Does any of you know is it posible to turn the NVIDIA GPU off via the bios? Mine doesn't show up in the device manager, and there is no voltage to GPU...Intel works, but it takes 20 seconds to boot up...

Lenovo IdeaPad L340-15IRH FG541 FG741 NM-C362 water damage no GPU power
The board is [B] FG541 FG741 NM-C362, and the laptop was water damaged,but not too much.
I cleaned the board and laptop was blinking white light , 3.3V and 5V were present, CPU had no power, i analyzed the startup sequence and found that there is no VCCSA on the CPU, i traced it to the PU2901 and found the Vin pin 47 had no input, resistor 2Mohm was burned OL, replaced that and now the CPU is getting hot and i get the keyboard backlight now and fans spin, but still blinking white light and no image on the screen, but now the GPU is cold, and i remember when i first took the board...

Strange problem charging battery Toshiba Z50-E
First of all i haven't found the board number other then FLESSY2 G4227A A4227A etched under the DC in connector...
The problem is laptop does not charge the battery...Laptop works on battery and work on charger, but doesn't charge the battery... when off, it pulls 0.13A ,when turned on it pulls around 0.500A and has spikes 0.6-0.8 A when booting, i found that ISL9238H is the charging regulator and i replaced it with ISL 9538H and it's all the same...i checked all the passive components and all seem to be ok...
Anyone have an idea what to look for next? The battery...

CLEVO N970TF turns fans to the full and goes of
The laptop is CLEVO N970TF with i5-9400, RTX2070, i haven't disassembled it yet to know what is the board number, i will update that later, but the issue is laptop turns on normally and works for about 2 minutes,then both fans turn on to the max and in 30 seconds laptop shuts down! Nothing is warm or even close to overheating...
i manage to get linux up and running and monitor the temperatures from all sensors, and the peak one is 51 celsius from a cpu cores...
So something is acting up and thinks the laptop is overheating? How to foul the board into thinking everything...

Win 11 doesn't work, i had to use a win10 laptop to extract it...
And i solved the issue, the issue was a bad chip...i salvaged a different one ,flashed it and all was good...i got the manufacturer mode active, turned that off, inputed the information and all is good...interesting , the old chip flashed succesfully but the bios was in recovery mode and tried searching for USB with bios update every time i powered the laptop, and flashed the bios again and again in loop,that's when i figured the chip was bad...

I also got this laptop and after the firmware update from windows board gives 5 long and 3 short blinks...I tried a flash from this site and it works, but it needs 30 seconds to boot and it asks for a bios recovery ,and when i do the recovery from USB it goes to black screen again, but this time no blink codes...
i have the original dump from the chip, can anyone fix it?...
