My GX280 has the usual problem and before changing out caps, I would like to be sure its not the ps. The 12v. leads all measure 11.8v. I know that is within tolerance, but is it possible that these Dells are really finicky about voltage?

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 there,
I got 2 Dell laptops with a locked bios (dell management protection).
When I sent the dumps to this forum I got unlocked .bin files.
The issue I am getting the voltage on the bios chip pins has changed once I soldered the chip back (with the unlocked even original bios file) and doesn't turn on anymore.
Before I started to re-program the chip the voltage on the pins were 3.3V almost on each pin. Once I soldered the chip, voltage changed to 1.9V or 1.3V on few pins. No 3.3V anymore.
I appreciate any help to get me this... -
Hi,
Could someone help trying to unlock this BIOS, seems that Dell have changed the layout of new Dell Pro 8FC8 bioses from checking HXD - 4000 bits do not need changing, only 2000. However after FF the section starting from '01000' upto 2000 bits and then soldering the chip back it seems that the microchip on the motherboard is recovering the bios back to original settings after first boot. Has anyone found a way to crack this extra layer of security Dell have implemented? Seems both HP and Dell have upped bios security to match Lenovo by implementing extra measures on a separate... -
I would like to share my experience about charging issues with Dell power supplies with the tech community. I am working on a Dell Inspiron 5590, Mainboard 18778-1 with charging problems. The device can be switched on and works so far, only the message appears at startup:
Alert! The AC power adapter wattage and Type cannot be determined. The battery may not change. The System will adjust the performace to match the power available.
The power supply unit is not recognized in the Bios and the charging process is set to "idle". I use original Dell battery, type... -
Here's my device:
LAPTOP: Dell Inspiron 5100 (2003) 2.4Ghz p4, dual-boot: Windows XP pro, sp1 + LinuxMint ( LM 17.1 MATE ), with 128GB ssd, 512mb ddr sodimm.
The 5100 runs fine, even after 19 years of daily, gentle use, "always on", and on adapter power only.
HOWEVER, over the past 5-6 years there has been a restart-up issue (after power down or power loss --- I leave all my PCs/laps in daily use in ALWAYS-ON condition, even going months w/o re-boots, but the inevitable always happens) .
Seconds to few mins after pressing the power button to restart...
