I'm having some problems with my n900. After a quick search I found some related threads, but can't find any clear solution. Not big problems, but I want to hear more from you guys.

1. It seems like my device is not able to boot/reboot if it's plugged in (with both wall charger/ usb cable). It rarely did, but in most cases I had to remove the cable and tried again. (common problem?)

2. Recently I've been messing around with a lot of things (cpu/voltage config, dsp, repartioning, rd mode,..) and have a lot of hangups/reboots. It think since then I can't reboot the phone with the reboot button in the powerkey entry. It instead shutdowns. (or is it because of backupmenu?)

3. With the wall charger, if the cpu load is high, it turns to "not charging" after a while. (though it charges fine in idle or through usb cable)

Anybody experienced the same things?
