I hope someone can help me. The problem I'm having is with my touchpad on a Dell Inspiron 1545.
When i first turn on the laptop the touch pad works fine for about 4-5 mins max.
Then it will start behaving very erratic , as follows
1.Pointer will slow down when trying to move it.
2. Pointer will sometimes not respond at all.
3.Pointer will start jumping around after placed somewhere e.g When finally got pointer into position to click on an item it move off on its own.
4. Pointer starts shaking.
If i plug a mouse into the usb port everything works fine using the mouse but remains the same on the touchpad
I'm running Vista home premium 32-bit with SP2.
What i have tried to fix this.
From Device manager found that touchpad driver is Alps Electric version 7.1007.115.102 installed 02/05/2010.
From device manager >update driver. It looks for updates and says latest software is installed.
From Dells website find drivers and downloads section,enter service tag number. The driver they recommend is the same version as i already have installed.
Downloaded anyway and installed .Result the same.
Ran a full scan using McAFEE, ran a full scan using Malwayre bytes, ran a full scan using Spybot Search and Destroy. Result still the same.
Used M/S Solution centre .Result still the same.
Ran a driver scan by Iolo recommended by Dell. Result all drivers up to date.
Out of curiosity ran another driver scan by Uniblue. Result nine out of date drivers including the Dell touchpad . An updated version was available version number 7.1207.101.220 Dated 08 Feb 2011.
Revisited Dell website but could not find the version as it did not tie up service tag number. Tried to download without using service tag number but with no joy.
Am i on the right track assuming it is an driver error or could it be something totally different?
Any ideas anyone.
Many thanks in advance Dominic
