Thinkpads Forum

Okay, so here's the deal. I've been using my Thinkpad 600E for about a year, and everything's been fine up until now. It happened gradually. Originally my battery held of a charge about over 2 hours. A few weeks ago it went down to 20 minutes without an AC adapter. Then, I couldn't even use it unless it was plugged in. After a few days of it being pluggd in constantly, the moniter started flickering. Then it went off completely. The computer would still start, but you couldn't see anything. Finally, the inevitable happened. It won't power on. Nothing. With it plugged in the power light/CPSLCK/SCRLCK/NUMLCK flickers. Without it plugged in, not even that.

I've bought a new power adapter, thinking that might've been the cause. Nope. Now, my next step would be to buy a new battery, but I wanted to know if I should even bother or not.

Please help!

I had that Exact same problem, My computer quit reading off the AC, i bought another AC just like you did, no luck, don't buy a new battery eaither, here are your 2 ONLY options.

Your CMOS capsiter chip blew, have it replaced for $200.00 by a company I know of.

Go to ebay, and spend $65.00 on a new motherboard, and spend $100
to pay a EBAY tech to do it.

or if your good enough do it your-self.

or send it too me, and i'll charge only parts and shipping.
motherboard $60.00-80.00
shipping 25.00.

I have been fixing and building thinkpads for 3 years.
and I enjoy helping people, so no labour charge.
Or I can even change your laptop too a 600X
$70.00-$90.00 500MHz SSE MMX

or if your good enough do it your-self.
contact me by email if you kneed me too do iy for you.
regards.

I didn't know about the CMOS capaciter! It could be the DC/DC power supply in the computer itself though. That powers the LCD and motherboard. Could be that the LCD section (the highest voltage) went first then the rest followed. I'd try the capaciter first. If it isn't a surface mount should be easy enough to clip and solder in a new one, if the location is known. The power supply is a separate board, it's not hard to replace. I'm just glad these things are made that way (modular) instead of having the power supply as part of the motherboard to save a few pennies! A fellow just asked me if his Gateway desktop could be fixed after lightning ran in on it. I told him to pull the power supply and change it. He took the case cover off and reported that there didn't seem to be a separate power supply. Oh well! I told him to call Gateway, the motherboard might be available.

What do you meen a second power supply board? the think-pad has every thing on 1 board. all laptops should. descktops have the room, but not laptops. I do-not know where the CMOS capaciter chip is.
And he may not know that much about computers.
Just replace the motherboard.
