Lenovo 3000 Notebooks : N100 Power Failure!

Have a N100 notebook and battery does not recharge and now runs on AC power but would shut off by itself very shortly after switching it on. Brought a new AC adapter and battery straight from the lenovo website, received it, but did not solve the problem. I called lenovo directly they are not sure what could be the cause of the problem. They never heard of this problem. Laptop is only a year or so old, and only use couple hours a day. Wondering if anyone have the same problem and had it resolve, I would appreciate any insights you can offer. Thank you in advance for you help!

    I have the same problem it is so annoying I turn the computer on and it shuts off randomly. It makes a strange sound when it shuts off kind of a click. the amount of time it stays on is completely random and I know its not over heating because the computer is always cold or room temperature never hot. my battery won't charge at all. I'm on power cord number 4 or 5 and the last one caught fire. they won't give me a new one though cause my warranty is up. this is battery number 2. my problem is very frustrating. I can never figure out what is wrong. I'm thinking I want to buy a different power cord from another company if there is one because maybe it will last longer. Any help would be greatly appreciated.

Radalin -
I've done a lot of laptop repair, and have run into similar issues with various laptops. What you've described sounds to me like a problem in the power circuit on the motherboard. There are a number of things that can cause this, and, generally, none of them are an easy fix - blown capacitor, bad power IC, bridged leads on a relay. If you have any experience working with integrated circuits, you can always test the power loop on the laptop with a multimeter. However, you may want to look into obtaining a warranty repair, or purchasing an extended warranty so that you can get a warranty repair; if there has been no user error(i.e. fluids spilled on the computer, dropped computer, left in excessive heat or humidity), then its a factory defect on the motherboard.

Hope this helps!

Welcome to Fixya!

You can run the computer by just using the power adapter. Take out the battery and turn on the computer just using the power adapter. If the computer wont turn on then possible problem would be the power adapter itself or the socket where you connected the power adapter to your computer.
You need to send the computer to Lenovo depot repair center for repair.You may try to use other lenovo adapters just to check if the adapter is the problem.

Thank you for using Fixya!

Lenovo n100 is 10 minut after power off.


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.

Lenovo 3000 Notebooks : N100 Power Failure!


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

Lenovo 3000 n100 won't power up


Hello,

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!
