if yes then how can i do it

Dear friends, I want to share my experience repairing an ASUS TUF FX506L gaming laptop motherboard: DABKXDMB8E0_F_BKXD. Boardview and schematic are available, as well as the BIOS and ITE ROM.
When the customer brought in this laptop, it was initially dead; it showed no signs of booting for any reason. After hours of measurements, checking each stage, MOSFET, and seeing if there was a short circuit in any capacitor, I discovered a strange 0.7V leakage voltage on the 3V_S5 rail, particularly on the PL9 coil, with the board not powered on. There were 3V_LDO and 5V_LDO voltages, which... -
Hi everyone,
I have a board with a dead pwm on mp2886a. I order the chip without thinking about programming, and now I just realize my mistake.
Someone know if it's 100% needed to program the chip ? And if so, how to program it ? I see some dedicated board and software but, software is a bit tricky to me, the bad part of the job...
p.s : with the dead pwm chip, the GPU work fine when I disconnect the shorted pwm (6), with the new chip Pgood is 0 and the gpu doesn't start, so I guess it need to be programmed, or it's fake chip..
p.s 2 : Sorry for my... -
Sup guys i've been having a trouble with XMCQH128A chips, this is the only model that always fails to programming. All the others models and brands like Winbond, cFeon, etc. All works fine.

I am working on a Dell precision 3560 with a locked BIOS. I used AsProgrammer software with the CH341A v1.7 set at 3.3V. AsProgrammer is the only software that works with the CH341A that lists the W25R256JV. Reading the 25R256JV with this setup returned garbage results. I switched to my T48 programmer and it identified the chip as a 25Q256JV and appeared to read the chip perfectly.
I need to reprogram the chip but I am not sure if the programming the 25R256JV with the 25Q256JV setting will work. I don't want to risk bricking the computer.
Anybody have any experience or...
