If it's not an "LCD" laptop, meaning the display is backlit with white LCDs instead of CCF (cold cathode fluorescent) it could be the inverter (think fluorescent light ballast) or, less likely, the back lights themselves are going out. If it's the inverter (90+% of the time it will be) it's a fairly easy replacement. Search on (your model laptop) + Inverter for pricing and instructions.

If it is an LCD backlit display, then it's either something in the system power board, the display itself, or the wiring from the board through the hinges into the display.

My pc automatically get start on plug on .and then it suggest me to press F1 to Continue. when I do this it takes incorrect date and time how to restrict it.I want to start it with start button on cabinet


There can be many reasons...
  • Your BIOS setting is not correct.
  • CMOS battery is down(Most probably).
  • both
You can open the BIOS setting page by pressing keys like DEL, F10, etc. depending on your system's manufacturer at computer startup(post screen). There are lots of wakeup options check them properly.
One of the option is "Restore last state of power Button on failure" which can turn on your computer without touching the power button. you should check these options.


And it suggest you to press F1 because your system's date/time is not configured properly. You can also set Time/date in BIOS also.
If your BIOS Battery(CMOS) is not weak or dead then after setting these values your computer should start properly.
And if your BIOS battery is dead then all the settings will be lost(date/time etc) after a restart and you will face same problem again...

Try changing the Power-button option and Date/Time in BIOS and see if problem persist....if yes then you have to change COMS battery that is on your Motherboard.

Phaser 8560N prints multiple pages when powered on


This was due to the TFTP (PXE) setting on the printer set to on. No more wasted paper at startup/wakeup after changing setting to off.

No display


Usually the keyboards have an fn key. Press fn + the key that has the sign of moon at the same time.

Also you may try to close your laptop and open it up and see if that will wake up the computer. Somehow your power setting on battery are messed up.

Hope that helps you.
