Aspire V5-431 drains the battery when powered off

I've owned this laptop for several years. A bit under-powered, it is still quite usable. Since I bought it, however, I found that even if fully charged when I shut the laptop down, the battery still runs down in a day or two without it being used at all. No other laptop I've ever owned has done this. I expect the amount of charge to decrease slowly and maybe even fully discharge after a month or so but not in a day or two. If I run the laptop off a fully charged battery, I get a few hours use, as I'd expect.

The fact that the battery goes flat if not used for a few days has never really bothered me that much. I now want to give the laptop to someone else and would like to know if there's a fix for this - assuming anyone else has observed this behaviour.

Thanks for reading.

    Open Control Panel. Search 'button'. Click 'change what the power buttons do' in left pane. Click 'change settings that are currently unavailbable'. Scroll down and UNcheck the box for 'fast startup'.

    I have tried that but didn't seem to make much, if any, difference. Thanks anyway.

    You probably either have a short in the battery pack or its energy capacity is very low.

    Go to the elevated command prompt.  Enter 'powercfg /batteryreport'. Then return to the desktop. Open file explorer. Then search for' battery-report.html' in the c:\windows\system32\ sub-folder. Double-click to open it in the browser. Post screenshot of the first part of the report if possible that compares design full charge capacity with its remaining full charge capacity.

    It doesn't look too bad, considering the laptop is 7 or 8 years old:

    >>>the battery still runs down in a day or two without it being used at all. >>>

    When you plan on not using it for a day or two, fully charge the battery. Then remove the battery and set it aside. Then see how much charge remains the next time you plug it back in and boot up. That way we can see how fast it's self-discharging due to internal leakage.

    Some older machines like your's will run fine on the charger alone without the battery plugged in. So it's possible to test the battery separately and still use the laptop on the charger alone if you have to.

    I've tried that before (and, you're right, the system will run without the battery present). The battery is good as its charge holds up well when it is out of the system. There's definitely something in the system that's drawing current when it's supposed to be off. I've taken a look in the BIOS settings and there's no setting for power to USB or similar, so I think I'm stuck with it.

    Do you have anything plugged into any of the external ports when you shut down including a mouse dongle, external display, lan port, etc?

    Hi @Raichea,

    Did you try to update the driver.
  • Raichea

    No to devices plugged into ports.
    What driver are you referring to, Easwar? I believe all drivers (and the BIOS) are up to date.

    Barring a ground short or hardware problem, the most likely cause is that the Windows version fast startup option isn't compatible with this laptop. The likely fix is to reset the machine from the hidden ACER OEM Windows reset partition if it is still accessible or intact.  This however would mean that the original factory installed Windows version would be re-installed.

    Thanks, for your input. I guess I'm just going to have to live with it.

    Press WIN+R. Enter 'msinfo32'. Please post a screenshot of result if possible.

    MSInfo provides a huge amount of data. Which do you think is relevant?

    That's why a screenshot of the first msinfo32 image might be helpful if possible. I most interested in seeing the right pane.

    Remove battery pack. Inspect battery pack connector and corresponding mainboard battery pack connector. Mainboard connector should have closely spaced gold-plated wire pins. Make sure all pins looks straight with none touching an adjacent pin.

    Pins are all good.

    F2 into the BIOS menu on startup. In the BIOS Main tab make sure the NetworkBoot & Wake on all Networks options are disabled. F10 to save settings and exit. Test battery drainage again overnight.

    Thanks...I'll have to check this out later as I won't have access to that laptop for a week or two.
