BIOS Display Settings Change Spontaneously
Posted: Sun Jul 18, 2010 12:03 am
This problem is a glitch that I can live with if there is no solution.
I've been creating scripts for years, so I usually find work around
solutions for most problems. This time, I'm out of ideas!
I used a customized version of 98SE years ago, when I started a small
business with few other guys. We had one copy left that was loaded
onto an old (and very large) Gateway. I purchased a completely refurbed
IBM T23 ThinkPad, and gradually moved the system onto the laptop so I
could finally junk that huge Gateway desktop.
The ThinkPad works great. I updated the BIOS and Embedded Controller,
but there is one annoying problem. Under "Display" in the BIOS setup you
have three choices, LCD Only - CRT - Both. Like most laptops, these
settings allow you to use an external monitor. There is also a very good
ThinkPad Configuration Utility that gives you the same choices that are
available in the BIOS setup. If you don't want to use either one, you can
toggle the display by pressing Fn+F7. Fn is a special key unique to ThinkPads.
Without warning, the display settings change in the BIOS setup. You can
immediately restore the laptop's display by pressing Fn+F7. I have the service
manual for this ThinkPad. The first thing I checked was the CMOS battery
voltage. It tested good, but I replaced the CMOS battery anyway.
All the updates for this T23 were downloaded from the Lenovo site. The only
exception were the chipset drivers I got from Intel.
I suppose I should be happy there are no other hardware or software malfunctions,
but it sure would be nice to resolve this one problem.
I just went to the Phoenix site and clicked on their link for BiosAgentPlus. Maybe
there is a newer update for this ThinkPad's BIOS. (I assume the update I got from
Lenovo is the latest.)
If this is a buggy BIOS problem, there has got to be a work around. Some kind
of script or little applet maybe. All I really want is the laptop's display to stay
turned on. Setting Power Options > Turn Off Monitor to "never" doesn't resolve
the problem. Naturally, the BIOS settings override any Windows software.
Any suggestions would be appreciated. Thanks guys.
