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... -
I have two such machines which is having this issue. After shutdown the system starts on its own in a minute. It does not start immediately. It takes around 20-40 seconds before it starts again on its own. This is driving me crazy and not sure where to start ..
Some very important points :
- Laptop does not auto starts after shutdown if adapter is connected.
- It will only auto start after shutdown if the laptop is in BATTERY only mode.
- I have tried replacing batteries with a known
- if I shutdown the laptop with adapter connected and lets say remove the adapter after 5-10

Hi everybody,
I have a Dell Vostro laptop with the VEGAS/TURIS SKL/KBL 15341-1 motherboard. Without notice, the other day the laptop was dead and as soon as I plug the charger in, the LED on the charger itself shuts off, as if detecting a short circuit in the motherboard. Measuring on the board between + and - of the plug shows no evident shorts (readings are in the hundreds of kOhms). If I plug a bigger charger with a higher current limit, it will stay on and some chips get hot. Using a thermal IR camera, a couple of mosfets get hot (but, testing them, they are not shorted, I think they... -
Hello guys,
I've got this motherboard with me that turns on when the charger is connected(without pressing the power button), the fan is fully spinning and it doesn't display anything. there is led flashing 3 amber 5 white. voltage readings are also weird, sorry I couldn't find the schematics for the board.
Voltages are as follows,
@ PL5301: 1.015V
@ PL4401: NO voltage
@ PL4501: 5.100V
@ PL4502: 3.408V
@ PL5101 near RTC: NO voltage
@ PL5001, PL4801 PL4802, PL4701: NO Voltages

Looking forward for your guidance...
