• Presario CQ20-320TU: my notebook (presario CQ20) directly turn on when I plug in the power cord without battery

  My laptop (presario CQ20-320TU) turn directly every time I plug the power cord without battery. What is the solution?

  Hi there @emonsonjaya,

  Welcome to the Forums of HP Support! It's a good place to find the help you need, so many other users, the HP experts and other members of the support staff.

  I understand that your notebook is turn on/off automatically when it is plugged. I'm happy to help you.

  I would recommend that you look at your BIOS, especially in power options and check if your BIOS has a setting option on automatically. If yes it change at your convenience.  Another option would be to update your BIOS and see if that solves it.

  Here is the page of support for your model and, if necessary, give it a try, it will automatically download the file if you click on the link. You then need to run the executable file of your current download folder.

  If you are having problems with an update of the BIOS, you can always restore it, using the following:

• Whenever I have turn off my laptop and turn it back on, all my data disappears.

  I'm using a thinkpad notebook issued by school (lenovo R400) that uses Windows Vista.  I know almost nothing about computers, but a couple of my friends know a little, and none of them were able to help me.  Every time (it happened three times) I turned off my laptop in the last three months or so, I turn it back on and everything disappeared.  I downloaded programs, backgrounds, music, documents, photos, videos - all of this.  Now, I checked the recycling bin, so I know that it has not been deleted.  Also, if I check what has changed recently, I can recover some of them.  I usually just let my laptop to sleep, so I turn rarely completely off.  The first time it happened, there were just two Documents folders, two folders of music, etc.  The next time it happened, they disappeared, but they have either finally came on their own after a few days, or me just messing them back.  As I am currently in College, it is very important that I can access everything I could have written this year.  It is a big problem for me, so any help would be greatly appreciated.

  You are constantly thrown into a temporary user account. This can be caused by hardware or malware infection problems. The most sensible thing to do is to take the machine to your school IT Department. and let them take a look. MS - MVP - Elephant Boy computers - don't panic!

• 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.

  Hello

  You want to turn off wireless and Bluetooth via the BIOS, I suggest you ask to contact the manufacturer of the computer for that.

• Two problems that seem to be related. The screen turns off suddenly and reappears when the mouse is clicked. At the same time, the cursor insertion point disappears.

  The cursor disappears during the strike. It is blackened and cursor disappeared three times during the typing of this sentence. Very frustrating! I'm running Windows 7 Pro on a Dell Inspiron.

  Hi Ed,

  Thanks for posting your question in the Microsoft community.

  I understand that you have 2 problems on your Windows 7 computer.

  1. The screen turns off when you click with the mouse.
  2. The cursor on the screen disappears while typing.

  Let me know if this interpretation is erroneous. To better understand the issue, let me ask a few questions.

  1. What is the brand and model of the computer?
  2. You did changes to the computer before the show?

  I am here to help you and I suggest these methods to solve the problem.

  Method 1:

  Start the computer in safe mode and check if the same problems occur. Safe mode allows only a minimum set of services to load, this will help us to know if a service is causing the problem.

  Startup options (including safe mode)
  http://Windows.Microsoft.com/en-us/Windows7/advanced-startup-options-including-safe-mode

  Method 2:

  If the problem does not occur in safe mode, and then perform a clean boot, this will turn off non-Microsoft services and therefore to determine if any non-Microsoft service is causing a conflict for the problem to occur.

  http://support.Microsoft.com/kb/929135

  Note: once the diagnosis is made, follow the steps in the article to configure the computer to start the Normal start.

  Method 3:

  The question could have occurred because the drivers on your computers are not updated. See the link, follow the steps and update the drivers.
