Over the last couple of days I’d noticed that my Treo 750 kept turning itself on. Switch it off, it comes back straight away. Idle timeout, it turns right back on. It was starting to drive me nuts.

Stumbled over the solution…

In preparation for a couple of days of travelling, I turned down the brightness on the display of my Treo 750 to conserve battery life while reading ebooks on the plane. It turns out that there is a known bug whereby if you turn the brightness down to past 40% it will constantly turn on. Nice way to save power!

The solution is simple – turn the brightness back up.
