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 -
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... -
Hello:
On the above laptop which wasn't charging I found only a tiny drop of water damage exactly on a few components by the BQ25713 Charging chip.. Bizarre how only that one 3mm square for it but it did..
I looked up the BQ25713 datasheet and replaced the 10K pull up resistor on the CHRG_OK line and now it charges!
But on the IADPT line which seams to be a resistor (137K) to tell the chip which Inductor is in use it is corroded also.. (Inductance Detection Through IADPT Pin - from datasheet).
So my question is what are the implications of leaving... -
Hi, exactly on the August 2023 i saw a YT video from "electronic repair school" channel, where it says a technique how to recover dead batteries not charging, probably them has been left uncharged for too long and became "locked" by internal circuitry to avoid wrong chargement by laptop, i'm still wondering why every cellular phone also the oldest and cheaper has a built in slow charge modality to avoid danger on li-ion cells, and on laptop i' ve never heard of that option, only stupid lock modes so those are ready for the trash bin, this maybe due to bigger size / more danger,...
