Re: [BULK] XO 1.5 blackscreen
Hi, I have a XO 1.5 that no longer boot, and display doesn't turn on at all with no booting sound. the last time I used it, I shut it by pressing the shutdown button for around 5 sec I don't know if it is a safe way to do or if it is related to this problem. A related issue, I have a 1.0 that now intermittently does not boot. It may be vibration sensitive. It hangs with I think the mic light on, black screen and no sound (of course it is booting OK now and I cannot confirm). Repeated attempts and it will boot. When it gets past this point its then OK but it might have crashed when bumped. I have a theory that its not getting enough volts during the initial power on surge due to a bad connection but that might be rubbish. The nand developed heaps of bad blocks about the same time. Any suggestions gratefully received Tony ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
