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... -
Is it possible to program npce388na1dx io chip by rt809f programmer ? Is there any way ?08-21-2024, 01:41 AM -
Hi, I'm working on a MSI laptop, Motherboard number MS-16W11, GF-65 Thin 10SDR-459US. Went to another shop because the screen was flickering, but it was working well on an external monitor. The LCD was ordered and the laptop was returned to the customer and it no longer worked. It was then sent to another tech (by the shop who ordered the LCD) and the EC (ENE KB9028Q) was replaced with a donor from another MSI board with different board number and no programming was done. It looks like work was done on PU6 (TPS51225) as well as one of the GPU mosfets was burnt (I removed all three GPU mosfets).... -
I have RT809F but i don't have PEB1 extension. i wanna buy PEB1 but i'm not sure if it supports IT8227vg in Lenovo K14 gen1.
i wanna ty to unlock it using RT809F and PEB1.
maybe someone here tried to do it using RT809F.
any suggestions? -
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...
