Removing Lenovo Ideapad S10e lid switch
The Lenovo Ideapad S10e is a compact and highly efficient netbook-computer. For the Salvius robot this computer has been installed with a copy of Ubuntu Server Edition 11.10 and acts as a file server and communication hub between the robot and other devices.
The Lenovo has a single flaw at this point that makes it less useful for robotics. As with most laptops the lid switch puts the computer into hibernation when the lid is closed. When using the laptop for robotics it would be better if the lid could be closed and the computer would remain on. The Windows operating System has options to control what happens when the computer lid closes but Ubuntu Server does not. The best thing to do in this case is to physically remove the lid switch which for the Lenovo S10e is surprisingly easy.
The Lenovo S10e's lid switch is composed of a small magnet located in the right hinge of the screen and a reed switch near the motherboard. To prevent the computer from going into sleep mode when the lid is closed all we have to do is remove the magnet.
Begin by unplugging the computer's power cord and then remove the battery pack:
On the sides of the screen there are four rubber tabs stuck over screws. Two of the tabs are round and two are half-round. Remove the rubber tabs with a small flat-blade screw driver. Underneath each tab is a small Philips screw which you must also remove.
Next Pull off the plastic LCD bezel; it should come off somewhat easily if a thin flat blade screw driver is slid behind it while being careful not to damage the screen.
Once removed the lock cap should be able to be popped off the side. The cap is a half-round black piece of plastic with a silver plastic disk on one end. Inside there is a small rectangular magnet.
Use a pair of needle nose pliers to break the magnet away from the cap and then remove any remaining shards of plastic.
Restore the parts you removed in the same order as you took them off. Make sure to discard the magnet or put it somewhere where you can find it if you decide you want to put it back in again.
(laptop hinge with the lock cover removed.)
Now the lid of the computer can be closed while the computer remains on.
