Question about Computers & Internet

I just used my Compaq laptop computer (Presario Cq40 108TU) this morning for 2 hours. This afternoon when I was about to use it, it turned on then while starting up it suddenly turned off. I tried again to turn it on, started up but does not boot or reach Windows as is turn off again. The unit becomes very hot only after 10 minutes.

Overheated the CPU and/or GPU.
If it's the CPU, then buy thermal paste and use it. If that doesn't work, buy a new processor.
If it's the GPU, you will need to buy a new motherboard.

When the CPU overheats then it will shutdown (i.e. thermal overload) and won't boot up again until it has cooled down.If this is the problem is not fixed then the CPU will eventually fail.
A faulty fan causes this problem or the fan and heat sink assembly are cloggedwith dust.
Check the CPU fan to see if it spins freely, if not replace the fan. If the fan and heat sink is clogged withdust the remove the dust and make sure the vents are clear and dust free. Use acan of compressed air to do this.

I want to turn off the touchpad


HP and Compaq Presario laptop computers are made by the same company, so the hardware on certain models of each brand might be nearly identical. Many newer laptops, for example, use identical technology to control the touchpad, which in turn controls your mouse cursor. If you want to disable this touchpad use the software already installed on your PC.

Click "Start." Click "Control Panel." Click "Mouse." Click the "Device Settings" tab. Click on the listing for the HP touchpad to highlight it. Click the "Disable" button to disable the HP touchpad on your Compaq Presario laptop computer.

My HP Compaq Presario CQ50-130US PC Notebook won't turn on. It just flashes on the front where the lightning bolt symbol is. It was running fine an hour ago.


Two probable problems the screen or the motherboard, if you have some technical skills you can open the laptop and figure out where the problem is using a multimeter. If you are not very good with computers the best thing you can do is to take it to the service center.

My computer was fine this morning and this afternoon it will no longer turn on. The power light(white) is on, on the side but that is the only thing when plugged it. Nothing else will respond.


Hi,

Are you able to feel the heat coming up from the system after its turned on?

If yes, there may be problem with the display.
If not, the might be the problem or the underlying hardware would have been faulted.

Please get assistance from the Compaq team on this.

Good afternoon i have a compaq presario CQ61. the problem is when i turn it on the wireless network takes to much time to get ready. before i mean one year it was working good. tanx shah from Italy


I would suggest going to the HP site and see if there are any updated network drivers available. Also, has anything changed regarding the wireless router or access point? Are there other people using the access point? Has the router been moved so that there is something interfering with the signal?
These are a couple of things to check.

Compaq notebook won't boot up


Hi

When you boot the computer back up go into Safe Mode and check to see if you can roll the computer back to the point before you installed the software.

If so this should work. If it works then run a virus scan, a defrag of the hard drive and cleans the temp files.

OR

You can do a diagnostic startup and uninstall Onecare. So once that it is uninstall ed it should be smooth sailing.

Here is a link for some startup / diagnostic software you could try after booting.

I hope this helps
