You're not really turning it off.
You're putting it into standby mode.
Press and hold the power botton down until the screen goes blank.
Once it has shut down completely, press the power button as usual and it should start up.

Hello.

The most common reason is the power jack.

If you wiggle the cable where it connects to the laptop and the power goes on and off, the power jack (inside the laptop) needs repair or replacement.

If no change, remove the battery and try to power on with the A/C. If it works, your battery needs to be replaced. if it doesn't work, your power adapter probably needs to be replaced.

Hope this helps.

The Inverter is what goes out 90 percent of the time.

An LCD screen cannot produce enough light by itself. It needs an additional light source.
A Backlight is used to provide the additional light source.

A Backlight is a CCFL. Cold Cathode Fluorescent Lamp.
Similar to Fluorescent bulbs, (lamps), use in homes, and businesses, but on a Much smaller scale.

An Inverter is used to provide power for the LCD screen, and the Backlight.

A laptop's power source cannot provide enough power for an LCD screen.
The Inverter does.
A laptop's power source provides too much power for a Backlight.
The Inverter reduces the power.

An Inverter slowly goes bad as a general rule.
A Backlight goes out all at once.

An Inverter is a small circuit board located in the Display Assembly.

The Display Assembly generally consists of the top cover of the laptop, the LCD screen, (assembly), the Backlight, Metal frame going around the LCD screen assembly, the Inverter, Wireless Antenna, Bezel, and various fastening screws.
(The LCD screen is an assembly. It consists of layers, held together by the above mentioned metal frame)

The Bezel is the thin plastic frame that surrounds the LCD screen, in the front.
Once the Bezel is removed, you will have access to the Inverter.

As I am sure you are aware, HP bought out Compaq.

This is a PDF file. After you click on the above file name you won't see anything happening right away.

BEFORE you start:

1) Work on a table
2) Remove ALL power to the laptop. Remove the AC adapter (Charger) and Battery

3) It would be advisable to buy, and wear an ESD wrist strap. (Electro Static Discharge)
Connect the alligator clip to a good ground source.
(I connect to the metal frame of an empty desktop computer case, for example. You may have an object that is similar)

The cost of an ESD wrist strap averages around $3 to $6. An economical $3 ESD wrist strap will do just fine for this one-time procedure.
[ Your body carries Static electricity. Static will fry out (Short Circuit) the hardware components inside a computer. An ESD wrist strap connected to a good ground will keep your computer safe ]

4) Use a multi-compartment container for the various screws you will remove. label the individual compartments for the area the screws came out of. Some of the screws look VERY similar to other screws. You Don't want to mix them up.
[ You can use a clean egg carton in a pinch. Label each egg holder ]

5) After all power is removed you have to remove in order;

A) The WLAN Module. Page 49
B) The Keyboard. Page 52
C) The keyboard Cover. Page 54
D) Then the Display Assembly

Hi there!

To further check your laptop hardware, you need to bring it to a service center.

You need to integrate the SATA drivers for your computer in the XP installation CD using the nLite program.

Follow this guide:
http://news.softpedia.com/news/Install-Windows-XP-On-SATA-Without-a-Floppy-F6-47807.shtml

Only if you have BIOS password set. In the past, BIOS passwords can be reset by removing batteries and shorting pins. But these days, the NVRAM chips that holds the passwords needs to be physically desoldered and replaced, which makes it very difficult and costly.

Windows passwords can be cracked easily. Hard drive passwords are also near impossible to crack and protects your data, but hard drive can be replaced easily making the laptop usable.

So if didn't have BIOS password set, then you're pretty much out of luck.

Try some here -->link,

thumbs back!

Hi.
Based on the information you have provided, the issue might be due to the Windows Temp files or due to any Virus.
First, we can try deleting the Windows Temp files.
We can do this be performing the Disk cleanup.
I have mentioned the link which has the detailed steps to perform the Disk cleanup.
http://support.microsoft.com/kb/310312
Please click on the above link to view the detailed steps.
Performing the Disk cleanup should resolve the issue.
If the issue still persists even after performing the Disk cleanup, then the issue might might also be due to a Virus.
However, you may try performing a complete System Scan by using the Anti-virus Application installed in the Computer.
Please perform all the steps mentioned above.
This should resolve the issue.
Hope this helps.
Please feel free to contact for further information and assistance,

Please follow the diagnosis outlined in this article to check whether the backlight lamp or the inverter board are the root cause of the problem or not:
http://www.fixya.com/support/r6430776-troubleshooting_laptop_power_failures

If you connect the external monitor & nothing is displayed on it, then this means that both the backlight lamp & the inverter board are fine. The main indicators in these cases are the sound, and the hard drive LED on the laptop case. If the laptop sounds just like it always does for a minute or two after being turned on, it means it's going ahead and booting the operating system, but the video processor or part of the motherboard circuit for video output has failed. If the laptop just sits there and beeps when you turn it on, or if you hear the fan but not the hard drive chuckling with its active LED flashing away, it means the laptop isn't getting as far as trying to boot the operating system. While this could be due to any number of hardware problems, the most common and easiest to
troubleshoot or repair is RAM failure. If your laptop has two RAM modules installed, try booting with just one and then the other in the primary slot. If your laptop only has one RAM module, you might consider buying one online from a site with a good memory selector, like Crucial.com.

i would expect to see the compaq logo come up, and you should be able to "post" (ie bring up the bios or a diagnostic screen) even if there is no functioning hard drive.
at least I would expect it to pop up with something like operating system not found,
you might be better off replacing this one (sorry)

i had this problem on a certain brand of laptop,i finally refered to the owners manual to find FN-F5 toggled from the screen to external monitor depending on 1 click or 2 etc and that Fn-F1 put the screen into sleep mode the same way---im not suggesting your machine uses the same sequence keys but it might be worth a try finding out if you have accidently toggled your keys.
you could also be missing your OS or your bios boot sequence is incorrectly set--Press F2 whilst booting to get into boot sequence option of bios)-there navigate with tab or arrow keys--save and exit or reset settings to default and exit--dont change any thing in bios settings until you are familiar with how to navigate and select changes OK!

If you touch the laptop while it is running & you find it too hot, make sure that the fan is running properly & that the air ways are not blocked.
You can blow compressed air into the cooling vents of the fan. If you notice clouds of dust coming out, then it might be a good idea to disassemble the laptop, clean the fan & air ways, & reassemble it back. If the fan has failed & is no longer running, it might need to be replaced.

If none of this solves the problem, or is not the case, then you might have a bad motherboard.

Look at the screen at a shallow angle and look for any 'ghosts;' images that you might expect to see during boot or after.
If you can discern anything, then it could be a failed back-light (fluorescent) or the inverter for it which is customarily on a single small board that is obviously connected to the display/cover half. This is potentially user replaceable with care and a few small tools.
