So now i have my empty chip but still the same fault. Only the PCH shows some heat up to 30c. Pressing the power button doesn't change anything. So 19V and 0,05A.
Is there any way to measure if the PCH is dead or anything else?

Could you post a Screenshot or name of the programmer? Cant open the link because of my region....

So you know any other source? I know a shop in Germany but he showed a YouTube video where i replaced the chip and told that it doesn't need programming. But he sells "programmed" chips for 44 Euro....

Ah okay, got it. Do you know a trustworthy source where i can buy a new chip?...

No need for programming on this model. You can find a thread at badcaps which confirms it and there are several videos....

Hi Buddy,

did you solve your problem? Same situation here. I ordered a EC replacement from AliExpress and now stuck at 19v and 0,05a....

Hi all,

i got this laptop from a repairshop which tried to fix a non booting bios issue but only physically destroyed the mainbios chip. I reprogrammed the bios and also the i2c and EC chip several times but the fault is still the same. I get power LED for 3-5 secs. and the laptop turns off. Charging also works.
Concerning the flashing i don`t know what else to do so i looked for other problems.
My thermal cam shows that the SY8288RAC power ic at PU1801 is the only hotspot (35-40c) when the board is off with battery connected. Adding the power supply i get a cheeping noise...
