[Q] Has anyone noticed that, when running on AC with a fully charged battery
pack inside, the backlight gets noticeably brighter and dimmer at three second
intervals for about a minute every hour or so? I've got a 4/33C with the
extended life NiMH battery, and thought it might have something to do with the
battery being "topped off" when already full. The symptoms disappear when
running on AC without the battery pack, with the battery alone, or while the
battery is charging.

[A] I have the same problem and I do like you when it appears, I disconnect the
power supply or put away the battery.

[A] I experienced the problem under the MS-DOS 6.2 which came with the system.
I was watching it for a while last night; 70 pulses, each lasting about 1
second, for a period of 4 minutes, every hour--like clockwork. Business Depot
exchanged the unit today.
