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. But i just cant do it with XMC chips, is there some specific program that i must use? (i am using NeoProgrammer)

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... -
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... -
The mb under repair is FAROE_Dis_X32_MB-MV 18742-1(HP). It came completely dead. Found 19V is not passing thru 1st dc-in mosfet. After diagnosis, replaced BQ24781 with BQ24780S and it solved that part of the problem. Next found +3V LDO is shorted, so removed the +3V PWM but still shorted. Removed KBC9028Q-c and short is gone. I've soldered new SY8286BRAC and KB9028Q-C(both new). DC jack is glowing now but mb doesnt turns on as kbc needs programming.
I've SVOD1 which doesnt list kb9028 as an option. Still tried selecting kb9022 but doesnt work. The support has ended from SVOD-so...
