Re: laptop battery repair
True, but most only repair NiCd and NiMH and will say "no way" to a Li-Ion pack.
The potential for a Li-Ion pack to do "bad things" whether re-built correctly or not, scares the re-builders, as they don't want the liability.
That and some packs have some "smarts" on them, that sometimes prevent rebuilding them.36 Monitors, 3 TVs, 4 Laptops, 1 motherboard, 1 Printer, 1 iMac, 2 hard drive docks and one IP Phone repaired so far....Comment

Hello Everyone!
I have an Acer Aspire A315-42 laptop. I generally leave it on for long time by closing down its lid (so it enters the sleep mode). Recently, it rained quite heavily in out area. And the humidity and moisture seem to be high. So one late evening, after I opened the lid and turned on the laptop, it did power on as the blue light turned on but after it booted to the desktop screen, just 5-10 seconds after both the screen and blue light went out and laptop shut down (the blue power light turned orange). And after 2-4 seconds that orange light went off and the laptop died....06-28-2025, 02:57 PM -
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... -

ISL6257HRZ ISL6257HRZ-T Laptop Battery Charger Datasheet
Highly Integrated Narrow VDC Battery Charger for Notebook Computers
The ISL6257HRZ ISL6257HRZ-T is a highly integrated battery charger controller
for Li-Ion/Li-Ion polymer batteries. ISL6257 is designed for
Narrow VDC applications where the system power source is
either the battery pack or the regulated output of the charger.
This makes the max voltage to the system equal to the max
battery voltage instead of the max adapter voltage. Operating
at lower system voltage can improve...11-05-2024, 04:43 PM -
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
