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 have a problem with +5V ALW and +3V ALW. These voltages are generated by RT6575 IC.
For correct function RT6575 needs 5V_EN and 3V_EN. These values are provide by KB9022Q chip.
I replaced KB9022Q and flashed, yet not 5V_EN and 3V_EN.
My question:
If there is no 5V_EN and 3V_EN , does it mean that I did not flash correct EC( embedded controller firmware) to that KB9022Q?
Or 5V_EN and 3V_EN does not depend on firmware running in KB9022Q?
Thank you for help... -
Hello. I have an Inspiron 7501 here, it's the same as a Vostro 7500 in some markets (no clue). I was looking to replace the LCD, the panels included with these models are terrible.
I have the schematic and it is a 4 lane eDP port on the board but the pinout seems quite weird, my question is if anyone recognises this weird pinout and knows of any other Dell models that may use it or even any compatible panel models. I have the 40-40pin cable that was used for the models with touch but do not need touch capability, was just looking for a better quality screen and higher refresh to actually...10-02-2024, 04:54 PM -
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.
