The charging indicator light on my ASUS X54H laptop is always on even when the charger is disconnected.
Windows also shows ''Plugged in'' when charger is not connected.
This problem started year ago gradually, when unplugging the charger the charging light took several seconds to disappear, then minutes, and now almost always on even when unplugged for an entire day.
Strangely, before sometimes immediately when plugging in the charger the charging light went away, and later came back with it connected.
If I let battery run out and say it has 3% Windows will... -
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... -
I got a 15-IIL05 that failed to turn on BUT IT DID TRY TO TURN ON and then turned off after 30+- seconds, i disassembled it and found a screw loose inside the case.
With charger it turns on, fan spins but gives no image.
Tested main mosfets no short, tested 3.3v,5v,DRAM, CPU etc and they were present.
Reflashed BIOS, same problem.
Replaced both main mosfets.
Checked main mosfets again and i noticed that they closed once the laptop shut down, so i decided to bypass them and used a bench PSU to check how much power the laptop was drawing while trying to turn on, 20v@3A,... -
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... -
Hi Community,
I've got the above model that activates the relay (clicks) and powers on the LG logo power light on when turned on. It then almost immediately turns off. I not noticed any image on the screen or heard any sound during this brief period.
Checks show:
3.5v on SMPS on (in off state, no other voltages present incl pwr on)
On pressing power button > the 3.5 pwn on voltage, 12v and 24v lines appear on the SMPS connnector between the main the SMPS but then all drop the zero in 1-2 seconds
Disconnecting 24 to TCON connector and powering on shows...
