Hi all, I have dug this laptop out of storage,it refused to switch on.After getting out of storage i tried to power on again with DC adaptor,power light came on and battery charge light to but no system boot, fan etc and after about 1 minute everything went dead,and since not able to get power again.
Took out the motherboard and have 19v on DC connection and i could hear a faint clicking noise. I have 19v upto mosfet Q504 on the schematic. Then 19v on 4 of the pins and 35v on other 4 pins. From there on R523,C522,C528 and C529 where I stopped testing i had 35v. I'm guessing 34v is to high here but not sure how to read schematic to tell me what voltage I should have on these components.
Any help appreciated thanks.
