Re: Acer 5755g motherboard / CPU issue.

I measured the resistance is 0. Today volts are 2 recieving , 0 output.

Re: Acer 5755g motherboard / CPU issue.

If i checked the correct, 18.67 recieving upper side, 0 output down side.
You are a big help friend.
Could something else be broken too?

Also , is the resistor completely broken? Cause the laptop tries to POST sometimes.. maybe the resistor doesn't make a solid contact or something?

Thanks for your help and the quick replies.

U22 Pins 1-2-3 recieve 2.30 volts.

Pins 5-6-7-8 recieve 5 volts.

Re: Acer 5755g motherboard / CPU issue.

Sorry but I am kind of new when it comes to the motherboard.
Are these , PL20 and PL21? Or if you can link me a pictured to recognize so I can recognize them by eye?

Hello everyone.
I have an acer 5755g that was working fine up until yesterday morning. I tried to boot it, and a strange noise came from the speaker. Like a single beep, but distorted ( removing both ram's doesn't make any sound) . Everytime I tried to boot it, the same thing happened. I dissasembled everything. Now there's only cpu , cpu fan, internal gpu and the nvidia one.
Before that problem occured , if I tried to boot the laptop like this, it tries to POST ( fan starts spining and stops after 2 seconds cause there is no ram ).
Booting the computer results after the problem...
