Re: da0z8cmb8d0 rev d need boardview
We love boards that do not charge
This forum should be renamed to badchargers.net.
Do you have the schematic already ? Consider to post your same details in the laptop forum for feedback from techs.
Is the battery a known good battery ? Try another battery if possible.
Is the battery detected by the Windows operating system?
Start with a voltage measurement of each pin on the charger IC @ PU9 (BQ24737RGRR).
Also post each voltage on the battery connector so we can confirm if the SMBUS / I2C interface is working. -

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 badcaps community, Im very begginer guy which transitioning from IT into Tech industry due to finding it more logical in long-term.
Recently had my laptop broken.
Left 220v cord disconnected from power supply for 1hour and cameback - laptop was gone.
Drained bios, laptop started and then shutdown instantly. (battery showed 0%)
It did not turned on again. Checked one last time with unscrewed battery (wanted initially just replace the battery as it had only 50% capacity left.
That was my quick "diagnosing". And it slipped from my hands while... -
I bought a Vostro 3400 motherboard (LA-K033P) to upgrade over my damaged Inspiron 5593 (LA-J091P) board. Everything else is ok except for the battery. This battery I am using now is already a replacement one since I disposed of the bloated original one. Back in the Inspiron 5593 motherboard, the battery charges fine and is identified just fine. However, with the upgraded motherboard, suddenly the replacement battery is labeled as "Not a dell battery". When I borrow a similar battery from my colleague (which did not have replacements yet), it is identified and charges just fine.

Hello guys, i need help with this problem, I have a NM-D041 mobo, it came with low impedance in 3v linear regulator rail, the cause was a damaged EC controller ITE8227e-192. I ordered a new one and replaced it. This laptop have a different chip for keyboard management and it8227e pins for programming ITE chips are not accesible through keyboard interface, I flashed it using i2c interface pins with vertyanov programmer because laptop was dead and SPI flash didn't have power (only 3v EC) so it couldn't access firmware stored in SPI memory. I read SPI and extracted it8227 firmware from original BIOS... -
The ISL88739 & ISL88739AHRZ are a highly versatile combo battery charger
configurable for operating as either a Hybrid Power Boost (HPB)
charger or a Narrow VDC (NVDC) charger, supporting 2-, 3-, or
4-cell batteries. Both configurations allow the battery to work with
the adapter together to supply the system load when it exceeds
the adapter capability, referred to as system Turbo mode. HPB
charger configuration reverse-boosts battery energy to the system
bus to help the adapter provide the system power in Turbo mode.
NVDC charger configuration...11-05-2024, 03:28 PM
