HDD working fine but still laptop won't boot!

11 posts · originally from https://geek.digit.in/community/threads/hdd-working-fine-but-still-laptop-wont-boot.184708/

I have Lenovo E49 and it suddenly stopped working. It just won't boot, when I press the power button, screen is blank and the fan starts rotating at it's maximum speed. Took out RAM and reinserted, no help. Tested the HDD on desktop, it's working fine. What possibly may be the reason? Help please.

EDIT: Checked RAM too, RAM is working on my friend's laptop, now what's the problem? Any idea?

does the fan keep rotating until you turn off ?
or does it stop after some time ?

and what about other indicator lights ?

Fan keeps on rotating endlessly (though I haven't checked this for long) until I turn the system off and other light indicators just doesn't glow.

Can you enter BIOS?

No, screen also doesn't show up. I switch it ON and fan starts rotating, that's it.

check if the computer is booting completely.
u can do it by waiting the windows startup sound. if its booting then its a display related problem.

It just doesn't boot, no sound, nothing...

it might be an issue with the motherboard (capacitors)

I guess it's a display related problem with the motherboard

check the display with some other PC.
, any beeps ?

Display checked on my desktop, nothing comes up on the screen.
