Hello everyone
I have been working on this laptop mentioned in the title, it initially had a blown PQ4410 mosfet. After I replaced it and repaired the damaged PCB the thing started working again, but there is still another problem. The laptop won't recognize genuine battery and charger. I have 3.3v KBC PIN36 PS_ID and this is pretty much where my knowledge ends.
Where should I go next? Replace the KBC or measure something else?... -

Hi, the pc does not recognize my SSD, I was testing Volt and the SMC_OOB1_D2R_L, and gives 0.03v approx, and it should provide 3.3v I think, what can be the problem? maybe is the resistance (R86101) I cant test it with my multimeter too small, but I don't think that would do the V go to 0.3v, and SMC_OOB1_D2R_L has continuity with the test point. I think all other pins are okay.

Hello! : Laptop model: Acer E1-510 Z5WE3. Regardless of the OS (W10/11/8), it doesn't recognize the wifi mouse until several resets. Tried all possible drivers.
I brought new Bios- Z5WE3214W v. 2.14A. In vain! Does anyone have a solution? Thank you!
