HP8300 - green light flashing on the motherboard and PC do not work

Hello

yesterday, I changed the power supply of my HP 8300 with a new office.

the computer has been disconnected from a week of power supply (230 VAC).

Now it does not work when I press the Start button. No noise, flashing on the front.

On the motherboard there is a green led flashing (close to the led, there are 2 Word: to THE and CATERR #).

I tried to change the power cable. No change.

I tried to remove the RAM. No change.

I've read other post on this forum.

What is the small battery on the motehrboard? Can I leave the pc connected to the power supply, or did it damage?

Thank you

    Hello team,

  • Flash in the last nightly build is not working and causing accidents. Help?

    I use an Asus Transformer tf101. I updated today every night and now flash does not work in the program. Once I try to play any flash video, the program crashes and it blocks once or twice more after that before so I can use it again. I deactivated all my plugins and cold booted but in vain.
    Another question, that I have, is that it freezes sometimes on the homescreen at startup. This instance occurs usually after that I try to type an address or use a bookmark. The only way I found around her had to press one of the three icons top site first. Does anyone have a solution to this?

    Edit: I started the previous generation at the moment. It is not as nice as the style of the most recent version, but it plays better than other mobile browsers out there flash video. As a break, jump before or put the video in full screen, the controls are always hit or miss.

    This is a known issue with the current nightly builds. We hope she will rule early next week. I don't think Aurora builds are affected by this problem. http://www.Mozilla.org/en-us/mobile/Aurora/

  • Cursor flashing at the start of the system and hard drive not working do not on the other computer

    Original title: I need help with my Hardrive

    Recently I had problems with a hard disk of computers. So I'm going to give guys the full story, I fell on this computer, it's actually my mums computer and it had a blue screen at startup error. I'm sorry, but I don't remember that the error was called on the top of my head, basiclly I quikly searched online and alll they say should use fixboot. So I did and the computer booted Windows XP very well. So the next day, when I was starting the machine (just to let you know, it would be the first start since I used fixboot, other than the right after that, I don't know if it would make a difference).

    In any case, while trying to start, there was just a slider, or as underscore that retain just flashing in top left corner. I thought that maybe I should reinstall windows on another partition so my files would be safe. I did it, the installation program had no problem with it, but when I booted up I got the same line of flashing underscore / cursor in the upper left corner.

    I thought that maybe I should back up the hard drive using my other computer so I tried to plug in the hardrive in my work computer and the hardrive started to heat up and as if it worked but any hardrive was getting into my computer, I refreshed it, started the computer upward once again, nothing.

    So my question is what is the problem with this hardrive and how I save? I'm ready to do anything, use the live CD, using another computer. I have precious moments of family on the hardrive.

    Thank you guys

    Hi Joemost,

    As you have important data on the hard drive. We recommend that you contact the vendor of hard drive to diagnose hard drive or visit the nearest tech store to save your data.

    There are chances that the boot files are missing on the computer and also you could have not connected the hard drive as a slave when you connected to the other computer. Once you have saved the data, you can repair the existing windows and check if it starts successfully.

    Try these steps to repair install Windows XP:
    a. start the computer using the XP CD. You may need to change the boot order in the BIOS OF THE system for the CD starts before the hard drive.
    b. on the "Welcome" screen, press ENTER to start the installation of Windows.
    c. accept the license agreement and Windows will search for existing installations of Windows.
    d. Select the XP installation you want to repair in the list, press R to start the repair.
    e. the installation program copies the necessary files to the hard disk and restart.  Do not press any key to boot from CD when the message appears. Setup will continue as if it were a clean install, but your applications and settings are preserved.
    f. when the installation is complete, check if Windows starts correctly.

  • ReadyBoost - tab is missing in the properties, and it does not work!

    Title says it all. When I insert a disc and the Autorun dialog opens, if I click "Speed up my system" it just opens the property page for the device with the free space, etc. The ReadyBoost tab isn't there.

    I especially don't think that I NEED, I'm 64-bit Windows 7 Home Premium with 4 GB of RAM. But this isn't the point, please do not answer with "you don't need, so don't bother. All I see is that is not a feature that is supposed to be there, if I need it or not, it could indicate a bigger problem with my PC.

    Where the ReadyBoost tab? I know in Win7, the service is incorporated with Superfetch, and I checked this service is launched and automatic. I tried to format the USB key as each file system and also tried the switching device to "Optimize for performance" etc. Nothing. I ran "sfc/scannow", and he found no problem.

    Any help guys?

    Hello

    ReadyBoost in Windows 7 is much better integrated and provides even better than Vista speed.

    ReadyBoost still help your performance if you run a lot of memory intense programs, run a
    many programs in the same time, or use some that access large files. In Windows 7 there is none
    upper limit of the amount of memory to use for ReadyBoost. In Vista, it was limited to 4 GB.

    Turn ReadyBoost on or off for a storage device

    ============================================

    Start - computer, or Windows Explorer right click on the drive - properties - ReadyBoost
    tab will indicate IF the drive passes the test of ReadyBoost.

    The problem may be with the USB key you try - it might be too slow. Several USB thumb-
    readers have a bit of fast memory, and then the rest is much slower. Some of them will spend the
    ReadyBoost speed test but does not work properly. If a player does not have speed ReadyBoost
    test then ReadyBoost will not even an option.

    DON'T GO OUT AND JUST BUY A READER WHO CLAIMS THAT IT IS READY - READYBOOST
    many of them are or stretching at least the truth. Look at the sides of the player below and buy
    a you know is FAST.

    Don't forget that the readyboost max cache is 4 GB for Vista and unlimited in Windows 7. If your
    device is 4 GB on Vista, you can use the rest for storage. In Windows 7, you can
    Use any space not reserved for ReadyBoost as storage device. And you need a fast reader.
