BIOS request for the above model, please.

If someone could explain what tools are needed to convert the .exe BIOS from the manufacture websites to .bin I would really appreciate it.
Thanks...

Still the same... fan spinning, keyboard and power lights working but nothing on int or ext display. I'm thinking it could be something else and not the bios
The only other thing i have noticed is that on the bios copy you repaired it's only working from the battery and 0a showing on bench supply. The other versions on bios all showed 1-2A.

Sorry, my bad. I already injected 0.8V/4A into the shorted side and the thermal camera confirmed that the PCH was at fault.
I've returned it back to the customer as unrepairable.
Just a quick question as i mainly repair Apple products, what does ALW mean? is it a always on power rails?
Thanks for your help.

Readings below are in diode mode format, Sorry only just read back your post. If you need resistance to GND, let me know.
U8
1-2 = 0.02 --> 3.3v
6-7 = 0.38 --> 5.12v (without button pressed)
8-9 = 0.45 --> 0.00v
13-14 = 0.27 --> 0.00v
5 --> 0.00v
U7
6-7 = 0.00 --> 0.00v
7-8 = 0.38 --> 0.00v
From the above reading, I removed the jump at PJ1801 and the short is coming from +1.8VALW_PRIM....

Acer Nitro 5 AN515-56 GH52T LA-L051P Charges ok but not switching on.
Hello all
I need some help with this laptop please.
It came in, not turning on fully. When i press the power button, i get a blue power light briefly (19v 50mA shown on my power supply) and then it turn's off. With the battery connected it charges it fine (19v 1.6A).
Still shows the same symptoms with just the motherboard so i know it's a problem on the board. When first connecting the power without the battery connected i get 10ma briefly before going to 0ma so i believe the EC chip is fine (I could be wrong).
I've checked around the board for...

ASUS ROG ZEPHYRUS G14 GA401II BIOS
Hi all
I'm hoping someone can help me.
I have here a GA401II ROG where the customer decided to turn off the laptop whilst it was doing a bios update. At present it's charging and pressing the power button i get the fan spinning and lighting up but nothing on the screen.
I tried following the instructions on the ASUS website but that's as much use as me building a cabinet from IKEA
I was wondering if anyone could reprogram the original or supply one that works. I included the original along with images of the case bottom and the motherboard....2 Photos

Re: Help understanding USB-C controllers
OK so i switched the PD controller back and after searching i found a short on a coil/MOSFET. After applying a very small voltage the CPU is the culprit.
Dead board. Thank you for your help

Re: Help understanding USB-C controllers
Thanks Mon for your reply.
Yes it is bidirectional and i will post a pic tomorrow.
I don't think there's much hope for this laptop as it's a BGA chip and i don't have a CY8CKIT-005 programmer.
