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,... -
I have an RC radio handset(Taranis QX7) which doesn't have internal battery charger which means I had to remove the battery every time I needed to charge it.
So to improve it, I added a 15W USB-C charger board(link) inside and soldered it to the same connector on the PCB where the battery plugs into, great, now I can simply charge it with a USB-C cable.
but the problem I found is that after the radio sat for two weeks without being used the 2S 18650 battery that I'm using was at 4.2V!
So the battery is backfeeding the charger and being drained.
How can I prevent... -
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... -
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...
