Keyboard arrows jump - Intel Dot Station (INTC300AIO) PC Desktop

then use a different method to scroll up and down like using the up and down arrows on the right column of the screen. Work arounds are my solutions for these kinds of unexplainable problems.

Keep the palms of your hands away from your touchpad.
Just being "close" to the touchpad is enough to move the mouse-pointer.

Probably faulty mouse. Try different mouse pad with no pattern on it.

what type of mouse is it? If it's a wireless optical mouse replace the batteries or throw it away, i prefer the latter

You have to set that up iin the control panel, under mouse settings.

you laptop is going through a keyboard failure.

examine the keyboard for dirt caught under the keys, this maybe diffucult to spot. this is not going to be easy at first, as the problem may lie further and at a more difficult angle, check also for damage to the keyboard and try to find a mechanical solution before suspecting the drivers here, as this looks like it may just be something caught under the keys, or the keys being dragged down together rather than a major electronic foulup.if you find nothing, then suspect drivers. after that, try checking for programming errors.

Hi Grumpy Gran
Great name by the way. Are they listed top to bottom ` a two headed arrow, caps lock, an up arrow and ctrl?
These are not particular active keys. If you have used a typewriter the two headed arrow is the tab key, use it to jump a given number of spaces to the right.
The caps lock will set your keyboard in capitals mode. The uparrow is the shift key which temporarily puts it into capitals or vice-versa. The ctrl key is a special key which is not used in normal typing. You may not need it in normal use.
Good luck with your surfing.
ps its not a good idea to unplug your keyboard whilst the computer is still on. You should connect it when the computer is off so that it is detected when the computer starts.

i would suggest buying a new keyboard

or take the key out and check theres nothing lodged in or under the key

allso

try sticky keys turn them off
