UPDATE: The Toshiba forums have a rep that is working on this issue. I sent him a PM (he is asking all folks with the issue to do so). Go to post 10: Thrive not waking from Stand By - requires reboot - Toshiba Forums End update I have seen posts about this in other forums and I am having it as well. It is hit and miss if the device comes out of sleep mode and just happened again. Pressing the power button sometimes does not wake the device up and you have to hold the power down to shut off and then restart. This has happened three times so far. Besides this issue (and the stiff power button), the Thrive has been outstanding. Anybody have a fix, besides returning this fine device? I did the update that was released. Update: It is now having the issue all the time. I have tried four times now and still not coming out of sleep, forcing me to hold the power down to shut off and then restart. Mega bummer, since besides this issue, the Thrive rocks. Update 2: Now working again, but nothing I did to fix. Seems a random issue. Ironic: The the A500 will not stay asleep and the Thrive will not wake up. Both great devices besides this.
