Solved ASUSTeK Computer Inc. K54C 1.0 Power Problem

  • 0

How do I disable the pop up that pops up almost continually in the center of my screen telling me that the power source is switching back and forth between AC and the battery? How do I know if it really IS almost constantly switching back and forth, and if it really is, how do I stop it?

  1. re: “How long does it run on battery, before Windows dies (it usually goes into hibernation before battery power hits zero)?
    Some battery faults don’t allow proper monitoring of charge status.”

    Not long at all. 5 to 10 minutes at the most. The battery symbol barely shows any sign of use — like maybe its down 10% at the most before it starts that pop up again. If I plug in the adapter at that point the pop up still keeps going until the battery reaches a full charge again — usually about 15 minutes. After that, I can use it with no pop ups until the battery gets down about 10% again. Rinse and repeat.

    1. Is that 5 to 10 mins with the mains disconnected. What happens if you don’t reconnect the mains. Does the laptop die suddenly after that?

    2. Does Windows produce a warning bubble in the Notification area. Does it hibernate or die suddenly before it gets the chance to.

    If the latter, the battery is at fault.

    If mains powered and all is working as it should, you shouldn’t get any battery warnings unless the battery is faulty.

    That popup displayed in the video you posted here, isn’t a Microsoft/Windows popup.
    It’s from additional software that Asus have installed.
    There maybe something related to this if you hover around the Notification area, down by the clock.
    (You may have to click on the little arrow to show everything that’s running down there. Better still; r-click an empty part of the taskbar/Properties. Under Taskbar tab, select ‘customise’. In the pane now showing, bottom left of this, put a tick in the box; ‘Show all icons etc’ ).

    Now you can see at a glance what’s running.
    Hover around them. One may be related to power/power management or similar. This is likely the Asus-added tool. Clicking, or whatever, may reveal various options.
    You may be able to disable it.
    If not, open CCleaner (I assume everyone uses this), Tools/Startup and see if the power management software is running at startup. If so, click on the entry and select disable. It should be disabled next time you boot up the PC.

    Probably a ton of other stuff in there you could also disable, but that’s another subject.

    Windows has its own built-in battery warning system. As you know, battery status is the little power bar and two-pin power plug icon.
    When battery gets low (down to 10% capacity(?)), A small warning bubble pops up in the notification area. If it gets below this (providing the battery discharge isn’t catastrophic) Windows will automatically go into hibernation.

    This may not operate correctly with a faulty battery.

    My gut feeling is that you have a duff battery, but it’s an expensive item, especially if the diagnosis is incorrect..

    In summary:

    See if you can disable the ASUS battery/power notification software, either from the taskbar, or if present, by removing it from startup.

    Windows itself should then notify re battery status/low power warnings.
    (Small bubble message near clock).

    It should run ok on mains, without warning of battery probs, unless battery is faulty – possibly a shorted cell.

    Just an additional point: Re WIndows power status symbol
    (the mains plug and battery icon).
    When running on mains, does the 2-pin mains icon remain constant or disappears for brief periods?

    Apologies for the rambling and some repetition. My brain doesn’t function too well these days.
