Observe if the processor cooling fan is spinning that cools your processor. Or your unit need cleaning where the vents of your laptop is clogged with dust and the cooling system will be affected that made your system shutdown automatically

I have a problem with my compaq presario cq42, i am not find out my wireless option,even i was downloaded hp wireless assistance and others driver but nothing happen. Please give me some idea!!!!!


If you can download then I expect the wireless bit is working. Try re-booting with an Ethernet lead plugged in, download the latest drivers from Hp and clicking on the downloaded name will install the driver. Ensure you choose the correct driver!

I have no drivers for my compaq presario cq42.no driver is installed


Hi gem,

Which operating system are you using? What drivers are you missing when you get into "Device Manager" (assuming you're using some version of Windows?

http://h20000.www2.hp.com/bizsupport/TechSupport/ProductList.jsp?lang=en&cc=us&taskId=135&prodTypeId=321957&prodSeriesId=4121902

Above is the link to Compaq... you have to select your specific model of CQ42 (look for the sticker under your laptop), choose your operating system and download the relevant ones.

I often install drivers with the motherboard first (most likely an Intel chipset), then all the rest such as graphics card (video drivers), audio, networking, wireless, modems, card readers, etc.

Hope this helps!

I have laptop compaq cq42 but webcam can not use


HP Compaq has several different models for the CQ42 notebook. If you are haveing issues with the webcamera my first suggestion is to re-install the driver and software for it. I have included the web link to HP Compaq support page. You have two options, 1) Is to input your product name or product number. The product number is the best way to get the correct software and drivers for you notebook. If you dont know your product number there are instruction on the support page that will show you how to find your product number  2) Have the support site automaticly detect it for you.

I just bought Compaq Presario CQ42 which black in color (i don't know the model exactly). i have a problem with the touchpad. i want to lock it but i didn't find the button and i don't know how to lock or...


Underneath the Laptop is a Users Label marked Model it should give the FULL model No. - e.g. Presario CQ42-100 - HP made something like 150 different models for the Presario CQ42 !!! so you can see, I'm going to have to guess about this...
If your Touchpad has a black(?) dot in the top left corner - tap this once to turn the Touchpad off while you are typing.
Touch it again, to turn it back on.
Other Presarios' have a switch nearby to do this...
