Dell Studio 1735 Touchpad problems

hello guys, i have had this refurblished laptop for a few months now and recently it has developed a problem. When the touchpad plays up it will not respond and occasionaly will jump all over the place making it impossible to use. It has been doing this for a few weeks usually about once a day which i thought was completley random, although about 5 minutes ago I discovered unplugging the charger solves the problem. Can anyone suggest any fix for this? I have tried reinstalling the touchpad driver with no success.

Many Thanks,
Graham.

 

If you're comfortable with opening the laptop up and removing the keyboard and palmrest, you might want to make sure the cable connecting the touchpad and the motherboard is secure and not damaged.

 

thanks for the reply, I woud be comfortable with that but I have been testing it with the power cable, it does only mess up when the power cable is plugged in and as soon as it is removed it works fine again. I have been doing this for a while it is definately the trigger of it.

 

I'm buying a similar laptop tonight, ah this is not good. hopefully it does not have this same issue

 

also discovered that if the power cable is plugged in and a hdtv is plugged in with the laptop screen dissabled the mouse is cured, and if hdtv is dissconnected it will return to spazzing, this is really wierd!

 

I hope this is the same problem u had...
Try updating the bios. It may seemd weird but after I did this both my touchpad and keyboard worked fine. Before this, if I installed the driver for touchpad, it didn't work at all; when I uninstalled the driver the touchpad worked like an ... but worked. Only aflter the bios update (and than installed touchpad driver) it worked fine. On the keyboard I had to push very hard fro it to write what I type. This problem also fixed by the bios update
Hope this helps because it sure cost me some time to solve it
