Fix a laptop that does not Boot except in Safe mode

Any change related to graphic card (programmatically or manually )  on “brightness” during the boot process or even after boot causes boot immediate shutdown this can be caused by having different power profiles for with power or with battery 

Change of resolution after boot is fine but must return to original windows default card resolution to prevent change of resolution during boot

Setting and staying with basic video that system boot with is necessary

There should be no difference in power profiles

Enabling of Wireless LAN during boot process leads to shutdown

Enable  Wireless LAN after boot and disable before shutdown

therefore nothing should change during the boot process

Power cord must be detached during boot process.

Slowing the processor speed during shutdown and boot seems to be not effective

delete all uncessary apps

remove clearly all past virus killer

Stop unnecessary services

windows+R

run msconfig

Base video is what is important

after successful start

a bat file that must be run as administrator afterstart.bat on desktop

cd \users\amir\desktop
rem powershell -ExecutionPolicy Bypass -File “\users\amir\desktop\Set-Resolution.ps1” -Width 1366 -Height 768
powercfg -attributes SUB_PROCESSOR CPMAXFREQ -ATTRIB_HIDE
powercfg.exe -attributes sub_processor perfboostmode -attrib_hide
powercfg -setdcvalueindex scheme_current sub_processor procthrottlemin 100
powercfg -setactive scheme_current
powercfg -setacvalueindex scheme_current sub_processor procthrottlemax 100
powercfg -setactive scheme_current
netsh interface set interface “Wireless Network Connection” admin=enable
netsh wlan connect name=”371newnet”
powershell (Get-WmiObject -Namespace root/WMI -Class WmiMonitorBrightnessMethods).WmiSetBrightness(1,50)

 

 

before shot down a batch file to slow down power consumption similar to safe mode beforeshotdown.bat on desktop

netsh interface set interface “Wireless Network Connection” admin=disable
powercfg -setdcvalueindex scheme_current sub_processor procthrottlemin 5
powercfg -setactive scheme_current
powercfg -setacvalueindex scheme_current sub_processor procthrottlemax 40
powercfg -setactive scheme_current
powershell (Get-WmiObject -Namespace root/WMI -Class WmiMonitorBrightnessMethods).WmiSetBrightness(1,1)

rem powershell -ExecutionPolicy Bypass -File “\users\amir\desktop\Set-Resolution.ps1” -Width 800 -Height 600
rem bcdedit /set {current} vga yes

 

to make it easier to run just create shortcuts and during the shortcut making  make their property to run as admin

Create a power shell script on desktop if resolution change is needed
