The mouse pointer on my HP nc6320 jumps around intermittently and is very difficult to control. This problem only occurs when the laptop is fully charged and is running off the battery. If the battery is charging it's fine and also there is no problem when the laptop is running from the battery. Any ideas what could be causing this? Thanks in advance and Happy New Year 2010! Alan

run it in battery to see if fixes cursor problem
also try a different mouse see if that makes the cursor move correctly
this way you see if its the mouse or power supply
might also a touch pad problem anything that controls the cursor

Do you use an external mouse or the built in touchpad/pointing stick? If you use an external mouse try another and see if the random movement disappears.
If you are using the touchpad/pointing stick for day to day use, plug in a mouse if you have one spare, go to the control panel in whatever version of MS Windows the laptop is running and do the following:Start Button > control panel > mouse (goto the hardware tab on the window that opens) choose the 'synaptics' device > properties > driver > choose 'disable' then ok. This should disable the touchpad if the random jumping stops then it is probably a physical problem with the touchpad/pointing stick, you may want to contact HP and request a repair.

Link below is to manuals for your laptop model:

Hi, to adjust the touchpad settings for your Toshiba L505 kindly follow the Step by Step intruction guide on this link,

http://www.csd.toshiba.com/cgi-bin/tais/support/jsp/outFrm.jsp?ofId=AskIris&searchString=Mouse+pointer+jumps+around+as+you+type

You will see several search results, just click the topmost result which says "Mouse pointer jumps around as you type". You will then see a detailed guide on how to adjust touchpad settings. Hope this works for you.

Go to your control panel and double click on your mouse icon to get to your mouse properties. Go to "Pointer Options" and make sure that the "snap to" box is unchecked.

Did you replace the batteries?
Could be a bad mouse. Do you have a friend you can try their mouse? If theirs works. Time for a new one. They do go bad. I've replace many of them!

Have you tried going into the control panel - mouse - pointer options - motion speed (slower) and experiment with pointer precision check box? Try it, see what that gets ya.

Go to the following link:

...choose the appropriate operating system you have, download the driver files for the "Chipset" and run the file afterwards. Reboot and test the USB mouse. The chipset drivers are for updating the software for your motherboard, which includes the USB controller.
