Tip & How-To about Computers & Internet

My laptop doesnt Hibernate.

Most of the times a laptop would fail to hibernate due to an OS Driver Management Issue.

Even after doing Lot of Homework on setting up the Hibernation settings, if your laptop is not hibernating, Check for the Posibility of having a new device attached to one of the ports or a new application installed.

Usually when a hibernation process starts the Kernal would enforce the App Manager and the HAL to communicate with the backend process and the Driver programs to close down the operation and write back the system state logs to the hiberfil.sys.

The Applications and Driver programs running on a windows system should abide to the WDDM Framework. (Windows Device Driver Model). A device driver which is running on a windows system if not written to follow the WDDM Framework shall refrain from closing the ports and getting to the hibernation status due to which the kernal will not be able to close the programs and return to hibernation mode and this keeps the system running live.

So check for any such new applications running on your Windows system and also check for any Wireless device like (Mouse or Keyboard) which is not Windows Compatable and running on the system.

Hope this solves the issue. (Good Luck).

Try going into your control paned and disabling your hibernation settings under the power management section. I've seen hibernation cause this issue many times.

Laptop does not wake up after sleep

I see this problem a lot, in most cases it is a problem with the ACPI driver. The easiest solution is to make changes to the Power Management settings. What happens is part of the computer goes to sleep and part goes into hibernate. Unless I am trying to conserve battery power I set the system to always on and use the screen saver to protect the screen from damage. If I am looking to save battery then I still set the screen to always on with the black screen saver and set the rest of the settings to sleep with no Hibernate settings. Hibernation is nice but really does nothing more than write data to the hard drive so the system can restart and you do not save anytime allowing it to operate. It causes more problem in configurations than it solves. In fact the only machine I might consider using a Hibernate setting on would be a server.

when my m45-s331 laptop is turn on for a long time, if i put the monitor off, maybe in not be turn on again and it's brightness become very low and hardly it can be seen! what should i do?

if you're using win xp, try to check the power option.(click start, go to control panel & power management/power option).from there, you have an option to adjust your screen brightness settings everytime you wake up your system from sleep mode/hibernation mode.
other option, you can update your video driver. here's the link http://www.csd.toshiba.com/cgi-bin/tais/support/jsp/modelContent.jsp?ct=DL&os=&category=&moid=882862&rpn=PSM40U&modelFilter=M45-S331&selCategory=2756709&selFamily=1073768663
then choose display driver. download and install it. It will update your video display driver. It might help to improve your brightness issue.
Good Luck,

navigate to a web page watch video - laptop switches off after 3 mins - stays on for hours otherwise

Sounds like the laptop is going into hibernation. Have a look at power management to check on what hibernation is set to.If you are watching streaming video then the cpu etc are not doing anything, only your graphics chip is working and as the graphics chip is not polled by the power management system, it thinks you have left the laptop and hibernates it !! Increase the delay for hibernation or turn hibernation off. Just remember to close the screen when you leave the system unattended as this will also initiate hibernation..
