Strange! Acer laptop not powering on but charging the battery (orange light on when charger and battery plugged in).
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. It doesn’t turns on after pressing the power button.
I opened up the laptop to inspect the motherboard and couldn’t notice anything unusual. However I noticed that when both the a/c adaptor and the battery are plugged in, then there is a blinking orange light that becomes stable after some time which indicates that the battery is charging successfully.
So it seems to be a clear case of the laptop not powering on (dead laptop) but able to charge the battery.
I am newbie in electronics but do have a very very basic understanding on power rails and some motherboard components. Currently I don’t have access to multimeter, but I can get one sourced in coming weeks.
I also did manage to get the schematic and board view of the laptop. The motherboard model for this laptop is EH5LP LA-H801P.
It would be really helpful if anyone can guide step by step as to where and what to look for (example tracking voltages, identifying shorts etc). It would also be a great learning experience for me.
Look forward to hearing from you.
Thanks.
