EXO UX133 the KBC has pin shorted to ground

03-05-2025, 10:46 AM

Hi, on the UX133U motherboard (little info) the KBC (IT8987) has pin 59 shorted to ground, so there is a key always pressed.
Does anyone know if it can be cancelled by modifying the bios bin or reprogramming the KBC?
Thanks.

I replaced the KBC with one from a different motherboard and it worked fine.
For anyone who might be interested, you obviously don't need to program it, just extract the firmware from the BIOS.

Acer Alienware Nitro 5 (GH51G LA-L181P Rev: 1C) & Dell Alienware M15 (GDP50 LA-k452P Rev:1) - Both Shorted PCH (SRKMA)!

by reessi

Hello:

I have both these laptops that appeared to have the same fault so I thought I would have a go at replacing the PCH as something to learn, they both are using the same PCH.

I started on the ACER:

Up on connecting power no signs of life but current is consumed from the bench power supply and the PCH is hot.
All the caps on the top of the PCH are showing 0 ohms and the 3.3v rail is shorted.

I followed the videos from Sorin, Electronics Repair School on Youtube heating from the bottom to install. I practised on around 10 scrap...

[B]Lenovo Ideapad 100S-14IBR EEPROM VCC shorted to ground[/B]

by Duranitron

Lenovo Ideapad 100S-14IBR

need help guys.. Bios ic UX3 - 25Q64FWSIG no 1.8 volts

shorted 1.8ALW volts to ground. eeprom is ok

Findings : i disconnect the vcc from the circuit using jumper 1505 and test the output of the 2Z-3F F0V ic it produces 1.8v so i injected a 1.8v in the vcc of the eeprom and somehow the processor is heating up and it draws 2.090 amps .

my question is how much current does this ic can produce at normal level. does the 1.8vALW powered the processor.

am i dealing with a shorted processor?...

Panasonic TC-P50S1 shorted TXNSC1EDUU (TNPA4782AB) SC Board

by Yanleb

Hi every one. I just want to share the successful repair of my shorted Panasonic TNPA4782AB SC board.

I don't usually do it but so many parts were shorted that I decided to buy the ShopJimmy repair kit instead of sourcing each components individually. Here is the list of components the kit contained, with a remark indicating if I needed that part or not :

D608, good
D618 RF101L4S, good (See warning 1 below)
D619 RF101L4S, good (See warning 1 below)
D865 RF101L4S, shorted (See warning 1 below)
