I'm having similar issues as many others here.
My tablet would randomly reboot/freeze after I received the ICS Update. I would have to press/hold the power button to restart the device. Then I installed another firmware update a couple of days ago and now my TF will not start at all.
When rebooting, the screen would briefly flash a red depleted battery, then turn off automatically. At first I thought that I was not properly charging the device but I notice that the battery level always stayed the same (about 1/4 full) and never decreased. Even when plugged in to my charger, the battery status never changed.
At this point, I don't know what to do. I would appreciate any assistance or advice anyone could provide.
Thanks in advance.
