Hey.
I have a similar problem as most other users in this thread where the laptop takes a few seconds before the dell logo appears while booting. Additionally, when I power on the laptop, sometimes it basically does not turn on with the storage light blinking. I have to remove the battery and the CMOS battery to reset the bios, that helps it to boot again. Thought a bios update would fix these issues, but guess what, I can't do that either. the laptop fails to install the update and reboots back into windows rather than the update screen when installing the bios exe file from dell website.
these problems have been plaguing my laptop ever since i gave my laptop to a repair center to reflash the bios because the laptop failed to turn on before that. the reflash however fixed the Wi-Fi problem i had before the reflash as mentioned by numerous people in the thread. Do note I bought this laptop used and have no idea if the previous owner has had it reprogrammed before or not.
I'm planning on flashing the bios again but I'm pretty new to doing it myself, with this one being my first so I have a couple of questions.
1. Can i simply flash any of the previously posted bios files in this thread?
2. I'm planning on purchasing a CH341a programmer for this job. Will that work with this laptop?
do note I'm still researching on this so any input will be helpful!!
Best.

Had the exact problem when I flashed bios on mine but switching ram sticks/slots got it up and running again without any problem.
Do note I have two different speed ram sticks on my laptop, 1333mhz and 1600mhz. With just the 1600mhz ram stick installed, it had the same problem as you described. But installing just the 1333mhz stick got it running. Didn't investigate any further, hence don't really know if that had something to do with it or not

So, i kinda spend significant ammount of the last couple of days trying to flash a new bios, and or unlocking the current bios password with little to no results.
The whole thing started with it being the 8fc8 bios, i found the tools to unlock that but i needed a bios dump. So i pursued that, im at a point where i dessoudered the chip, and succesfully soudered it to the ch341, dumped whatever was on it.
However, the tools supposed to unlock the 8fc8 say that there is no 8fc8 hex inside. And when i followed diffrent tutorials to just flash a new bios onto the chip i got stuck on the... -
Hi 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, 😅😅😅... -
Hello everyone,
I'm working on a Dell Latitude 5490 with a LA-F401P motherboard that has a very peculiar issue, and I would appreciate your insights.
Initial Problem:
The laptop was completely dead, no signs of life, no power LED.
Action Taken:
I flashed the main BIOS chip with a clean dump. This brought the machine back to life, but with a strange limitation.
Current Situation & The Main Issue:
The laptop now works perfectly when powered through the USB-C port. It charges the battery, powers on, boots into the OS, and functions 100% correctly.... -
Hi
i have dell latitude E7270 with following symptoms:
- takes long time to restart.
- sometimes powers on and then off
- sometimes while working it just dies,
From googling online bios clean could possible resolve this?
i was able to save bios and was going to try bios clean myself but get an below error when i drop it in ME analyzer.(unsure whether this sometimes occurs or could be due to bad/corrupt bios)
As ME analyzer gave me an error i just decided to write bios with a cleaned bios from E7270 bios post.
I reinstall...
