Hi Guys,
Hoping someone may be of guidance as I slowly start my journey into chip level motherboard repair.
I have an Aspire 7750G that is completely dead. When you plug this laptop in nothing at all happens. No lights, nothing. It does appear though that liquid may have been spilled on the machine (could have been one of the friends but no one is owing up to it) as the keyboard is sticky. Also when I removed the keyboard it certainly looked like a small amount of liquidy substance was apparent. When looking at the motherboard though, I could not see anything untoward.
All I have done so far is watch a couple of vids on You Tube about chip level repair and I was watching this one in particular, http://www.youtube.com/watch?v=goFnh...4&feature=plcp. Anyway, I was able to follow it for step 1, the checking of the VREG3 and VREG5. Both were showing voltages as expected. I could not follow the next step which involves checking voltages at the BIOS chip as I could not find it on the schematic https://cdn.badcaps-static.com/pdfs/...f08a1d1a76.pdf.
Any help and guidance would be super appreciated :-)
