I think it should. Confirm the voltage to ground on each pin of the power adapter connector. Be sure the power adapter is the original. How far on the board does the power adapter voltage travel? Does it reach the charger IC? Most likely will be the BQ charger IC so check the ACN / ACP pin and confirm if the 19v reaches this point. This region is after the usual DCin mosfets.

Hello,
Dell Latitude 5420 P137G
Board: LA-K491P REV A01
I have received this laptop which was described as "does not power on or accept charge." Battery shows no sign of charging when charger is plugged in, nor does the board show any signs of life when battery is unplugged and charger is plugged in. No light from the LED at all or any other indications of activity.
Board seems to have no shorts, all power rails are fine and show high resistance.
When charger is plugged in, voltage is present in 3.3V rail but absent in others.... -
Hi, I have a Dell Inspiron 7567 LA-D993P that I've just got running.
There was corrosion around PU1503 which shorted PC1518 & blew PL1504. (Reference pictures attached)
I've replaced PC1518 & PL1504 & the laptop is now running however I now have another issue.
Here are the tested scenarios:
1. With the laptop running on battery, I plug in the 150W charger & the charger shuts off (no LED, protection mode) but the laptop remains running on battery.
2. With the laptop off, plug in charger (LED says on) & the front charging... -
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 a Dell Latitude 7280 which complains during boot-up that the charger wattage cannot be determined. Tested with two different chargers.
Any common faults that could be fixed?
I replaced the DC jack, the original DELL LATITUDE 7280 DC30100Z300 0DP4VC.
How does the communication between the charger and the PC work?... -
Hello, I received this laptop with the following condition: When I turn it on, it shows the ALIENWARE light and the Alien button lights up, then it does not show an image and it restarts constantly, as the customer had already informed me that the battery was dead, I connected an original charger that I had it for testing, the machine turned on normally and I was able to enter Windows without problems, after a while of testing I noticed that it is very slow (like a Cyrix 425...), and after performing a CPU test the frequency is
below normal, as if it were operating in an extreme energy...
