I downloaded and installed the rc2 spin and same issue exists. As i think think its too late too fix this before the f13 official released i suppose the fix might be in updates.

Comment 3 James 2010-06-13 08:33:59 UTC
I keep tracking update every day but till now at least, it is still unsolved. luckly i did not abandon win7 on my laptop and now i can use dual boot back to win7. hope it can be solve soon.

Comment 4 Daniel Tofahrn 2011-05-01 18:31:05 UTC
I have a Lenovo IdeaPad Z360 with Fedora 14. I've installed F15 beta and the problem with brightness always stays up. I decided to give Win7 but have to return to MS since it is impossible to work with brightness always 100%.

Comment 5 Bug Zapper 2011-06-02 14:21:02 UTC
This message is a reminder that Fedora 13 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 13.  It is Fedora's policy to close all
bug reports from releases that are no longer maintained.  At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '13'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 13's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 13 is end of life.  If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here: 
http://fedoraproject.org/wiki/BugZappers/HouseKeeping

Comment 6 Bug Zapper 2011-06-27 16:10:55 UTC
Fedora 13 changed to end-of-life (EOL) status on 2011-06-25. Fedora 13 is 
no longer maintained, which means that it will not receive any further 
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of 
Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.
