Re: screen wont light up

welcome to the community.

 

sorry you're having troubles.

regarding the beeps... what is the exact pattern, long/short, repeating, etc?

 

cheers.

ok.

have a look at: http://support.lenovo.com/en_US/diagnose-and-fix/detail.page?DocID=HT035729

1-3-3-1 is listed as a dimm or system board issue. if you have another memory stick, pull out the existing and swap it in, then try booting again. if it boots, then it was likely the original stick. if it doesn't, it sounds like you've got a system board issue. are you still under warranty?

Re: screen wont light up

ok.

i'm not confident this will have any effect whatsoever, but you can try it:

  Ensure nothing is plugged into the computer

  Remove the battery

  Press power button 10 times

  Press power button down for 30 seconds

  Press power button twice

  Attach ac adapter

  Press power button once. PC should come up. Perform normal start up. Everything should be fine.

  Shut down and reinstall the battery

Re: screen wont light up

all it did was repeat the same type of beeps...i sincerely thank you for your help...question-is it the mother board that is messed up or perhaps some thing else? and will it cost too much to have it repaired vs.buying another of the same?? thanks

Re: screen wont light up

well... without some known good memory to swap in and test, it could be either the memory or the system board, if the beep code is to be trusted.

 

if it's just memory, then it's cheap. if it's the system board, i don't really know what they cost, used or new. couple that with labor to tear down and replace and it might well be cheaper to buy a new laptop. if you're electronically handy and can find the right board used, it might make sense to go that route.

 

anyway, while i can't really offer more info, there are a number of hardware gurus on the forum that will likely see this thread and be able to weigh in more definitively.

 

sorry...
