Description of problem:
With ACPI enabled, I can put my ThinkPad X24 laptop to sleep (S3) and
wake it back up again. However, while the laptop is asleep the
internal LCD display remains powered on. The entire display is a sort
of dark gray color which is notably brighter than the black one would
see e.g. in a text console or with an entirely black X window. This
tells me that the LCD display is still powered on in some respect.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. echo 3 >/proc/acpi/sleep
Actual Results: LCD display is a uniform dark gray, indicating that
power is still being drawn off to illuminate the display.
Expected Results: LCD display should go completely black, indicating
that no power is being drawn from the batter to power the display.
Fedora Core 2 has now reached end of life, and no further updates will be
provided by Red Hat. The Fedora legacy project will be producing further kernel
updates for security problems only.
If this bug has not been fixed in the latest Fedora Core 2 update kernel, please
try to reproduce it under Fedora Core 3, and reopen if necessary, changing the
product version accordingly.
The bug still occurs exactly as originally described using Fedora Core 3 and
An update has been released for Fedora Core 3 (kernel-2.6.12-1.1372_FC3) which
may contain a fix for your problem. Please update to this new kernel, and
report whether or not it fixes your problem.
If you have updated to Fedora Core 4 since this bug was opened, and the problem
still occurs with the latest updates for that release, please change the version
field of this bug to 'fc4'.
Since this bug was first reported, I have:
1. replaced my ThinkPad X24 with a ThinkPad X40
2. upgraded to Fedora Core 4
3. upgraded to the latest 2.6.12-1.1398_FC4 kernel
The problem does not appear in this configuration, but I cannot say for certain
which change made it go away. The change in hardware is as likely the cause as
any real software fix.
Should I resolve this bug as WORKSFORME? Let me know what you want me to do here.
Ok, I'll just close this. Thanks.
