computer laptop HP compaq 6730 b freezes and slows down

I have a laptop hp compaq 6730 b.

Since a few days, I realized when I plug to charge my cell phone, it freezes finally and slows down.

The CPU usage suddenly increases.

What should I do?

help please...

Thank you

It works ok with only the power adapter is plugged in and the battery out of the laptop? The battery charge ok if the laptop is turned off? The laptop works for a long time reasonable with just the battery?  I've seen this kind of problem with a Toshiba machine that used a NEC/CATHERINE 0E128 Proadlizer high switching frequency DC/DC Converter output capacitor.  I doubt that your computer has this chip but the problem and the function are similar.  It is a device surface and can cause the laptop to have a problem with the battery and the power adapter plugged in at the same time.  Many times this you will also charge the battery when the computer is turned off, but not when it is turned on. Sometimes it will not allow your to run Notepad with only the attached power adapter and the battery removed. Just to think.

    Hello

    I suggest always back up your personal files, etc. before you try the following procedure.

    Shut down the laptop.  Tap away at f10 you start Notepad to open the menu of the bios.  Under Advanced Options or diagnosis tab, you will find the possibility to run tests on the hard drive and memory.  Post back with the details of any error message.

    If the criteria above, try the following.

    In the Menu start, open the all programs, open accessories, right-click on command prompt and select "run as Administrator".  In at the prompt, type the following command and press ENTER.

    sfc/scannow                (Note that there is a space between sfc and /)

    Let the entire process, then the output type and press ENTER.

    Then, click on the Start Menu, click computer, left click Local disk C once to highlight, right-click Local disk C and select Properties.  Click the Tools tab and then click on the button "check the drive for errors.  In the next window make sure that both boxes are checked, then click Start.  Right plan the audit on the next reboot of the system, and then restart the laptop - this process can take several hours before the load in Windows.

    My HP elitebook 6930p who basically has the same hardware as you ran W8.1 very well.

    He also ran the first 2 preview W10 relies very well.

    All versions since that time, the ricoh cardbus controller then gives an error code 12 (resources).

    I reported this bug to MS and I noticed there were other models HP affected as the 8440p.

    So, unless this bug is corrected and that your machine has the same Ricoh card reader mine, you can probably count on getting the same error.

  • Computer laptop HP Compaq 6710 b - NTLDR is missing

    I'm having a problem - from the beginning.  I don't have a recovery for this computer cd.  I turned it on and when he started start-up he began to start in console recovery with a count down. Then he started in windows and I thought either and played a few games on it and looked at files, etc.  I made a stop "correctly" and then a few days ago and I turned it on and I kick it to me stand in the collection with the count down and then NTLDR is missing appears.  I tried several times to restart the unit, and nothing is done, it does not start in the operating system. Or it will start without failure or anything else.

    I used a Seagate Disk Wizard utility CD to format the hard drive and run tests.  Now when I try to do a fresh install of XP PRO, it runs through the loading of files, drivers, etc..  When you get to the part of installation a blue screen appears and says that Setup did not find hard installed on the computer disc units. That the installation cannot continue.

    I know that when I did the tests on the hard disk drive of utility Wizard showed that hd was located "unknown controller" rather than the motherboard controller.

    The messages screen also says to make sure that any hard drive is turned on and connected to my computer and that any hardware configuration of the drives is correct and it may involve a manuf. - supplied diagnostic or Setup running.

    According to HP, this system has a SATA drive.

    You have to enter the BIOS and change the configuration of hard drive to something which may include installation of XP.

    I don't know exactly how on your system, but here are some notes that I have to put you on the road and maybe someone else will tell you exactly what you need to do:

    Looks like you need enter the BIOS on your system by pressing the 'Delete', F2, F10 or F12 key (what the key is good for your system), find the section where the types of hard disks and hard disk interfaces are configured and temporarily change the setting so the XP installation is able to find the hard drive.

