Re: Asus Eee Slate B121
How old is the battery? # of charge cycles?
Does the battery charge with the adapter?
If in doubt, test with a known good battery. -

Hello everyone,
Mark and model: ASUS X571
Symptoms: not turning on. There is only the LED battery indicator working. The owner of the laptop told me this problem arrived one week after having changed the battery. He then managed to power on the laptop only once, and then it never powered on again.
Tests already made:
- Battery is charging when laptop is plugged in. The LED battery indicator turns white after a couple of hours of charge, indicating that battery is fully charged. However, laptop won't turn on anyway, with or without AC plug.
- I have removed... -
My question pertains to understanding the control circuity inside a Dell PT434 type battery used in Dell E6400, E6410 and other Dell notebooks?
Does anyone have a circuit diagram for the inside of a Dell PT434 battery and/or a description of how the control lines work to control this battery?
My reason for asking is I have a battery which I cannot get to charge beyond 1% in a Dell E6410 or E6400.
The LED bar graph charge indicator on the battery shows one LED lighted when the info button is pressed.
I have tried multiple different Dell power adapters. My Dell... -
I'm working on my sister's laptop: Asus VivoBook F510UA-AH51 - The motherboard died so I replaced it.
The original board was:
ASUS X510UNR REV 3.0 A
The replacement board is:
ASUS X510UNR REV 3.0 B (identical except B vs A - I couldn't find an A board anywhere. Visually they are identical.)
It boots right up on the replaced motherboard and everything works fine on the new motherboard - but it won't run off battery. When I disconnect the charger it immediately dies. When I plug it back in and reboot the system - it still shows the battery at... -
I have an Asus TUF machine that doesn't run off battery. Runs off charger ok, shows orange battery charging light and shows battery is at 96%. Battery voltage is less than 0.5v though. It had a short on the 20v rail from a dead cap. Pic attached. Removed cap and replaced a dc in mosfet. Machine now powers and runs fine.
I have also replaced all 3 battery mosfets with no change. The 1st battery mosfet has 20v going in. Pic attached.
Does it sound like a battery ic problem, it has bq2470. Not sure if I should replace that as well at this stage as I'd need to order one.
Thanks.... -
Hello everyone
I have been working on this laptop mentioned in the title, it initially had a shorted capacitor. After I replaced it, the thing started working again, but there is still another problem. The laptop was running off a charger, the battery was reporting 96% charge... but when I unplugged the charger, the laptop died. I've measured the battery voltage - 0V. I think it is locked. (Screenshot from batterymon, below).
I've ordered a new 3rd-party battery, but I think there's something wrong with it too - the laptop boots, but the battery isn't charging. Also,...
