Question about HP Pavilion a810n (PP164AA) PC Desktop

1 Answer

Monitor reads: PC entering power saving mode then shuts off;PC on

Monitor reads: PC entering power saving mode then shuts off Pc still running (HP pavillian 2700 ghz 1gig ram). It started out by the cpu saying, Fatal Error, I think, then it said Power Surge. Then everything froze. I shut off cpu then started it up and monitor says pc entering... I used a old Emachines cpu that has windows 98 and I plugged it into the HP monitor and the monitor was working good; so I know the cpu is the problem. I unplugged the Ram Cards I have 2 512 mb cards. I took out the battery then reboot nothing. The fan is running but the cpu sounds like its in a higher gear than usual. Can I transfer files if I get a USB plug to connect it to another cpu then plug in my flashdrive 8 gig and transfer my pictures, music and programs to the flashdrive? Or do I have to take out the hard drive and put it inside the Emachines CPU but then I'll have to take the hard drive out of it too. Sounds like alot of work. Has anyone had this problem and found a solution besides sending it too the GEEK SQUAD or a local cpu tech who will probably copy all your files and programs? Or maybe put some spyware in the cpu. How long will this take to fix? My problem is I don't trust anyone I wanna see what they're doing. Can u help I would really appreciate it. Thanks. :o)

    Can you be more detailed about resetting the cmos battery? When you say jumper is that a connector plug that is in the cpu that i'm suppose to unplug and put it in where u say? What is rtc? So take the battery out or leave it in? Thanks for the help.

    I did what you said and nothing. Same problem. Should I buy a new power adapter to see if thats the problem or should I open it up and try to fix it? Then again it could be the motherboard. Can you help? Thanks again.

    The fan is on and is the one on top of the heat sink processor.

    I get the same msg: pc entering power saving mode.

    All power plugs are plugged in.

    No beeps.

    All I here is the fan the processor light does not come on (amber/orange color). My power light (green) is on once I plug the main power cord to the back of it. It did make a weird static sound today like a bizzit sound.

    I don't see a blue or green light in the motherboard I dont remember ever seeing one when I installed the 512 ram.

    I will hold down the power button for a couple of min like u said. Thanks.

First do not take the hard drive out and put it in another computer. It is configured to run in the computer it's in.

Next, you probably did have a power surge either from your power supply or the power in your home. It sounds now like your power supply is damaged.

The processor does not have any gears; the sound you hear is most likely the fan in the power supply running too high.

Taking the battery out does nothing unless you move the jumper on the rtc to clear the CMOS. You should do that. You will have to get the computer running before you can transfer via USB to a flashdrive.

Unless you know what you are doing, you can ruin your computer just by touching components or the motherboard. You need to ground yourself first and make sure the computer is unplugged from the wall.

Here is what I recommend:

1. Get a grounding strap and hook it to your wrist and something to ground it. The package will tell you how.

2. Open the computer case and move the jumper to the proper location to drain the CMOS. (There will be 3 pins, and it will be on two of them. To ground it move the jumper to the uncovered pin and the one next to it. Leave it there a minute then remove it and out it back on the other two.

3. Be certain the two sticks of ram are properly inserted all the way in the slots; do not use brute strength.Leave the side cover off, and plug the Computer back in again. You should see a light come on after a few seconds. You should also see the power supply fan on.

4. Turn on your monitor and then boot your computer. If it comes to a screen that says it stopped abnormally, choose the last known good configuration.

5. you don't get that far you have worse problems, namely the motherboard or the powersupply. If it boots you should also hear the hard drive whirring.

If you can't get it going let us know. But one thing I'd like to convey to you. There is nothing in your conputer any reputable technician in a good shop will want. Neither will he put malware on your system.

Good luck!

    Sorry to not get back sooner. The RTC is on the motherboard usually near the side where the case side comes out. It isn't' far from the battery. A jumper is a small plastic "cap" 1/8th" wide by perhaps 3/16ths, and it closes contact between two of the pins on the RTC.. If you look closely near the edge, you'll see RTC printed (or if you have a manual you can see exactly where it is).



