My laptop screen goes black after being idle and will not come back on. The computer is still alive and responds to commands, but the screen will not come back on. If I hit the function key on the laptop, it will enter Standby and then I can hit the power button to wake it up and all is good again. Can't be a hardware problem because the screen looks fine as long as I am using it. What could be causing this??

first of all verify your display panel Is it Alive or not

Return the laptop, HP has a history with motherboard issues.

Most probably the SSD have died and needs to be replaced, check with a technician

do a Sytem restore to an earlier Restore Point:

Start the System Restore Utility at a command prompt

1. Restart your computer, and keep tapping F8 during the initial start-up until you get options, select Safe Mode with a Command Prompt then press enter.

2. Log on to your computer with an administrator account or with an account that has administrator credentials.

3. Type the following command at a command prompt, and then press ENTER:

%systemroot%\system32\restore\rstrui.exe

4. Follow the instructions that appear on the screen to restore your computer to an earlier state.

Look for the most recent system checkpoint created before the errors to restore from.

try checking for updated drivers for your hd 5730. i have seen this in desktops with both ati and nvidia gpus.

While you are trying to boot up, before the Windows logo comes up, start tapping the F8 key on your keyboard. Then try to use the option "Last known good configuration". If that one does not work, try to go to the safe mode option

Must be common problem. Linux is the operating system

yes you just lost linux, it needs re-doing but with an external CD ROM drive unless it has a partition
for recovery in which either F10 key will do it or another key check the manual for RECOVERY of operating system its not a big problme but it takes few hours to solve

It must have gone into sleep mode, Close your laptop screen and open it again, if it doesn't work get professional help

it sounds possibly that it is going into hibernation. a single press of the power button should bring it back alive.
also feel the bottom of the laptop.... if it is getting close to meltdown you need to clean the dust and dirt from the heatsinks. the fan area may appear to be clear but all the junk gets blown against copper heat sinks so you need to remove the covers to get at it.

In Windows XP you can disable hibernation by doing the following:
1. Open Power Options in Control Panel
2. Select the Hibernate tab
3. Clear the checkbox for enabling hibernation
This doesn't work in Vista however because the GUI for Power Options has changed and doesn't offer the ability to disable hibernation. But you can disable hiberation in Vista from the command line if you use admin privileges. Here's how:
1. Press the WINDOWS key and type cmd into the Start Search box but *don't* press ENTER
2. Right-click on cmd in the Programs list and select Run As Administrator
3. Click Continue when the UAC prompt appears
4. Type powercfg -h off and press ENTER

IF this does not help write back.
