Laptop Question
Hello,
I'm working on a Lenovo T460 that has been having trouble charging as of late. Its worked well since I've owned it for a few years. When I went to use it the other day it was dead and wouldn't turn on (was sitting on an Anker 65W GaN charger). After some fiddling with the charger I got it to turn on and start charging, but seemed like the charger was not working as it should (took a few plug and unplug cycles to get it to start charging).
A day later it was dead again and wouldn't boot/charge no matter what I did. No lights or anything when... -
Hi, I have a Dell Inspiron 7567 LA-D993P that I've just got running.

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

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...
