HP 15 r-031tu notebook AC do not recognize when, but battery when the costs

Hello

I bought this HP 15 laptop r-031tu about a month ago and I have some very strange power problems:

1 AC plugged in, with battery - battery recharges correctly when the laptop is turned off (LED: solid orange light), but doesn't recognize is no AC when the laptop is turned on (LED: solid white light). Status icon still shows just remaining battery power as if the AC isn't there (and not the "plugged in, not load" case);

2 AC connected, no battery - cell fuels

3 AC unplugged with battery - laptop runs correctly on the battery (no light).

Also, whenever I plug the AC with the laptop running on battery power, the display flashes and the HQ icon changes in "charge" for 1 second and then she goes back to battery mode.

I tried a lot of solutions found on the forum, including the update of the BIOS, hard closed, using other adapters etc but none of these solutions work.

Before you take this phone to the service center HP is there anything else I can try?

Thank you!

All tried, but failed, so I took the phone to the service center and fixed it. The answer:

Problem was caused by something dirty inside the power supply! They cleaned for me and now the laptop is perfectly supported. Kudos for the effort tho!

  • ITunes does not recognize when the Ipod is connected. Help

    I have an ipod classic and only recently (Christmas 2015 day) itunes has ceased to recognize when my ipod is connected to my laptop. However, I know I tried three cables work because the ipod screen shows that it is connected and my laptop opens the file for my ipod, but this does not add to the music on it. How can I my itunes to work again?

    Thank you.

    It's what charge my laptop when I connect my ipod instead of loading of itunes.

    For general advice, see troubleshooting problems with iTunes for Windows updates.

    The steps described in the second case are a guide to remove everything related to iTunes and then rebuild what is often a good starting point, unless the symptoms indicate a more specific approach.

    Review the other boxes and other support documents list to the bottom of the page, in case one of them applies.

    More information area has direct links with the current and recent buildings if you have problems to download, must revert to an older version or want to try the version of iTunes for Windows (64-bit-for old video cards) as a workaround for problems with installation or operation, or compatibility with QuickTime software or a third party.

    Backups of your library and device should be affected by these measures but there are links to backup and recovery advice there.

  • Satellite Pro L20: battery not charge when the power adapter is connected

    Hello

    all advice appreciated.

    I had a Satellite Pro L20 for about 18 months. Recently, battery does not charge when the power adapter is connected. The battery light starts yellow (which means more liberated, I think?), then will both green, the machine sat for awhile. However the ACPI often said that AC is "offline."

    There are two recent occurrences that coincide with this problem, I try to eliminate:

    1. my friends rat chewed by the feeder for pets! Power is Mobile OK insofar as he fled sector - the rat seems to have simply chewed by the outer cover (I see some threads, but I think that is just a shield, although I'm not an electrician).

    2. I put the laptop in hibernation for the first time. That seemed to mess up the system a bit, which was what initially drew my attention to the problem. This question is a bit complicated because I'm under Linux (Xubuntu).

    I updated the drivers etc from windows when I bought the laptop. Never had any problems until now and have been running linux for centuries. Also, I have mainly the laptop the power supply turned off, but do not remove the battery (is that really a problem these days?)

    I obviously need to replace the adapter, but is - it is likely (and how I can check) that the battery was borked until?

    see you soon
    Chris

    First, please check if the other are lit.
    If the AC led and power led are on the adapter sector is ok and it provides the power to the laptop.

    > The battery light starts yellow (which means more liberated, I think?), then will both green, the machine sat for awhile
    If the battery LED is yellow, this means that the battery is not fully charged and if the Green led changes then recharging is caught and the battery has been recharged.

    So I really don t see any problems with the charge process.

    Maybe the battery is old and so you cannot use it for an extended in such a case only the replacement of the battery could help.

  • Dv7-3165dx notebook computer unexpectedly shuts off when the battery is low

    Dv7-3165dx notebook computer unexpectedly shuts off when the battery is low. Even at 17%.

    This gets really annoying, that I keep losing jobs! Before it used to give me a warning and then Hibernate. Now there is no warning and it turns off without saving anything.

    Help!

    The laptop is a year old.

    I already ran the diagonsitic battery and it said the battery was good.

    OK, I think I finally figured it by changing power options, and I think that the way you reset the battery also helped.

    Here are the parameters:

    reserve battery level (this is when the popup will appear).

    10%

    low battery (this is when the low battery action will be performed).

    8%

    critical battery level (my computer would die at this point.)

    7%

    low battery action: sleep, sleep (this customize to your liking).

    battery low notification: on (hold on).

    critical battery action: sleep, sleep (my computer died already in criticism.)

  • While the loop does not stop when the two values are equal using equal to comparitor

    Hello world

    I have a really, really strange bug. I have a LabVIEW VI that change a chain on a power supply. I have a start and a stop voltage and use a while loop to increment the device. For example if I want to scan from 1, 2V to 2.2 V in 0.2 V incremements, the program will end when "The current tension" = "stop the tension." And it works very well!

    However, when I start - 3 V and want to stop to say-0.8 (new in 0.2 V incremements) the program does not stop when "The current tension" = "stop the tension." I checked with the probe close to what should be the end of the race and - 0.8 V goes both of the entries ' equal to ' comaprison operator, but that his can't trigger a real result.

    It's very strange for me. Espeically as if I'm going - 0.8 V to-2 V but decrement of-0.2 V, the program stops correctly!

    I am very confused!

    See you soon!

    The second thread is particularly relevant. This discussion was 2009, but you can find that the same "bug" being reported to enter the end of the 1980s.

  • SK2061: The wireless keyboard will not connect when the PC is turned on.

    My problem is, when I start the PC, (HPK-15 500, 319NA), wireless (SK2061) keyboard, does not connect. I have to shut down the PC so he can connect (no restart, you must stop it).  Have had the PC for 5 months and it has been published. Not changed the battery makes no difference.

    The internet statement States I shoud push the blue button until the USB receiver flashes. This PC does not have an external USB receiver, I guess it's built in! The mouse works OK.

    Hello @JimCar82,

    I read your post on how the wireless keyboard will not connect when the computer is turned on, and I'd be happy to help you in this case!

    Re-connect your keyboard to your desktop computer wireless, I advise you to follow the steps described in this document on the keyboard and wireless mouse troubleshooting. The USB receiver should be found at the back of the tower.

    Please re-post with the results of your troubleshooting, and I look forward to your response!

    I'm so when I tried to import data to test data access error

    and in the error log saying his request does not exist

    Couple of solution to try

    1. recreate the import format and then reload again as sometimes get corrupted as well.

    2. place an excerpt from the sample of data to load into the Inbox and see if it load successfully.

    3. the account that you use to connect to SQL must have read access as when Bulk Insert is used, FDM creates two temporary files, which is the .tmp file referenced in your error message. The .tmp file is an insert in bulk. In order to run an insert action block in SQL, FDM uses the network account that runs the MSSQL Server service. Account goes off in the Inbox of FDM, reads the file and them slap it in the database.
