Introduction: Keep Your Computer Awake With a Cup

Picture of Keep Your Computer Awake With a Cup

This is a really handy tip for wanting to keep your computer awake or keep grooveshark playing, using a cup. 

Laser mice only... 

I don't use this hack myself, my desk is glass and causes this effect anyway, plus the mouse wets itself if you don't use a mouse mat like the ever classy sheet of a4 paper.

Step 1: Put a Cup Upside Down...

Now balance the mouse so the sensor is hitting the corner of the cup. 

When it's right the mouse will keep the bright LED for moving on instead of stopping after a few seconds.

Step 2: Or Break a Glass?

I broke a wineglass the other day, one of the pieces suits this purpose perfectly, though any lump of transparent material will do.

Ummm that's a drinking glass, not a cup, which are usually made from porcelain or stoneware, unless it's made from Pyrex. Just sayin...

Oh btw, interesting idea. Pretty much anything reflective should work. Rest your mouse on a small piece of aluminum foil, or even crumple a piece over the entire mouse, so it can't get bumped off by accident. Cheers!

just change it in the control panel........

im no doctor but it sounds a hell of alot easier than that balancing act of yours.

Kyle, this is for large managed networks where logoff or desktop lock policies are pushed across the network by IT Administrators.

It takes no time at all either way but this works for sites like we7 and grooveshark where no system setting will.

Plus its

Grooveshark stops playing even if the system itself is not asleep?

Yeah, so if you leave the page open, do this mouse trick and itll go indefinitely, unless you have my computer, which sets itself every six hours...

Can you explain further this behavior of grooveshark...?

It stops playing and brings up a message, they work by showing ads by the player so I guess thats why they do it, if the page can be left buried then its no good to either party.

I like this solution better because I just set it on the glass desk, a picture frame would work too.

Ohhh, I see.

Well, I certainly see how a "hardware" hack like this is nice - nothing to install, and very fast and easy.

Oh and why not use something like Mouse Jiggler?

A small mirror works as well!

I don't get how this works because I just got a wireless laser mouse and the pointer arrow thing is moving randomly by itself and it's on a wooden desk with no glass chips or anything.
