Hello, i bought a used mb, can post, but blown 2 new Nichicon 1000uf 6.3v when i changed it, then i ask the previous owner, he said the problem is the audio chip, Via VT1708S, i took a look then find out a pin from the chip is broken, the problem is the chip is already damaged phisically, the first big question i am asking is may i desolder completely the audio chip and it wouldnt affect anything but no sound????? 2nd, can someone tell me the cap spec behind the usb and audio I/O? It has a 1000uf 6.3v cap but i want to make sure.

Re: Asrock H55M-LE
Before removing the sound chipset (an Alc 88something which was heavily burnt ), the Intel DG41 couldn't even boot , so guess your problem will the most likely disappear .
In case everything went fine , it's better to disable the integrated Audio chipset in Bios ... good luck .Comment

This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.
There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as... -
Common SPI bios chip programming Questions and Answers

Q: I have a bios request,i can`t post my backup as i can`t read from the chip.
A: If you can`t read from it how do you expect to write to it ?.
Q: Why is my bios chip unreadable ?.
A: The programmer is faulty or has a worn or broken zif socket.
The USB cable is frayed,connector pins worn or some other physical damage.
Not enough amperage or voltage to power the programmer properly.

Long story short:
- dad converted Asus Chromebox CN62 into Windows compatible, with mrchromebox BIOS, years and years ago
- gave the computer to his son a couple years later
- son now decided to revert it to Chrome OS, to sell it as original (re-writing BIOS with the backup one created by his dad)
- too lazy to remove the board from the case, thought a voltage regulator was the BIOS chip (you know... it has 8 legs)
(seems like the story was not that short)
He used alligator clips to read the chip. No luck reading it. Removed chip and placed on a SOC-8... -

Thanks for any help. The board version is DAZAARMB6E0 REV: E. The bios chip is winbond 25Q64JVSIQ1736. W25Q64JV is not available in AsProgrammer -- only BV CV FV or FW_1.8c. The chip won't interface with asProgrammer and a CH341A. When I have this chip on the board, the laptop will not post but when I plug it in to power, the blue LED lights up, also the orange when the battery is connected. When I push the power on button, keyboard backlight turns on and the fan starts briefely then turns off. But I can't do anything to program this bios chip so I bought another one.
