An HP Mini 200 netbook is displaying problems - intermittently, none of the keys work except the vowels, which are displayed with accents. This behaviour continues when using the on-screen keyboard or an external USB keyboard. Conclusion - the Alt-Gr key is sticking down. Returning to HP under warranty did not get the repair done, as they claimed it had been subjected to liquid spillage (the owner insists it hadn't). The "liquid intrusion sensor" is alleged to be a white paper label inside the case.
A quote to replace the keyboard amounted to £70 - but simply removing the useless Alt-Gr key fixed the problem.
