Re: Dell E5420 dead
Hello, I am trying to clear a bios Admin password. So far none of the programs I have found online have given me a correct master password. I have read some articles saying you can clear the eeprom chip where the password is stored but I have been unable to determine which chip is the correct one. The picture that was uploaded before shows a 16 Mb and a 32 Mb chip but they said the bios was on a 4 Mb chip. The only other memory chip I have found is an 8 Mb chip elsewhere on the mobo but I don't want to proceed until I'm sure I wont brick the laptop. If anyone can help me figure this out i would greatly appreciate it.

Re: Dell E5420 dead
Hello all ,
hoping someone can possibly help out with an ongoing problem I've had and cannot find a fix for. I have a E5420 and have the bios Locked and unfortunately its one with the 1d3b which as far as I can tell there's no tool to generate a code for it actual service tag (CSP5CT1-1D3B). My next move was to find the eeprom and short it during boot as a suggested video spoke of . After a great deal of searching the only chip i was able to find was an 8mbit ATMEL eeprom AT45DB081D-SU954 from what I've read so far I've found no mention of this chip used on this MB and some mention of multiple chips. My line of thinking when trying to find this eeprom was to unsolder use programmer to backup and with a replacement chip as more backup try and program old or new chip with new image . A few issues i've had are first not sure if I've found the actual chip that holds the password data two the only replacement i'm really able to find is actually the same chip but a 16mbit version and therefore not sure if this will work same pinouts just 16 meg instead of 8? hopefully someone has gone down this route and might be able to help.? I can get some pics if need be . Also one last thing this chip was ironically right under the keyboard and has a little cutout in the plastic so there's direct access to it by just removing the keyboard thats why im fairly certain this is the chip in question though it is possible I may have missed another . If anyone has any thing they might be able to add that would help Id be very greatfull.
Thanks in advanceComment

by mikeybassHi, I hope some one has some advice for me. I searched the forums but didn't see anything relevant. I acquired two identical Dell 9010 Mid Tower computers from a business office upgrade (they were going to throw them out). Both of them have the same motherboard (00F82W). One of them works flawlessly. The other one had a corrupted BIOS. I tried flashing numerous main BIOS and EC files from the internet, but none of them worked. I decided to copy the main BIOS and EC from the working 9010 computer and successfully flashed the corrupted BIOS. This got the computer able to boot again and run norm...

by jhanraHi there masters, recently i got a dell 5400 chromebook and wanted to install windows, i searched the internet and i found out other people also wanting a UEFI bios for this model, i searched there is a R/W legacy, but there are bugs like keyboard/trackpad not working, and hard to install.
so i decided to try to port one, this bios is based on dell 5400 windows version, i am testing this bios for a week now an found only a little to no bug at all in windows 10, or only a minor issue
in windows 11 sound driver compatibility, but overall its ok, for me i can deal with it, 😅😅😅...-

by Habble7The Samsung S49CG934SU monitor does not power on - no LED indicator activity and no response to power button. However, when 21V power is connected, it immediately draws 0.8A of current with no display output. The motherboard processor gets warm, and there is continuous reading activity from the W25Q128BV BIOS chip.
Suspected Cause:
I suspect the BIOS may have been corrupted during a power interruption while updating the firmware. The official website provides firmware updates, but they can only be installed via USB flash drive.
