guys, from past a week my phone has been turning off whenever i close the keypad or when i hit the n900 from outside. ( im not hitting it with a rod or a big stone, just a tap).

someone told that due to water content in n900, this problem. actually ive been cleansing the usb port of both charger and n900 with water because it keeps getting covered with dust. so there will not enough voltage flow to charge the n900. i have been doing that for a couple of months but there wasnt any problem. now, all of a sudden i often see my n900 switched off!
