Thanks for your help mate.
I replaced both MOSFETs with components from my donor boards. The laptop is running again now.
Many thanks for your help.

Hey mate,
Thanks for your help. PQ205 and PQ5400 are faulty.
PQ205 = AONR21357_DFN8
PQ5400 = AONS32314_DFN8-5
Can they be replaced with similar ones?...Leave a comment:

Lenovo IdeaPad 3 17IAU7
Model PF9XB4615434
Mainboard NM-E341
Hey Mates,
I need a bit of advice. The laptop works when I connect the AC or USB charging cable but leave the battery out. If the AC or USB cable is connected and I connect the battery, the charging LED lights up, but it doesn't charge. If I connect the battery and then plug in the AC or USB charging cable, a short circuit occurs and the input MOSFETs get hot. Can anyone help me find the fault?... -
Sry for late response. Could not test it because not connection to the MEC1723 even over jtag with svod4Leave a comment:

LENOVO IDEAPAD SLIM 3 I4IAH8 bios
LENOVO IDEAPAD SLIM 3 I4IAH8
SN: PF4J8CRZ
Hey mates,
I have a problem with my IdeaPad 3 Slim.
When I turn it on, the ESC key, Caps Lock, power button, and power control lights stay lit, and the screen remains black.
I can't press the Caps Lock key. The correct current is being applied to all coils.
I tested the BIOS files from post #23, but without success.
I'm attaching both original BIOS files. Could someone check if there's an error?
By the way, the 1.8 V coil is receiving the full 1.8 V as soon as the power adapter is plugged... -

So far I've been a silent reader, but now I need your help
I bought a laptop. The seller said the bios was locked. I was looking for a way to remove this ban.
I then got the CH341A and pulled the corresponding files from here https://www.badcaps.net/forum/troubl...evices-and-ele... -
hi Mate, I have the same problem with the same laptop. First of all, thanks for the bios files. One question, I use the CH341A tool to flash the BIOS. The main BIOS has the chip MX77L25650FMI42A. Unfortunately, the programs for the CH351A tool do not have this chip in the data. did you flash the chips too? If so, how did you solve the whole thing? For completeness, the backup chip MX25L25673G is available from Neoprogrammer. best regards and thank you very much!Leave a comment:
