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... -
Hello, I'm looking for bios chip on the motherboard on Dell Inspiron 7610. Server tag: CS4MDL3. I found on the back on the motherboard chip named: Winbond 25Q256JVEQ.

Is it possible this chip to be read AsProgrammer 25Q256JV option and ch341a programmer?... -
Hello,
I bought a Dell G3 3579 eBay. The fault was not mentioned and it did not come with charger. Before trying to power off battery, I did some basic checks on the coils (in resistance mode) to see if there was any short. None were reading short. Decided to power the board to see if anything happened. The keyboard backlight came on. About 5 seconds later, the fans begin spinning at max speed. The white LED comes on at this time, stays solid for a bit and goes off. Fans continue to spin at max. Display is black (no backlight). If I hold down power button, board goes off. I did give... -
My question pertains to understanding the control circuity inside a Dell PT434 type battery used in Dell E6400, E6410 and other Dell notebooks?
Does anyone have a circuit diagram for the inside of a Dell PT434 battery and/or a description of how the control lines work to control this battery?
My reason for asking is I have a battery which I cannot get to charge beyond 1% in a Dell E6410 or E6400.
The LED bar graph charge indicator on the battery shows one LED lighted when the info button is pressed.
I have tried multiple different Dell power adapters. My Dell... -
Hey, i bought a Dell Optiplex 5000 8fc8 with chip W25Q128JVSN.
I also used the CH341A programmer but my usb cable (i didnt attach it directly into the pc, i used a cable between) was corrupted. So i made a dump. Then i removed the password but unfortunately the dump had a loose contact so it was corrupted. And i've also overwrited the chip and now i dont have any dump anymore.
Can someone help me? I am stuck since hours and i cannot find any bin file anywhere.
I tried to extract the EXE for BIOS installation from dell and also the rcv file but i didn't manage to do that....
