CURSOR JUMPS TO THE LEFT

You may want to consider disabling the touchpad all together while typing for extended periods.

Click the Windows "Start" button or press the "Windows" key. The "Start" menu opens. Type "Cursor blink" in the "Search programs and file" text box. A list opens. Click "Change Cursor Blink Rate." The "Keyboard Properties" window opens. Click the "Speed" tab. A list of options appears. The "Cursor Blink Rate" section shows a "Cursor Blink Rate" slider displaying a range from "None" to "Fast." Click and drag the slider button to the "None" area in the far left portion of the "Cursor Blink Rate" scale. Click "Apply." Click "OK." The cursor stops flickering on the screen.

Open touchpad properties, touchpad settings section, enable Touchcheck, set the slider to minimum setting Click OK
TouchCheck disabled the touchpad while typing

The Cursor jumping can be resolved by going to the touchpad properties and enabling touchcheck (Palmcheck is some drivers) this will disable the touchpad while typing.

Ad far as dealing with heat, canned compressed air blowing dust out of the air intake/exhaust will normally help cooling

Hi,
I guess the 'other places of the pages' is mostly the beginning of the line? It usually happens when the key stroke is not proper while using combination keys. Or also it happens when if you dont release a key when you press the next in between your speedy typings.

It is a fault with Lenovo laptops. My cursor jumps all the time, no matter what software I am using. It is NOT the 'sensitivity' of the touchpad, for my cursor jumps even when I am not typing, even if I don't touch the laptop! I can set the cursor to a certain point on a document and then, after about 30 seconds, it will just jump to another point, even if I am in another room.

1) Better you shift some installations to other than C from atleast now
2) Its quite a bit problem if you are using laptop by accidently touching the mouse pad...
3) not necessary to have but fine to have to seperate things

maybe its keyboard problem ,some keys on ur keyboard.open a new text document and test all the keys of keyborad if any type more than 1 times when u push u have to clean under that key .

Is the touchpad active?
It is common that users accidently touches the touchpad while writing and this causes the cursor to "jump"...
Another possibility is that the "TAB" key is jammed...

I have found this is usually the small button in the middle of the keyboard (mouse button) I have tried some software to remove this problem but it did not on my laptop I ended up carefully removing the key board and disconnecting the two wires that go to the button My cursors kept moving across the screen