    There are almost always 3 pins in the RTC, with the jumper covering the middle and one outer one. Make sure you computer is unplugged, there is no light inside on the motherboard, ground yourself by touch bare metal on the frame of the computer, and pull the jumper off the two pins it is currently on. Place it on the outside bare pin and the middle, and leave it on for about 30 seconds.



    Most folks will tell you to also take the battery out too, for about the same time. This clears the information in the CMOS so that you can have a fresh start. Put the battery back in, move the jumper to its' original position. Try plugging it back in, turning on the switch in back, and boot it up. I would also tap F8 key until it says it is entering setup.



    Then you can look near the top of the screen and choose "load defaults". Exit and save. Hopefully this time it will boot up. Good luck, and write back if anything isn't clear.

    This is a tough problem. There are several things that could be wrong. Answer these questions for me and we'll start.



    1. When you plug it in and turn it on does that fan still come on?

    Is it the fan on top of the heat sink on the processor or a case fan?

    2.. Do you still get any kind of message on the monitor at all?



    3. When you removed some of the parts did you unplug and of the power supply cords from the motherboard? There should be two, the big obvious one and another near the back that will have normally 8 pins, but could be 4. If that second one isn't plugged in it will not boot.



    4. Do you get any beeps when you turn it on?



    Is the hard drive turning and making a whirring sound.?



    Do you see a small green or blue light near the back side of the motherboard? And is the power switch on the back of the computer turned on?



    There is nothing in the power supply that you can fix. You can also try pressing in ob the start button and leaving it pressed in for a couple of minutes. Check these things out and write me back.

SOURCE: SPYWARE ON COMPUTER

Hello there.

I would first try scanning the computer your self. Please click here to start a free online web-based scan of your system, this looks for virus, trojan, spyware infections so should hopefully clean your system. Once the scan completes it should prompt you to remove anything found.

If this doesn't help then yes take the system back to where you purchased it for support. Make sure you backup your files first.

Hope this helps.

Monitor displays "warning pc entering power saving mode


Hello
Sounds like to power settings were set too low. Restart the PC, before it gets to Windows press F8. This will send the PC into SAFE mode. You'll get a menu of which SAFE mode to select, just select SAFE mode with networking. Once in SAFE mode, go to START, Control Panel, Power Options. From there select new settings. Since this is a desktop, I would make the settings very long. Good luck

Dell Monitor shuts down with "entering power save mode" command


There are times when you need to install software for a monitor to work with a PC. If you have the software disk that came with the monitor, you can try to install. You can also try changing the power cord to the monitor. Generally, power cords for PC's and monitors are the same. If you use your PC power cord and the monitor comes on saying that there is no connection with a computer, and it was not doing this before, you can get a new power cord for the monitor. If you can, try the monitor with another PC or laptop to rule out a bad monitor.
I hope these suggestions have given you a place to start and that they were helpful.

My monitor shuts down after one second.


Dell monitors automatically go into power-save mode after a preset amount of time when the computer is inactive. The Dell monitor will go completely black, instead of showing a screensaver. This doesn't mean that your Dell computermag-glass_10x10.gif has shut down. Instead, this allows your monitor to essentially turn off until it's needed again. You can change how long it is before the Dell monitor goes into power-save mode by changing your display settings.
  1. Step 1 Press any key on your keyboard or move your mouse. Either will turn off power-save mode. Alternately, you can press the power button on your Dell computer tower or laptop.
  2. Step 2 Press any key a second time if the monitor goes from power-save to stand-by mode. Stand-by mode allows the screensaver to appear.
  3. Step 3 Enter your user name and password into the login prompt if your computer requires a login. Press "Enter" to begin using your Dell computer.
  4. Step 4 Change the display settings on your Dell monitor to prevent your monitor from going into power-save mode prematurely. Right-click anywhere on your desktop and choose "Properties." Click the "Screensaver" tab and press "Power." Beside "Turn off Monitor," choose a time amount from the drop-down list and press "Apply."
