Re: dell e6440 no battery detected
Battery not detected will be:
1) connector fault
2) connector contacts not soldered
3) ESD diodes clamping the SMBUS circuits - remove PD2 & PD4 and test again. My bet (of a fresh box of Haldiram's motichoor ladoos) are on this fault. Killed 3 days on a macbook (other shops gave up on it) and it was down a tiny tiny SMD ESD dual didoe - needed tweezers to solder it.
See attached. Post your updates.Attached Files -

DIODE. LOL, salivating while typing ☺️SMD ESD dual didoe
Good job. The ESD diode did it's job to suppress a transient event at the battery connector. Do replace it if available.Comment

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... -
Hello,
YouTube video of the problem encountered: https://youtube.com/shorts/q7TLNv36LUo
I am a pro and I have a problem that I have never seen despite my 7.5 years of experience on my own and my thousands of repairs, on a customer's Dell G3 15 3500.
On this PC I have already changed the complete palmrest because the keyboard was no longer working properly.
I also changed the screen because the PC fell and the screen was broken.
I changed the battery with a new and original battery.
I also had corrosion/oxidation on the... -
recently i was gifted a dell inspiron 5567 for wiping the data on the hard drive. (yay me). however i already have a computer that i use, so i have no need for this computer. this computer wasn't without its problems though.
1. i had to purchase an adapter to retrofit my older style dell laptop battery cable. (not too expensive) ~= 10 bucks for a 2 pack via amz.
2. after that i had to find a spare cr2032 (easily found in my parts bin) and assemble a makeshift cmos battery thanks to some copper foil tape and some heat shrink tubing.

Hi
Dell Precision 5510
Mobo code : LA-C361P
This one came in for battery replacement but without original battery, so original battery and charging history is unknown.
The customer said he bought the computer several years ago second-hand and was told that there was no battery inside but that he could purchase one if he wanted.
So we ordered a geniune battery for customer, plugged it in
RTC battery was also dead and it was also replaced. First boot up brought up warning message;
Funny thing is Service Tag is already set.

Hi great minds. I have this Dell XPS 13 9365 with service tag FK960x2 showing No battery detected and blinking white light continuously, meanwhile there is a working battery in it that is still backing up fine. Please can anyone help with the solution?
