Hi to all. Im having problems with my haipad mid701 with android 2.1. Im not sure if its normal or my unit has a defect. When i have low ram memory (about <20mb), my screen suddenly turns off. then, i will not be able to turn the power on for awhile even if i toggle the power switch twice. i understand that it may turn itself off when low memory but i dont know if its normal that it does not power on for awhile is it normal that it would not turn on for about 30 mins to 4 hours even if i toggle the side button power switch?
