# Qool QL

Some of you who have never encountered heating problems with your QL before, might discover that about August 15, or the hottest day of the year, that your QL will suddenly blank out. Actually, it is not quite so “suddenly”. There are usually small warning signals like a ripple on the screen or the colors may start to “swim”. Unless you don’t mind losing your data, once you observe these symptoms, it is best to quickly save your data, and turn the QL off for an hour or two.
