My son used my laptop Lenovo 3000 n100 and let the battery run down not in time to shut it down. Now it doesn't power up, not even plugged to the power supply. The only button that lights up is the one with the Z. I don't know if it's the battery although I doubt it. I would like to know what usually is the first thing to go, if the processor or the mother board. What can I do?
I had posted the Aug 19, 2008 comment about having this problem twice. I tried a new universal AC adapter, and it worked! (new adapter is a Targus APA63US) Now battery is charging and laptop also runs on AC alone. So perhaps it's an adapter problem instead of a battery problem. Get one at a store with a good return policy, so if it doesn't work for you, just return it. And if it does work, then happier days. I've had mine about 2 weeks. So far so good, though with what I've learned about Lenovo since having this problem, it wouldn't surprise me if something else goes wrong, or if the damn thing just blew up, ha ha. Also, this adapter set me back about $100 that I really should not have needed to spend! arrgggh ...
Cheers and Best of Luck and hope this helps other frustrated Lenovo owners!

If you are running on battery power and it powers off, then the battery is not fully charged or the battery is worn out or faulty.
Rechargeable batteries have a finite number of charge and discharge cycles and after 2 or more years they will lose its charge capacity until it will not charge at all.
A new battery will solve your problem provided the charging circuit in the laptop is OK.
How old is the laptop? You may have suffered one of two things? First of all, if the hard drive will not boot back up, even after using the recovery discs, then that would explain it powering off. I have seen this happen on old desktop hard drives.
Next, try to get the transformer or adapter tested. It may not be putting out enough amperage to run the laptop.
Hi.. I have a temporary solution to your problem. I had the same problem. Remove the battery and the ac adapter from the laptop. Just reconnect the ac adapter without the battery and switch on the lap. Presto.. Problem solved.. It doesnt power off anymore unless u remove the ac adaptor. Usefull if u hav needed files n want 2 create a backup. Still i havent found out a permanent solution to this problem. I suspect its a motherboard fault
