HP Pavilion DV5 touchpad not working

I just got this laptop a week ago and have already been on tech support several times for this same issue. They don't seem to be able to find a permanent fix. I remove the battery, clear the capacitors, reinstall the BIOS and mouse drivers and that will get the touchpad working again for a little while, but it very quickly just stops working again. And by stops working, I mean nothing works. No buttons, no moving the mouse, no nothing. There is a on/off button for the touchpad, but that is in the on setting and doesn't seem to work when the touchpad's not working either. I've also read about a Function+F7 issue with Synaptec pads, but that doesn't seem to make a difference either. It's running Vista Home Premium 64. Any ideas?

I have the same issue with mine, and i just got it three days ago. I cannot tell you how to fix it entirely since i believe it's a design flaw, but i can help you keep your touchpad working for longer.

If you have noticed, these laptops get quite hot. Also the cooling vents are at the bottom, so if you keep the laptop on a soft surface such as your bed, the vents are essentially blocked. When the touchpad gets too hot, it stops working.

So, how to keep it cool you may ask? For one, do not keep it on the bed while it is turned on. Secondly, ALWAYS keep the battery out when you are not using it, as it gets hot as well. Also, keeping the battery charged at 100% for extended periods of time wears it much faster than if you actually use it. Search for the web for "Li-Ion care", there is plenty of info. If you need to have some battery power available at all times, use the laptop on battery power until it reaches 60%, then plug the adapter back in, and unplug it again once it's fully charged and so on. This is still much better than keeping it at 100% all the time.

Btw, the reason why it momentarily starts working again when you reset the BIOS it's because it cools down a little when you do that, the system load while in the BIOS is almost zero.

    Update: I have repaired my touchpad. It was the heat that made it stopped working, but the actual fault was caused by something else:

    The ribbon cable connecting the touchpad to the motherboard was bent too sharply at the factory and it broke. Since it was long enough, I used an X-Acto knife to cut the broken part off, and saved the blue plastic tab. I placed a thick plastic sheet over the touchpad area so i don't scratch it, laid the ribbon cable on it and with 180 grit sandpaper slowly grinded at the plastic to get the wires exposed. When i got enough length of wire i plugged the cable back into the connector and used the original plastic tab to hold it in place. It worked. I then put a drop of glue on the connector and put the laptop back together.

    Only attempt this if you're brave enough, have very good eyesight and lots of patience.

For most people viewing this problem first check the on/off button before getting this involved. There's a little button in the top right that turns the pad on and off. Its there so you can turn it off and use a USB mouse instead. You can leave it on and have both working simultaneously I suppose.

On laptops, sometimes your TouchPad is disabled for no apparent reason. To reactivate it, first try restarting your PC. If there's no good change just try:

We need the software driver and your mouse are installed

This trick works in Windows XP and Windows Vista.
  • Go to Control Panel> Mouse> Settings tab of the device
  • Click (or to disable)

Notes:
  • On some models, there is a keyboard shortcut to activate or deactivate the touchpad. For example, a ACER, just do Fn + F7.
  • You can click Reset device if neither of those solutions will work.
  • The official website provides synaptics drivers and software needed to run your TouchPad.
  • On the latest laptops, there is a special button to Enable/Disable the Touchpad.
  • HOPE THIS HELPS

I am using a HP Pavilion dv4-1242tx. While using my touch-pad,I have to press 3 times to click on an item.. Why is this so? This is very very irritating..


The issue could be with the corrupted touchpad drivers.
I recommend you to uninstall and reinstall touchpad drivers.
Press Windows key and R key simultaenously.
Type devmgmt.msc in Run window and click on OK.
Expand Mice and other pointed devices.
Right click on your Touchpad Synaptics or Alps and select Uninstall.
Also Update your driver after reinstalling them.

Daughter has similiar problem with keyboard on inspiron 1545


Dont just fall for their promises. If your external keyboard works fine, it is surely a manufacturing fault. Insist on a replacement or a service. Tell them your external keyboard works fine and make sure you sound like a techie. People at those companies think we are dummies. Good luck

Can't "tap" on my Dell touchpad


I had the same problem after purchasing an HP laptop with a Synaptics TouchPad. After using a wireless mouse for awhile, the TouchPad stopped working. The TouchPad light was white, indicating it was enabled. No TouchPad devices was listed anymore in the Mouse Properties in the Control Panel. I tried reloading the driver but nothing changed.

After shutting down the laptop and removing the battery (according to owner’s manual) it worked again. After turning on the laptop, make sure the TouchPad works. Then go to Control Panel, Mouse, Device Settings tab, and make sure a Synaptics TouchPad is listed in the Devices list and that the Enable button is grayed out.

Hpdv9000 laptop mouse wont work


Check if you have installed the latest drivers...
For the touchpad, you should be able to find them on the hp support site
For external mouse, there should be drivers on the manufacturers site or the driver disk that came along with it.

Is it the touchpad that doesn't work, or is it an external mouse?
