    Hello

    Just wanted to share this little surprise: my 3 year-old znote 6224w recovered its display capabilities, just like that as if it never stopped to work!!

    I thought the GPU was toasted for sure a year ago, when the screen went all black without any hint of life. Back then, I did reboot a zillion times, tried the sleep trick (to delay GPU downclock), etc without success.

    After a year, I just booted the thing to try and get some old file. On boot the screen was still black, nothing out of the "normal". I got XP on it set up with a password, but I had forgotten that, and somehow the combination of keys I blind-typed made the laptop go to sleep mode. I woke it up and soft-rebooted and there I got the display back !!

    My point is, I don't know exactly what made it work again, because I could not repeat he experience (it's been shutting down and rebooting fine since then) but I suspect it's something like "boot, sleep, wake, soft-reboot". Probably combined with some long term mechanical effects on the chip materials, I can only guess.

    I had a similar experience with my current motherboard / cpu. in my deskltop computer. This time last year I was moving files from my OS HDD to my 1TB Backup HDD and I left it do its thing. It seemed slow but I thought nothing of it and went yo watch TV for an hour. When I got back to my computer the monitor was on standby and iyt wouldnt wake up. So I rebooted and I got a CMOS Error on the CMOS Error LCD I have with my Asus Maximus Formula. So I reset the Bios and still no go. So I took the CMOS battery out and plugged out the power from the mains hoping it would work , but still no go in the morning. I then tried all tricks I knew to get the machine to boot up but nothing worked.

    I went back to my backup Motherboard and CPU for six months but was fedup of the slower Dual Core CPU so I tried this motherboard again with the Q6600 that refused to work six months earlier. To my surprise I got a POST screen and its been working better than it ever did since thne.

    Electronics do funny things sometimes.
