if you are familiar in tearing down the laptop, here is the step by step process... Turn off the laptop, remove the cables and battery.. Then press and hold power button for 8 secs.....remove the screws at the corners of the laptop bottom. Remove the Hard drive, remove the optical drive, remove the screws at the front of the laptop.. Remove the keyboard , and then remove the cooling fan just above the processor and replace it...

Your computer your laptop will just shut itself down and get a black screen unexpectedly, which is due to: power overload in the AC adapter, overheated processor / clogged fan, overheated battery, pushing the power button, Windows telling it to, the BIOS telling it to, loose wires (especially the power cord), or intermittent short circuits. The most common problem is cooling. the battery should be removed from the laptop and allowed to cool to room temperature before attempting to use again. Notice if the fan is broken or clogged with dust.

1. Take the battery out of the laptop & try to turn on the laptop using power adapter only. If the computer turns on, then the battery is defective & needs to be replaced.
2. Make sure the power adapter is not defective. Test the output voltage of the power adapter using a voltmeter. Compare the voltmeter reading to the nominal value written on the adapter or the laptop.
3. Make sure the DC jack is not loose or broken. A loose DC jack will need to be re-soldered. A broken one will need to be replaced.
4. If you have another processor which is compatible with your laptop's model, try swapping processors & test to see if the laptop will work.
5. The power button could be bad.
6. The motherboard could be defective & needs to be replaced.

We can troubleshoot the Overheat issue but first we need to turn it on. Perform following steps and check if you can see the diplay on screen.

1. Disconnect the AC Adapter.
2. Remove the Battery.
3. Hold the Power button down for 30 seconds to 1 minute.
4. Reconnect the AC adapter and do NOT connect the battery now.
5. Turn on the Notebook power.

If the Notebook power up and shows you display, then proceed with further steps (or you can connect a desktop monitor to check if its displaying. Press Fn+F4 to toggle the display on external monitor)

The notebook may overheat and make noise or stop working due to the following conditions:
1. Due to incorrect power supply from the AC adapter.
2. If the Fans/Heat Sink are not working properly.
3. If the power management and BIOS settings are messed up in the Notebook.
4. Finally due to other components on the system board.

To resolve this problem with overheating, perform following steps.

I check your Laptop and see that your Laptop product number is "GA534UA#ABA" with Windows® Vista Home Premium pre-installed, if you are using the same, process with following steps.

Step 1: Reset the BIOS to factory defaults:
1. Click Start, Turn Off Computer, Restart.
2. When the HP logo appears, press F10 to enter BIOS Setup.
3. Press F9 when you are in BIOS Utility to load the BIOS to default. Click YES. Then press F10 to Save & Exit.

Step 2:Re-install Power Management in Vista
1. Press Windows key + R
2. Type devmgmt.msc and press enter.
3. Click the plus (+) sign next to System Devices.
4. Right-click the ACPI Fixed Features button and select Uninstall.
5. Restart the system.
On restarting the system, Windows will automatically detect and install Power Management on the computer.

Step 3: Installing an update for BIOS:
Caution: Install this BIOS only if you are using pre-installed operating system with above mentioned Product number.

In case there is no display, remove and reseat the Hard Disk and RAM and check for the issue. If display comes up after removing and reseating the RAM and HDD, then you need to follow the above steps again.

NOTE: If you have more than one memory module, you should test them individually to determine if one or both of them are faulty. Insert each module separately, then turn on the notebook to determine if the inserted module is working. Once you have determined which memory module is faulty, you can replace the faulty module and reseat the working module.

Hello, You have enrolled fingerprint right?? then what is the problem... as soon as it boots up press your finger on the sensor...

I will be glad to share my little knowledge in this senario.
Basically, I am personally a fan of AMD processors who is the first to manufacture 64 Bit Processors for Desktops and Notebooks.
However, if you remember, Intel started concentrating on Performance and not on Speed after AMD was able to design processors which were able to outperform Intel processors with slower speeds.
So, you need to look into Performance and not into Speed of the Processor.
Coming to the processor installed in your notebook, it is normal but I recommend you to use Windows XP than using Vista since Vista need more RAM and processing power when compared to XP.
Also, Windows Vista Home Basic is the basic version among the Vista family with very little features.
Coming to the Heating issue, this is common for all Notebooks to heat up when used for long time since the Notebook parts are palced in a very small where if any part heats up, it is passed to other parts too.
Make sure that the Cooling Fan Vents in the Notebook are not filled with Dust.
You can find these vents located at the rear of the notebook from where the hot air should be emiting from inside the Notebook.
I recommend you to use a Vaccume Cleaner or Air Blower to blow away invisible dust which might be blocking the airflow.
Also, make sure that the Notebook is placed on a flat surface like a Table so that there will be air flow from the bottom of the Notebook and the Cooling Fan will be able to **** in the required air from the bottom and dissapate the heat generated by the internal components.
Also, check for any BIOS Update is available for your Notebook related to this issue and update with the same.
You need to contact HP Chat Support and get the exact BIOS Update for your notebook since updating the BIOS with incorrect Update will make the Notebook useless.

Hope this gives some idea about your doubts.....
