It goes in sleep mode and will not reboot. even

Remove ALL media, DVD, CD, USB, unplug, remove battery, plug in reboot. OR try to boot to safe mode, open the Control Panel, select Power Options, set to High Performance, Change Plan settings, set SLEEP and Hibernate to Never.

replace bios battery, reset the bios, insert required parameters after rebooting and when windows reboot change the time period for screen saver and hard disk shut down!

format it and reinstall all the driver cds...

Go into safe mode
Under settings, control panel, power options set "turn off monitor to never
reboot

I think this is not a sleep problem but the incorrect monitor settings were set. This will cause the screen to go black when the OS comes up. Boot in safe mode and change the display settings
to 640x480
OR
in safe mode, delete your monitor. When you reboot it will load a default monitor and you should be OK

For that when you power up the computer press F8 key then enter in enable vga mode .
Then go to display property and set screen resolution to 1024*768 then apply and ok.
if still not work then try safe mode then uninstall graphic driver and reinstall.
When you power up the computer press F8 key untill you see windows logo.
Let me know if you need further assistance.
Thanks for using Fixya.

go through control panel to Power Options, switch off the options to sleep/hibernate.

1st change tsmps to check
2/ chang ram to check.
3/ repaire it buy operating system
4 use rescue antivirous disk to repair

turn off everything and restart computer in safe mode,do this by holding down f8 as you reboot,then go in your setting and remove time limit on sleep mode.

I have a LCD panel it is connect to to the LCD. I need to change a setting on the computer to make it stop going into sleep mode, however, now that it's in sleep mode, how do I get out of that so I can make the change?

1. File manager in ipcsuite
/System/Library/SystemConfiguration/PowerManagement.bundle
2. Find the file:
com.apple.SystemPowerProfileDefaults.plist
Then rename it to:
com.apple.SystemPowerProfileDefaults.plist2

3. Reboot your phone
