Re: hp 15 G3 auto turnon after shutdown
Try removing one by one
01.Wifi card
02.Desoldering Lan chip
03.Desoldering Audio chip
04.Desoldering card reader.
If all these steps dont help, replace 3V/5V dc-dc converter. Its coz of PCI_Wake signal not de asserted after shutdown.

I have two such machines which is having this issue. After shutdown the system starts on its own in a minute. It does not start immediately. It takes around 20-40 seconds before it starts again on its own. This is driving me crazy and not sure where to start ..
Some very important points :
- Laptop does not auto starts after shutdown if adapter is connected.
- It will only auto start after shutdown if the laptop is in BATTERY only mode.
- I have tried replacing batteries with a known
- if I shutdown the laptop with adapter connected and lets say remove the adapter after 5-10

I received the PSU today. A quick check revealed a shorted 12V output rail, which is caused by a half dead dual Schottky rectifier. I replaced it, and was able to turn on the PSU but very briefly for a few seconds before the protection kicks in and shut it off.
I'm not sure what is wrong.
All output rails seem ok, with 3.3V maybe a bit higher at 3.6V
Interesting to note, my light bulb is shining brightly while the PSU is running, like there is a short, instead of blinking rapidly as usual when there is an active PFC circuit involved.

Processor i5 8265U
AFAIK schematics or boardview are not available for this MB, but I used a similar board as a reference (G7AL-2G)
Laptop came in not booting with caps lock blinking 3 fast- 2 slow indicating RAM error. Charging works fine. Found bad soldering on the only ram socket present (2 outer left pins and 2 outer right pins).
Once soldered the laptop started fine and I was able to install Windows 11, upgrade BIOS to version F30 from Windows without a problem, BUT I found a strange and annoying... -
