Now, this phenomenon is not new to me, I knew my laptop has this under Windows as well. I have been trying to minimize this problem to no avail. It just happens that every 20 characters or so, I miss out on one or two,. Very annoying when typing a password, and especially when SETTING passwords. I have read it had to do with the embedded controller and lost interrupts when the battery status is polled. I also read somewhere the polling interval is rediculously high (every 1 second) when windows polls this with a less interval which can be the reason the missing keys are less frequent under windows. Is there a way to lower the polling interval of the battery, or even better, fix this problem? My system info: Suse 9.3 Kernel 2.6.11 Acter travelmate 4001WMLi Panasonic battery Any help is very much appreciated as I really would like to use Linux, but the missing keys make it hard to enjoy using it :-( Regards, - Jorgen ------------------------------------------------------- SF.Net email is sponsored by: Discover Easy Linux Migration Strategies from IBM.
