Hi, thanks again.

Yeah I understand what you mean, without an oscilloscope it's basically speculation at this point.
I'll see if I can gain access to one, but it might not be in the short term. I did remove and replace all of the filtering capacitors you've mentioned originally, since as I would do rework around the area, they would sequentially fail to short so I decided to replace them all.
I'll check the PTR across the board and let you know if I find any issues, but I did buzz out all resistors, capacitors and thermistors that are related to VCCGT drive & feedback...

Hi,

I made a post here https://www.badcaps.net/forum/troubl...-damage-repair discussing my attempts at repairing a water damaged G15 G532LWS computer. I'm currently at the stage where I believe the CPU core may have internal damage which causes any OS boot to fail except memtest86. I own another desktop computer which has similar behaviour with a dead core that causes boot freezes or bluescreens. I managed to fix that system by disabling...

VCCCore seems ok, I replaced the 5030SG mosfets again and also tested each one individually by isolating the coils and powering up. Also tested different NCP81266 and NCP 81210 with no change in behaviour. Regarding the 1ohm resistor PR9422 it reads nominal so no issue with that. I can't seem to boot MATS or truthfully any other live disk OS apart from memtest86. I think honestly the CPU might be bad and maybe I've killed it somewhere along the way of diagnostics. I did inject 0.9v into the VCCCcore rail but that's within the intel specifications. Temperature was ok, the memtest took maybe 2 hours...

Here's the photos of the laptop posting and running memtest86 successfully, but no boot with windows 10,11, installers and ubuntu. I know for desktop motherboards they can let you disable specific CPU cores in the BIOS, does laptops have the same ability if it were to be unlocked?...

Hi thanks for the advice.I replaced PU8106 and additionally replaced PU8001 NCP81266 and spent some time desoldering and measuring all the resistors and capacitors related to VCCGT. The driver of VCCGT had 5V VCC, BST and enable but the PWM pin was reading 1.81V whereas all the other VCORE was around 0.21V. I pretty much gave up and reassembled the laptop and somewhere in the process the laptop now turns on to bios! It even let me read from USB and update it to version 314.
However I think there is still an issue with the laptop as it cannot boot into windows or linux. It just freezes before...

Hi,

I have a laptop an G512LW-AZ003T serial number LANRKD004568428 with what I presume is a i7-10750h and a RTX 2070 with the motherboard code G532LWS.
I bought this laptop secondhand so I don't know much about it's history but I'm certain it's had soft drink spilled into the vent area above/behind the screen.
I'm not a repair professional so I'm merely attempting this as a hobby but I'm seeking advice since i'm a little stumped at this current point in time.
The laptop was in very rough condition and I'm certain it was abused so here was what was wrong with it:
