Re: DAG31AMB6D0 rev D EC rom request
thank you Sir working perfectly, can you tell me how you extracted EC bios from Bios update, what i know is that HP bios update have the Copy option but it will just extract Bios Files without ECComment

Re: DAG31AMB6D0 rev D EC rom request
you said in post # 8 that it works with version 08209, the bios posted in post # 10 has version 08213 and corresponds to another motherboard model, so it can't work..you probably have another problem on the board ... change the bios chip for starters and rewriteDue to a lack of donations, server free space at a critical level, and possible closure of Bios Requests all donations are welcome, click:

Hi, Would appreciate some help.
I have an Apple Late 2013 15" A1398 MacBook Pro with Logic Board 820-3662.
Get charger light but no fan spin or chime. No liquid damage.
Found PPBUS and VCORE both shorted to ground. Other rails were ok.
Removed VCORE MOSFETS U7310, U7320 and U7330. Found U7330 was in fact shorted.
With the 3 MOSFETS removed, get PPBUS and fan spin. VCORE is still hard shorted to ground (0 ohms).
Attempted voltage insertion on VCORE to locate short using bench supply set at 1.0 VDC and 4.95 Amps (max current for my... -
Dear all,
Laptop is Lenovo Thinkpad L480 (boardview can be found in this badcaps topic). When pressing the power button the LED power light turns on, but nothing else happens.
I removed the motherboard, checked for shorts on the main inductors. I found that there is a short to ground on the +3VALW_P rail (@PL201). I soldered a wire on the PL201 inductor, and I injected up to 1.3V with my power supply. Current drawn is approximately 3.2A.
I used a small thermal camera to locate the shorted component. But nothing on the board heats significantly, except the... -
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. -
Hey guys,
i've got this laptop from a friend who gave it to me in a dead state.
The laptop wasn't working at all so i've began my search on the 19V power rail.
It was shorted to ground so i injected voltage and the only thing getting hot was my ground clip from my power supply.
I found that the +1.05V Rail for the Chipset was shorted. i removed the coil and it was shorted on the power delivery side.
The pch seems fine bc the rail has over 50 ohms after i removed the coil.
Still nothing was getting hot so i suggested the chip must... -
Laptop does not power on but has a fix white light on power button, when connected to power.
I found, while trying to diagnose, a hot spot in the motherboard and found it to be a shorted capacitor (see photo below) on the 2.5v (2D5V_S3 on schematics). After replacing it with one from a donor board, still, the board does not turn on...
The usb-c meter reads upon connection 20.1v and 0.00a, with some occasional flashes to 0.03amps. After 10/15 seconds circa, it goes to 5.2v and draws an almost constant 0.07amps. (same behaviour as before)
To my fingers, nothing seems...
