Re: Dell Laptop asking for 1F5A password

Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.
Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,... -
Dear all,
Bought this used Dell laptop PP24L(studio 1435) in Jan 2022. It was running smooth on 64 bit Windows 7 pro from processor Intel core Duo T6400@2Ghz with 2GB RAM. The laptop battery was charging and working fine until few months back the opening screen will display something like "replacing the battery warning", press F1 to continue. Normally i press F1, the laptop will proceed to Windows and i can use as normal.
But last week, after i pressed F1, the laptop just shut down. I suspected the laptop battery is dead. So i pulled out the battery and... -
Hi, I'm unable to find the motherboard number (PPID number) or the board view for this old laptop. My laptop won't start, and when I enter the serial number on the Dell website, it says the number is invalid. The sticker on the bottom is unreadable because it has faded over time. Unfortunately, I'm unable to start the laptop to use the power cell or explore other options.I needed the CMOS Cell & it also seems the Laptop will not start now because of the power switch issue, which is yet to be detected.07-19-2025, 01:56 AM -
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... -
Hi,
I have this laptop for a long time, still it does it's job, like browsing, word , excel. Two years back laptop Hinge base broken but now it's damaging other parts of laptop so I tried to totally remove the embedded display cable from laptop and tried to boot only with external display monitor, but it doesn't boot and gives single beeps. BIOS checking the embedded display to be connected.
So checked the schematics to bypass this issue.
Found something but I don't know how to read this schematics.
Dell 3537 mobo 9982p rev 3
Schematics attached,...
