SOURCE: how can disable touchpad of my COMPAQ Presario

On most Compaq's of the CQ42 model type, there should be a little light on the top right hand corner of the touchpad, not much bigger than a pinhead. When the touchpad is active the light is out so you shouldn't see the lamp. Quickly double tap the area on the lamp and it should light up. This is an indication that the touchpad is now not active.

SOURCE: how to adjust brightness of

You can do this with function keys for that model. The letters may be different, if they are, refer to the pics of the keys; they are always the same.
From the Windows desktop, hold the Fn key and press the f7 key c00776226.jpg to increase or the f8 key c00776225.jpg to decrease the brightness of the display.

Compaq presario cq62 won't start but the caps lock led blinks continuously and the wifi led remains on continuously, tried new cpu, worked for a while and started same problem again.


those are blink codes, learn to count them.
if you pulled the CPU i bet you that you used the wrong heat sink compound.
The CPU shuts off all by itself if too hot. your job is to get the fan working and the heat sink working and that thermal compound right.

On My Dv5-1125nr both the caps lock and num lock keeps blinking when i turn it on. It's wont boot at all. What kind of hardware problem is this?


First remove the battery and power cord for about a minute. Then plug back in and see if that helps. Otherwise please read the following:

LEDs near Caps Lock and Number Lock keys blink when starting notebook The LED lights near the Caps Lock and Num Lock keys will blink if an error is detected during the start up process. The LEDs will blink a number of times in a sequence and then stop. The number of blinks in the sequence indicates what component caused an error when it was being tested during start up. If the LEDs stop blinking and the computer does not start, you can press the power button again to repeat the tests. Count the number of blinks, and use the chart to identify the error condition. Knowing the number of blinks is helpful when you contact an HP support agent for technical help.

I have compaq presario cq45. When I start laptop First start fan for 5 Second then blink caps lock and num lock LED .and display not visible.I chack RAM that is proper ..


If the fan stops after 5 seconds and you can't get a display your motherboard, GPU, or CPU are shot. Remove the ram, and power it on if you hear no system beeps your, GPU, or motherboard are shot. Probably cheaper to replace laptop then repair, just remove your HDD, so you or someone else can retrieve your information for you.

HP DV6110us: 4 beeps, no boot


besides the beeps which indicate a motherboard timing issue. There should be LED blinking codes given on the front LEDs. I will include the blink codes below, but lets try to at least get the system up and running. First, I would like you to remove the RAM sticks from the laptop and just reseat one stick back in the machine. Try to boot with that one stick, if it does not, try the other alone. There have been issues when reseating the ram or re-installing it have temp. fixed the issue. If it does reboot, go to the HP support site, put in your model number of your laptop and download and install an updated BIOS. Below are the blink codes that may narrow down the problem.....
