Hello Guys,
I received Toshiba Qosmio X755 that has a charging problem and I'm stuck trying to figure out the problem.
- When battery is unplugged i works without any problem.
- When I plug in the battery after plugging in the charger, it works correctly and the battery is charging.
- When I plug in the charger after inserting the battery, it stops working. ( voltage dropped and consumed 8A, reaching the maximum capacity of my bench power supply for 5 seconds, and stop working after )
Can you help me diagnose the problem? I have attached... -

The problem is laptop does not charge the battery...Laptop works on battery and work on charger, but doesn't charge the battery... when off, it pulls 0.13A ,when turned on it pulls around 0.500A and has spikes 0.6-0.8 A when booting, i found that ISL9238H is the charging regulator and i replaced it with ISL 9538H and it's all the same...i checked all the passive components and all seem to be ok...

Hello guys,
I have a problem with charging circuit in this laptop. Unit came with no power at all (USB-C meter was cycling turning off and on). I discovered that when I unplug battery laptop works on charger only. So after few measurements I found shorted 1st dual mosfet AONY36324. Unfortunately i was not able to order exact this one, so i ordered AONY36352 which i believe is the similar one. Now the problem is, when i connect battery and charger USB-C meter is not cycling anymore, it starts charging (reading 20V@2,7A) but after few seconds it is going down to 20V@0,20A and laptop... -
Hello Everyone!
I have an Acer Aspire A315-42 laptop. I generally leave it on for long time by closing down its lid (so it enters the sleep mode). Recently, it rained quite heavily in out area. And the humidity and moisture seem to be high. So one late evening, after I opened the lid and turned on the laptop, it did power on as the blue light turned on but after it booted to the desktop screen, just 5-10 seconds after both the screen and blue light went out and laptop shut down (the blue power light turned orange). And after 2-4 seconds that orange light went off and the laptop died....06-28-2025, 02:57 PM
