[BillyCZ]

Hello,

I have 3 years old lenovo E320 Edge and I just wanted to clean fan, so i disasemble my laptop, clean it, but when I finished and I complete it all, it doesnt work... It turns on for 1 sec and imidiatly turn off, the red diod is lighting for 1 second too and the fan is runing and HDD make sound like starting (everything only for 1 sec, then is over a I have to turn it on and it makes the same).

Do you have any idea please? I am quite sure that I pluged all conectors and all screws back, I tried to disassemble and completed it three times and check everything.

I tried to change HDD and RAM memory and nothings happens.

Thank you for any advice!

Hi BillyCZ,

Welcome to Lenovo Community!

As per the query we understood that you are facing the issue with No POST on your ThinkPad E320.

• Have you checked with performing power drain option?
• Have you checked with removing the CMOS battery?
• To perform power drain option remove battery and AC power adapter from the system, press and hold the power button for 20 seconds, continue this process for 2 to 3 times and after that connect only power adapter and try switching ON the system.

Hope this helps.

Best regards,
