My Windows 7 laptop turns off when I disconnect, even at 99% remaining.

If I unplug my computer, laptop or if I go back to hibernation, I get a battery warning and a minute later, the computer goes to sleep. The thing is, the sensors and the battery are very good... before you close the power in the taskbar icon shows "99% (3 hours) remaining" and once I got back on it lasts for hours, as it should. I went through all food and settings options I can find, but no chance to resolve this. What is going on?

In addition, this might be a clue... Windows Aero is disabled when I turn on the computer, and the typical ways to reactivate, do nothing. They show it already on, and at the back of switching is futile.

The problem might be in the way that Windows sets low and critical battery levels.

I had the same problem and I checked the settings of 'Battery' under power options > * plan name * > advanced settings >.
I put my low rate and critical for 20% and 5% respectively.
Hope that helps!

    You have the screen image out to another monitor (one that is not plugged in fact). How you pass to the internal laptop display varies, but most cell phone companies make a combination of keys, such as Fn + F6 or something.  Looking for a symbol that looks like a monitor.  It is usually color coded and requires activation of a Fn key.

  • HP 15-r011na: laptop turns off when it is attached cable ca

    Hi, I recently picked up the upgrade of Windows 10 and since then have had problems with the laptop switching power, do not know if it is related to Windows 10 but seems a coincidence!  When I got close I use the power on the screen completely closes the button and the laptop.  When I turn it on it's ok, if I have the AC cable disconnected (i.e. using battery power) but if I have the AC cable the screen goes off, but then goes black and seems to have turned off again, and I have to press the power button to put on the.  Also, if I connect the cable so that the laptop is on it goes black immediately, and if I delete it the screen comes alive again.  Can someone tell me what's going on that I have no idea about these things, and it makes me absolutely crazy!  I would really appreciate some advice please.

    Hi @Greenjack67 ,

    Thank you for visiting the HP Forums! A place where you can find solutions for your problems with the help of the community!

    I stumbled upon your post on the laptop and wanted to help you! I looked in your question about your laptop 15-r011na HP TouchSmart and the laptop turns off when it is attached cable ca. Here is a link to test and calibrate your battery for Windows 10.

    Note Remove all USB devices. Disconnect all devices of non-essential, as these can cause some problems.

    Plug the power supply directly into a different wall outlet. Do not connect it a power strip, surge arrester, or secondary power source as this could cause and issue.

    You can try to use the Windows Update Troubleshooter to fix updates that do not come through Windows 10.  Please restart the laptop twice to make sure that all updates are completed!

    Here is a document that shows how update the drivers that do not work correctly with Windows 10.

    I hope this helps.

    Thank you.

  • Laptop turns off when the lid is closed

    Since yesterday, my Dell laptop randomly started shooting (sleep/hibernate but not stop) whenever I tried to close the lid.  I already checked my power settings and they remain unchanged.  I tried to do a system restore to a time before the problem began and tried to uninstall the driver from device (with a similar question in this forum).  Nothing has done so far.  The computer seems to work normally otherwise.

Finally I discovered that the drivers installed for my adapter DVI to USB causes the problem. When I uninstalled the drivers, my computer began to behave normally.

  • Computer user connection laptop turns off when the lid is closed

    How can I configure my laptop to disconnect the current user (switch not only users) and force them to close all programs when the lid is closed, and then switch to sleep mode?

    There is no direct option for this, but you can create a batch file that has orders for logoff, then the command for the night and have that run the trigger of "Lock Workstation".

    Task Scheduler allows many triggers.  Type Task Scheduler in your Start menu, and then click New task on the right side to explore your options.
  • Windows 8: laptop turns off instead of going to sleep!

    Hello

    Earlier, everything was going well but over the past 10-15 days, I am facing a problem.
    PROBLEM: Whenever I have press the power button / stop or try to put the pc to sleep, it shuts down the screen but hard drive and other things stay active... and after 2-3 minutes it shuts down my laptop completely. So, I have to start my laptop instead of awakening it.


    I have configured my laptop for the following measures:
    1 power button
    2. close cover
    3 icon pressed sleep I have start menu
    4 sleep after 20 minutes of inactivity.

    For all of the above-mentioned actions, pc should go to sleep which does not occur. Please suggest me something.

    Hello

    Keep the computer in a clean boot state, and check. If everything works well after a clean boot, you can deduce that some third-party services are at the origin of the problem. Continue with the remaining steps to pin-point on the third party service. After find you the program that is causing the problem, you will have to perhaps to update or install a newer version of the program, if you rarely use that you should consider uninstalling the software.
