CMOS Reserve Battery on Inspiron 600M

This question is answered

As noted it's an old 600M Inspiron that stopped working about 2 yrs ago when I turned it on and after a few seconds the screen turned orange and shut down.  A few months later I hooked it up to an external monitor and nothing.  I mean when I power on the green light turns on and shuts down after 9 seconds.  The battery is good but I replaced it anyway but still the same problem.  After sitting on a bookshelf for 6 months, a friend turned it on and had it working for about 90 min.  I was not there.  He suggested unplugging and replugging the cmos or reserve battery found in the side of the main battery compartment.

It was tough to get out and I broke the tiny white plug (wired to the 3 small round batteries wrapped in plastic) in the process.  I ordered a new reserve battery on ebay for $2.99.  I could not get the plug all the way into the socket.  It's a tight fit so using pliers I squeezed it in. 

Any suggestions would be appreciated.

  • Even a dead CMOS battery won't prevent power up.  Reseat both memory modules (remove and reinstall), after disconnecting the system from AC power and removing the battery - hold the power button for 30 seconds.  

    If that doesn't get the system going, replace the system board.

  • Thanks ejn63.  Do I have to remove the keyboard or bottom of the laptop to get access to the board?

  • Everything inside goes in from the top.

  • Never mind, I just found out how to get to the board.  Thanks again for your help.  I may not get to it for a few days but when I do I'll let you know how I made out.

  • Ok, but the directions show only removing the 1 cover on the bottom to get to the memory module.

  • That's all you need to do to reseat the memory - but that's a longshot.  It's far more likely the system board is faulty.

  • Thanks ejn.  You're right it was a long shot.  I reseated the two modules but the pc still does not turn on.  I'm not sure it's worth a new mother board but I do appreciate your help.
