My laptop powers up for about three or four minutes then shuts down again. whilst it is running, it works perfectly normally but the battery does not charge. My theory is that it is the power supply that is faulty and not the actual laptop. Can you add your opinion and also let me know where i might source another power supply. Thanks, Robert
ps it powers up without the battery installed as well as with it installed.

The problem with your laptop is the battery itself. You said that when you plug the adapter it turns on. Here is a good troubleshooting step you can do. remove the battery and plug the adapter to your laptop, power on the laptop and check if it has the same problem and if not, that means that your battery is the one that is faulty. If the problem occurs even if the adapter is plugged. that means you need to replace the adapter. thanks.

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.
Try to cool the laptop in the sense, do not use it for some time, approx two three hrs then try to re install...
But if your laptop is old then the problem could be because the fans working beneath get old and do not run upto the mark..usually they have two fans i believe...maybe one is conked?
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
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!
Hi James, replace the fan or If it's still under warranty have it serviced. Suggest you stop turning it on until the fan is replaced. It could be the fan cooling the CPU. You don't want it to fry.
The shut down process is normal when over heating is detected by the system.
