Any external USB mouse can be connected to the system. As well as USB keyboard. Or specifically if you go through HP, the mouse part number is: NR152AA, and keyboard is GM321AA. As far as non-HP products you will need to check on compatibility on each. Hope this helps you in this question.

My laptop has so many errors that it want spell right, you can be writing & the curser will jump back to the middle of another word that you have typed

This may be problem with the touchpad (mouse function) or with the built-in k/b.
I think that it is possible to adjust the sensitivity of the touchpad; try to reduce it.
You might try to use an external mouse and/or k/b to see if this makes any difference. There are many that connect to your computer through USB ports, either one transceiver for wireless keyboard and mouse, or separate USB k/b and mouse needing a USB port each. You may need to install drivers for some of these either from a CD or the internet. In the former case there should be instructions, in the latter, your computer might search the internet and download and install automatically.
It might even be corrupted driver problem; if this is a possibility you might try downloading new k/b and/or touchpad drivers from the HP website - search for dv7-1245dx in the search box.
If your computer is out-of-warranty for support (if it's in warranty go direct to HP support !), you might try posting this question in HP community support forum, accessible through the HP website. Also, look for this problem (in similar models too) to if anyone has encountered and solved it previously.

You will need to go to and download your VISTA drivers for video.
And you should check your device manager for flags, as you may need to get other drivers as well.

Check the touchpad on/off button at the top of the mouse touchpad on the laptop, it's small and can easily get turned off by accident and you will think your mouse has quit working. There is usually an indicator light next to it. I'm not sure but on your laptop I believe it may be a blue light when the button is on and turns orange when switched off.
