11. It is difficult to duplicate problem. The main approach is to set poweroptions to go computer to sleep after x minutes. Sometimes it happens when you put machine to sleep manually. But problem arise when you take laptop back (wake-up). It seems that it have to take some time before you put machine in to sleep and then wake it up, not so short as 30 seconds. Not always the problem arise randomly. If the problem occures all other hotkeys are working propperly, only brightness don't work. I have even tried to open Power Management and try to set brightness manually (with cursor) but it doen't work, even stichning power plans, brightness remains the same level. I seems to be purely software/driver problem as wen I activate screensave Fn+Home (brigntness up) interrupts it, so keys are ok, signal is send, only no action on windows side. I have tried to hibernate and restore, during Windows start up I am able to change brightness, but when Windows is loaded brightness level is again reset to saved value and is unchangable :) The way to recover from error: 1. restart, easiest one, 2. you can put to sleep your laptop manually (not sure) or give it to go to sleep after x minutes (sure) and after wake up SOMETIMES it start working again (4 of 10 times), most likely not from the first time.

I have installed original x64 Windows 7 Professional and installed all drivers from Lenovo Update and Drivers utility only, nothing special was done. Problem was noticed before SP1 was installed. Today 12.03.2011 I have all reacent drivers installed via Lenovo Update and Drivers utility.

I have made Everest report in MHTL (IE format) and put it here http://www.rasayana.lv/t400.zip

It should contain all the detailed information about my notebook and installed software.

The Brightness control doesn't work after hibernation

The problem was started to be discussed in this thread

As pleased by an admin i open a new thread to discuss the problem with a specific model.

So, i use the lenovo preload programs, i ran System Update to get the latest updates for all the lenovo programs and the power scheme of the power manager is default. Anyway the problem occurs.

This is my computer right now

Going into stand-by and wake up solves the problem. Till now this did the trick every time.

I'll try if closing and opening the lid without having any action asigned to this will do as well.
Anyway i want to get rid of the problem reliably.

Hope we can solve it

I have the same problem.

I assured to have installed the lenovo preload programs, i ran System Update to get the latest updates for all the lenovo programs and the power scheme of the power manager is default. Anyway the problem remains.
As pleased in message 52 by cleo_lenovo i opened a new topic with my notebook specifications.

Hope we can solve it there

Some admin deleted my topic and moved the post to here.

So sorry chaugi for offering my system as well now.

In between I found out that closing and opening the lid without having any action asigned to this arranges the problem once.

And when coming from hibernation i can preview if the control works:

- if the brightness bar occurs once and then disappears everything works fine.

- if it doesn't occur, brightness control doesn`t work.

So maybe theres some control component that should be reloaded after hibernation but doesn't do reliably?

Update: Opening and closing the lid makes the control work always. turning off the display by hotkey and turn it on again does never.
