If you think you might be having troubles with overheating on your XO-1.5, the heat spreader is suspect. After removal (to change the SD, check out the motherboard, etc) and sometimes even before then, the heat spreader doesn't make good contact with the VX855 and the CPU.
I suggest bending the feet of the heat spreader slightly, as shown in the attached diagram, to apply more force on the processor/cpu. This is being worked on in C build prototypes. Cheers, wad On Nov 3, 2009, at 7:56 AM, Emiliano Pastorino wrote:
Mitch,Does q3a15 automatically throttle the processor in case of overheating?If so, is there a way to check if it is working? cat /proc/cpuinfo maybe?Thanks!

My trac tickets are at http://dev.laptop.org/report/41 . If you click on the "Action Needed" column, the "test in release" tickets will collate together. Those tickets are ostensibly fixed in q3a15. It would be good to verify those, especially if you have already participated in the ticket. Don't limit yourself to testing just those fixes, though. I need toknow about any regressions or anything else that doesn't work right. Weare getting close to the end game for XO-1.5 shipment, so now is the time to find problems. _______________________________________________ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
