Wasn't sure if I should of posted this in internal or external hardware.

My laptop touchpad occasionally goes mad and is either totally unresponsive, but more often it jumps about when you move the cursor. This does not happen all the time, and usually if you turn the touchpad off for a while and back on it will be fine for a while. I have tried a USB mouse, and that seems to work fine - although I just plugged in a USB mouse there and it said USB device not recognised. I tried it in other USB ports and it said the same error - not sure if this has something to do with it also. it is a synaptics touchpad, and I have restored to default settings, rolled back the driver and also took apart my laptop to check the connections were fine internally - but the problem still occurs.

If anyone know what the problem might be?

Thanks

Hi

I'm still having the problems - but I've worked out why.

It has something to do with electricity.

It is only when the laptop is plugged in that I have this problem with the mouse, otherwise it works perfectly.
I also find that if it is plugged in and if I have a tiny bit of water on my finger then I can control it more easily.

I'm guessing the problem is caused by static electricity - Now, A solution... Is there one?

Thanks! :thumbsup:

Is this the original power pack or a generic replacement?

It's my third replacement, Not an Original.

I bought this one because it had a right angled plug, and my other 2 had broke because the wire got bent while the wire was dangling down.

So this is my problem? I think manufactuers should look at making the originals with a right angled plug, It's a real design fault In my opinion,

When you replace a power pack you have to match the rating exactly, especially voltage. Milliamp, you can fudge a little and over compensate somewhat.
I agree about the right angle plug. They do make right angle adapters for a couple of bucks

It's a Universal charger, so there is a voltage switch on the side, and it is set to the voltage of the original - 19V
I guess I'll have to buy an original then If I want the problems to stop?

When you read the label on the unit, it will list the power required for both input and output

1000 milliamps equals one amp
