ThinkPad P15s Gen 1, NM-C931 REV 1.0 touch screen replaced only works in UEFI menu
original screen was BOE NV156FHM-T07 with On-Cell Touch screen I²C
replaced with what was in my stock, which is IVO R156NWF7 R2 which is also with On-Cell Touch screen I²C
now touch screen works perfectly in UEFI BIOS menu & boot menu. but not working in OS, tried windows & linux too
with original broken screen i can see in device manager touch screen in human interfaces
but with the new screen it's not showing in device manager
is it lenovo blocking it? is it driver missing?
I²C is a headache

Re: HP ENVY - 13-aq 18744-1 burnt ic 3G=S3F
I replaced it with another one and same happens. I noticed that 3.3v is measured 3.5V which is higher than normal. maybe that's why it shuts down after a minute?

Re: HP ENVY - 13-aq 18744-1 burnt ic 3G=S3F
When laptop is on these are the Voltages I get on this IC
the laptop turns off after few minutes & this ic gets hot, if i take the ic out the laptop turns on but no POST
it looks like it outputs 1.8v but the i think it shouldn't gets so hot like that...

Re: WHEA_UNCORRECTABLE_ERROR - Dell Inspiron 1559
I was also facing this error on a toshiba laptop i5 4th or 5th Gen CPU, can't remember.
I tried few things like you did. I also tried flashing the bios from toshiba website. all ended with same BSOD WHEA error.
tried reflowing the CPU too, but same BSOD error
I gave up on it, thinking the CPU is BAD internally
didn't tried reballing the CPU, maybe that will do.

Re: Surface Pro 4 Dump fix!
i have the very same problem with 2 surfaces. the board p/n x911788-009
i tried a lot of bios dump from different websites, some doesn't gives display. and some gives display,but only stays at surface logo. i tried to clear ME region, changed ME versions. all gives the same results. i think it's not only the bios that got corrupted during the surface firmware update. i think there are more firmwares that got corrupted. i have found an eeprom near the EC chip which is programmable, I have found any dump for it now where.
