TextileGeorge And yet he tried Ubuntu since then.
Nice AIO, I'd keep it. Pretty modern and really well built. To be honest, it's the same generation as my main PC after a recent upgrade; I got a hand-me-down semi-discombobulated PC from our tech uni's robotic association. i7-4790 on a GA-Z97X-UD5H mobo, better than my i7-2600k on a GA-P67A-UD5L. It may not be faster, but is way more stable.
As for the HDD, it may be for storage while the system may be installed on a M.2 SSD on the mobo. I'd be very surprised if the old mechanical disk was used for the OS.
Joshua... classic, but I thought you could only pull it off on an IMSAI.
Speaking of your Comically Long Screwdriver, it reminds me of how I had to fix a pair of Samson db500a stage monitors with holes so deep I had to use a makeshift screwdriver out of a M8 threaded rod and a spare hex bit extender. Good enough for reaching the screws WaaaaaaaaaaaaayDownInsiiiiiiiiiiide and certainly longer than yours, haha!
Give that fan a BJ, post a video on OnlyFans.
OS was on the HD.
@@EEVblog now I'm surprised anyone would still do it ten years ago. That's just bovine excrement.
@@KeritechElectronics I helped my friend upgrade her laptop around then and I remember SSDs being quite expensive. I have an old store mailer from late 2013 and about 90% of the new systems were HDD only. It's perfectly fine for a lower-end desktop from 2014-2016.
It could sign in to the neighbours wifi network...ghehehe ip scan.....
Windows 10 will work but may be slower than Win 7.
Did you ever find a Wyse (Dell) PC?
Have you checked the BIOS for touch screen? Maybe someone disabled it.
he did
Hands up all those that like fingerprints all over their screen V those that like a clean screen with mouse and keyboard !
I have a few clients that have a lot of AiOs, all really good spec and none that can be upgraded to W11. Such a waste.
Any computer with Windows is a waste anyway.

That serial port is so odd on a newish PC, probably some public service counter PC, like Disservice NSW, with some serial gadget on it.
HP PC's have had ancient ports like serial, parallel, PS/2 mouse and keyboard for a long time after everyone else had abandoned them.
Quite likely.
As mentioned in comments, serial port is useful on POS machines, shipping machines, etc. for old stuff like barcode scanners, weight scales. We have some modern units with 2+ serial ports.
Wow Dave's impression of a commenter was spot on. I thought for a second he was playing a recording of an actual commenter.
If my I5 2410m laptop can run windows 11, so can that thing.
Perhaps you should try booting Linux on it to see whether the touch screen is actually broken. A lot of time Linux already has a driver for such things and it works out of the box
True. Even though he said he didn’t want to install Linux, you could just install it to find out if the touchscreen not working is a driver issue, then reinstall windows and work out the driver issue.
He tried, didnt work.
12gig is enough for Australia,.... Explain
Different countries require different amounts of RAM.
Just did my taxes online here in Belgium and needed a minimum of 16gig.
12gig is NOT enough for Belgium
☝ It's true, so true. 👐 Believe me. 🪗
Specs should be enough for cat videos.
10:26 Ackchyually...
Better if the touch screen don't work. Greasy mit prints everywhere, yuck.
Regarding the computer records. What happens is, somebody owes money. A crew comes in and seizes property such as furniture, desks, water cooler, and computers. Then they auction it off. These are untrained people that have no idea of what is on the computer or how to process it. So a computer with confidential data gets sold to a random guy.
By now I think that most business folk even without training know that computers store data.
why no linux 🥺👉👈
Stealing and hacking in one go
Nice ! Can I ask you your opinion sir ? I have a muscle foot scooter I built. It is 40kw . 86v 24s 100v top charge with JK bms . They can shut off the discharge, and charge options . It has 2 separate 40ah batteries that are redundant set ups . I like to recharge them at 3 amps each . I only have one charger that can do 9amp variable. I would like to charge them both at the same time using a splitter on the same charger. They don't always have the same voltage. Can you think of any down sides to this idea? Will it harm anything? Thank you for all you do!
