Much larger temperature differences exist when running on battery in a 70 degree room and running on battery in a 90+ degree room. Ideal temperatures for any computer include both 70 and 100 degrees. Temperature is not a reason for failure. Temperature is a diagnostic to find defective semiconductors. Any computer that works fine in 70 degrees and fails in 100 degrees is defective. And will probably get worse over the months to also fail in 70 degrees.zoocrewphoto wrote: Temp may be an issue. I will get one of those cooler things and see if that helps. I do tend to run it all the time and just leave it on. Same thing when I travel, though it does have a few breaks as I move from hotel room to show hall, and back.
Put it in the warmest room possible. Does it still fail when it should switch flawlessly from AC to battery? And does it always work in a 100 degree F room? Both are diagnostics to identify (characterize) a defect.
Laptop must switch from AC to battery to AC repeatedly without any indication (other than its power Icon).
We really don't have much in the way of hot temps here in Seattle. I can tell you that the crashes happen randomly, sometimes while I am using it, and sometimes while I am asleep and it is idle. It has never happened when I unplug it and let it go to battery. So, the transfer to battery is fine.
