Re: faulty IO Chip
the problem can be from every pin
lets say one EX:
i had a dell i5 e series no backlight.
i try to force it ; ehh did not went well, did a reflow and after i found out it was not turning on the BL from KBC. change it and everything was fine.
many problems can be seen it that SIO chip but the difference is distinguish the input output and feedback pin.
input - supply
output- for other device or switches
feedback - NB, SB, SUSON all power OK, s0, s5, s3,
i will take a holiday and give money to someone in UK to teach me those pins because i learn to slow.
i think the SIO its the god of problems. if you know the SIO you know how to solve everything.Last edited by dj_ricoh; 03-15-2015, 05:36 AM.Just cook it! It's already broken.Comment

Re: faulty IO Chip
Basic knowledge of electronics and little more about discrete systems is a good starting point.
Ramee - sorry this guy does not give any knowledge which will help you in the future, there are multiple parts of this video where he gives wrong information.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... -
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... -
Hello, anyone here have updated ezp2023+ chip database in .dat file format.

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.
The BIOS... -
Hello, first of all, excuse me, I am using the translator, English is not my native language.
I have a Lenovo ideapad 330S - 14IKB laptop.
The tablet did not recognize me when I connected it, so I checked the device manager and I realized that there were many with the exclamation mark, so one by one I began to update their drivers until the sign disappeared of admiration, I even updated the BIOS, and the laptop rebooted normally and worked, so far so good, but the tablet still did not recognize me, I read on the internet that it could be due to a...
