Dell G3 3579 Bricked BIOS / KB Fix

[mgrharry]

Was trying to fix a Dell G3 3579 that had slow kb and no battery charging issue after BIOS update to v14. Tried loaded v13 BIOS using /forceit command (since battery was under 10%) which resulted in a bricked computer. A dump of the BIOS is attached.

I tried flashing the BIOS posted by SMDFlea in a recent post from someone else with the same model who was also trying to fix kb issue and it does post with that BIOS but fans go full blast and it shuts off after about 5 seconds. Maybe that model had slightly different specs.

Any help much appreciated.

In the interest of clarity, the BIOS dump is from after I tried the /forceit command to downgrade to v13. I didn't have the foresight to dump it before trying that sadly.

This dump doesn't work for me. The problem with the computer the same. After bios update due to bad keyboard. the computer has stopped charging the battery. the power supply does start / stop on / off

In the dell bios update there are 2 EC firmwares,ME Firmware and a 9MB bios update. The 2 EC files are different, 086F is EC 1 ,and 0870 is EC 2 .The 9MB bios update contains EC 1. There`s another thread with a bios that has the 0870 EC 2 FW - https://www.badcaps.net/forum/showth...highlight=3579 See post #1 ,"oryginal no video.rar" is the one.
So does that laptop have a different spec to your model,or is it the motherboard revision number ? ,who knows. Is the bios update flashing the wrong EC ? ,surely dell wouldn`t do such a thing ,but microsoft would.
Try the attached bios, the first has the 1.14 bios update merged and the 0870 EC 2 ,+ clean ME FW but no service tag or win key. The second is just to test, its the same as the first but with the service tag and key.

Re: Dell G3 3579 Bricked BIOS / KB Fix

Ahh brilliant! Post, kb and charging issue are fixed. Went ahead and flashed TEST2 version with ST and key. Secure boot does fail validation however, but if I turn it off I can boot without issues. Any idea what that's about?

Disabled UEFI firmware capsule updates to prevent Windows from "helping out" with a BIOS update in the future.

Which BIOS fixes the no charging issue. I've been using my laptop battery less for close to two years now, bought a battery, worked fine but didnt charge.

No issues at all it just doesnt charge... bought an SPI Programmer, coming in soon, just need to know in which BIOS things went south

If your old battery was working ok and charging theres nothing wrong with the bios. If the battery you bought is genuine and not fake then contact the seller for a replacement. If you bought a "compatible" one,then i`d also ask for a replacemnt or a refund,there`s lots of shitty batteries in the marketplace.The best ones without a doubt are genuine ones.

I'm experiencing similar problem with LA-K033P , device has 3 different models listed in the bios version. 0A23,0A24,0A25. After windows update, keyboard gone crazy. Right side of the KB presses multiple keys while the left side from the middle works fine.
How do i incorporate different EC versions into the original bios i dumped from the mainboard? Can you please share some information ? SMDFlea
