System goes to sleep when spacebar is used

a very old 2007 made PC. (relic)
THAT MEANS THE CHIP DRIVERS ARE DEAD, MISSING,WRONG OR INFECTED.
the power button ends sleep to if pushes for 10 full seconds and released. if yes, chip drivers are wrong.

no oS told at all we can not guess your OS , real.
I can tell what it had new. but gee most PC were upgraded the OS
XP PC and came with VISTA READY, promise, DAY1. new
so get your missing drivers at HP.com
using your service tag #
if you google for them you will get a VIRUS, all things XP;/VISTA
in the wild (means not HP.com) are fully infected,

cure #1, the omg simple cure, is turn off all sleep modes
and use the power button to shut it off if done.
this is a hide the problem cure.
the real cure on all PCs on earth is good drivers from your OEM
called HP.com
omg came with Office 2003, day 1.

sleep modes,(all) fail if drivers are bad.
it's a classic problem.
fol sure caused buy.
1: not using plug and play to all drivers in device manager and getting them all good.
2: upgrading the OS to w7 and there is no support for w7 here.
3: loading infected drivers, not from HP.com. oops you did that.?
4: MANY drivers must be good. , USB, GPU, and CPU and all bridge chips, , if any thing in device manger is wrong (view + hidden)
that be wrong. and is the cause. #4 is not looking here first.

Sounds like your keyboard is sending the wrong signal (the one telling your PC to enter sleep mode) to your motherboard when you press space key, which (if true) would indicate it's faulty. It could also be you've contracted a virus and is playing a particularly nasty practical joke on you (let's hope that's all it does). Try connecting another keyboard to your PC and see if that helps. If it doesn't, then you'll need to clean your computer of any viruses. Try also disconnecting your mouse and see if that changes anything. If your keyboard comes with a shortcut utility software for it, run it and check there's no shortcut set on your keyboard's space bar. You've additionally specified you're not using wireless keyboard, but could you also please write what OS you're on?

Control panel > Power options > Choose power plan> set to Never turn off display / Never put monitor to sleep
(For Vista... XP similar) Not sure about Win 7, will not be much different

DVD Issues, possibly the media being used, only real way is to try another DVD drive in the tower

- your comp is in hibernation mode
- go to control panel>>power management>>put to NEVER the sleep mode,hibernation,HDD,battery
- restart system

Hi there,

Normally when you put your computer to sleep with your keyboard you only have to press a key on the keyboard to wake the computer again.
I normally use my spacebar to wake my pc but any key should work fine.

Kind regards!!!

Hello,
You can reboot your HP Pavilion, and while rebooting go to BIOS by constantly tapping F1. And then there has to be an option which you need to enable "Wake up by Space bar" option. Once you enable the option, save the BIOS settings and then try whether the issue persists or not.

You might have to remove the tiny switch that is under the Right hinge. Your laptop thinks that the top is still closed. Just remove it and cut the two wires. Closing the lid won'd sleep the PC anymore, so be sure to hibernate before closing the lid.

I have an hp media center that runs windows xp with service pack 3 and my monitor is an hpL1706 monitor and was running fine now it says no input and goes into sleep mode how do I fix it?

Are you using an optical mouse? If so, try turning it upside down before entering sleep mode. On some surfaces (with some mice only), the mouse picks up movement even if perfectly still.

The setting is controlled by your computer not the monitor. I'm assuming you are running Windows - open the Control Panel (from the Start button) and go to Power Options. You can find it in here. If you have problems, get back to me with the specific Operating System you are using and version or service pack level and I can give you more specific details.
