Now I have blinking power light when connected to ac adaptor with the battery but when I remove the battery still connected to ac adaptor no lights. and on pressing power button the all lights comes on for 2 seconds and go off(this is again with battery) a bit frustrated. I have stripped it down to mobo only still the same. Can Anyone help.!!!!

Is it a constantly blinking light or is there a pattern? My initial guess is something cracked on the motherboard. Unless you can get it to produce some type of diagnostic code, we have to assume the worse. If you do not see any physical breaks, it may be a simple solder joint somewhere and maybe a reflow of the board would fix it...but you may be better off replacing the board altogether.

 

My recommendation would be to take it into the shop or replace it altogether. Sorry. Maybe someone else will have a better solution. Keep checking in.

@Dave@Bytes appreciate your reply. But there is no pattern its just constant blinking and as mentioned only blinks when battery and power is connected, does  not blink with power only. Light is there definitely rules out bad ac adaptor or loose power pin, I m guessing its the worse,(as u said) but I m still trying. lol.

How far did it fall and was the AC adapter plugged in when it did fall?  It will not power on with just the AC adapter and no battery, correct?

      1) Does anyone know if Microsoft are going to produce a Windows 11? I have found only conflicting information on the Internet.

      2) I have found lots of Windows 10 books on the Internet. Any recommendations for a good basic book on Windows 10?

      We pre-purchased and pre-installed the game Shadow of War on our gaming PC through Steam this week only to discover it would not launch when we clicked Play. I wanted to post our fix here in case anyone else searching the Web for clues to this needs help. 

      Tried uninstalling and reinstalling the game (all 100gigs worth). 


      Tried rolling back the nVidia graphics driver.


      Tried cursing (made me feel better but did not fix the issue). 


      Scanned and verified the game from within Steam


      Ran sfc /scannow from the command line to make sure Windows was OK.



      I ultimately realized the issue was with Visual C++ Redistributable

      I had multiple version installed. Some we very old. I removed them all and installed Visual C++ Redistributable for Visual Studio 2015 from here and that fixed it. https://www.microsoft.com/en-us/download/details.aspx?id=48145

      If anyone else had problems and found different solutions, let us know.