    Where to find the accommodation and how to change depends on your system manufacturer and the version of the BIOS, so you end up having to look at her.  If you know your system brand and model, we can probably help you find a job.

    You must locate and change the interface mode to your hard drive in the BIOS so that when installing XP loading, it will be able to locate the hard drive.

    Before making adjustments, you should take note of what are the current BIOS settings, so you can change when you are finished.

    The adjustment varies so here are some examples that I have accumulated:

    The adjustment is done in the BIOS and could be in Integrated Peripherals, Configuration of SATA, SATA Mode device.  After you make the changes, save them and restart your XP installation program.

    If you find that the mode is set on the RAID/SATA mode, change the IDE mode.

    If you find that the mode is set to SATA, change the IDE mode.

    If you find that the mode is set to SATA, SATA mode off.

    If you find that the mode is set to AHCI, change the ATA mode.

    If you find that the mode is set to AHCI emulation Mode, change the IDE emulation mode.

    If you find that the mode is set to SATA, SATA mode off or change the ATA mode.

    If you find that the mode is set to SATA Native Mode, disable the native SATA Mode.

    If you find that the mode is set on AHCI/RAID Autodetect, change the combination mode.

    After completing the settings, ACCEPT and SAVE changes and reboot the system and see if the configuration of the installation works properly now.

  • Computer, speed up and slow down

    Hi smileyboy,

    Fans generally increase speed (assuming you have a temperature fan control chip) when the inside of your box reaches a certain temperature. Once the heat has been dispated the fan speed will reduce again. This is what normally happens. If the fan speed is monte and descends without particular reason so it could be the chip temperature is causing the problem or the fan may be faulty. anyway a repair technician would need to watch it.

    Before you do this, however, try to open the case. I guess that we are talking about a desktop PC? If it's a laptop take it to a repair shop, access to the fan in a laptop is quite difficult if you don't know what you're doing. As I said, if it's a desktop computer, remove the side panel (initially with the machine turned off - remove the plug of the power supply and the rmemeber to yourself before you touch anything inside the Earth). Now look at the fans. Is there an accumulation of dust/dirt on the fan blades? If so gently brush the dust with a small artist, own brush. Check also on the processor heat sink. If dust has accumulated in the heat sink tips then purge with a can of clean air. Try running the machine with the cover to see if additional air flow solves the problem. Your PC may be overheating causing the fans speed up to cool thing down. Listening to the fans to see if you can isolate which fan is the source of the problem. You'll have a fan on top of the CPU (porcessor); You can also have a hood on the back of the case. Another fan is located in the power supply (power supply). Power supply fans, however, must be examined by a qualified technician.

  • Wmplayer.exe in list of logon process and slow down my computer automatically

    Hello!

    All the minutes (and it can happen several times in a minute or two, then accompany minutes nothing happens) my mouse freezes and my computer "thinks" for a few seconds, as something that four-color or trying to open, only nothing is.

    I opened the Task Manager upward and looked at the list of processes, and "wmplayer.exe" opens and closes during this period.

    I found this problem in the Windows 7 forums, and that's exactly what I saw, only when running Vista and NOT 7.

    Edit: I did a few things. Originally, before the beginning of the process, I changed USB ports of the just in case, mice that did not work. I did several tests and checked the registry for a particular worm that seems to mimic some of these symptoms. I tried to open wmp to see if it is open it would attempt to run, which he did not. I also deleted the plugin Firefox wmp in case that is the question. None of them helped.

    Edit again: I took the step on the reference station and did a clean boot. This does not prevent the problem. Wmplayer.exe has always arisen as I explained above.

    Any ideas? Thank you!

    Hello!

    Just an update for those who have this problem.

    Nothing above helped at all. I had several people look at the computer, had many suggestions from different people, went up to remove wmp and synchronization of the computer, but nothing helps. I always had this problem.

    On a whim, a few days ago, I decided to try to buy a new mouse. Couldn't hurt, right? :) And here, I have not had the problem since. Try a new mouse! Worked for me.
