Yay!! Great! I tried this, and it didn't show the Dell logo immediately, but after a few seconds it did. Thank you a lot.

Though it didn't work at first, but I was able to discover that the issue is with the RAM.

Thank you sir it really worked

[@danishzafar8630]

Thanks dear. Fixed. Can you mention the reason of this issue as well?
By the way dell logo didn't appear immediately but after sometime it did and reboot followed by time/date setting in bios and it was solved.

[@umarfarooq805]

I think the actual issue is due to bad cmos battery. Replacing this cell will permanently resolve the issue.

[@umarfarooq805]

I have tried my above solution but issue persists. Technician says its bios is corrupted. Please guide is he right or what is exact issue.
