Hi all

I'm using a thinkpad T60. I think my battery is out, I've been checking it through the ThinkVantage and it said battery ok but should discharge and recharge. I did that and it was ok for a few weeks but power gauge always says 80%-90% and less than a hour, it goes into hibernation.

Now, without AC, my thinkpad can't be switched on. I leave the ac on while the battery is still attached to use it. The battery icon is orange and blinking. When I've shut down, I remove the ac plug. I've never removed the battery before since I've used this thinkpad 4 years ago.

Is this harmful to my thinkpad, all my data and stuff?
I'm reluctant to remove the battery in case dust gathers around the exposed portion. I'm also reluctant to buy a new battery as I'm thinking of getting a new netbook, those 10" type of laptop.
What's the best way to manage and keep using this thinkpad without a new battery, or is it a big NO NO???

Please help, I'm not very IT savvy. Thanks in advance!

It sounds like the battery is still functioning, albeit at a reduced level. That means that the battery itself is not seriously damaged inside and has no internal shorts. It would be safe to leave it in.

As far as data and the system go, it really has nothing to do with it. Even if you leave the battery out, your data is safe on the hard drive and does not need power to be maintained.

Your unplugging it when it is not in use is a good idea, too. It may extend the battery's short life by not trying to charge it all the time, and you do not need to worry about it overheating (the battery or the charger).

I had my battery in all the time for two years, mostly while plugged in. It recently started going from 100% charged to shutdown in about five minutes. Needless to say, I replaced it. I now do not leave the battery in except when I am charging it. Not really a problem for me, except when I want to carry the notebook into the other room to print, or when the power goes out unexpectedly. I suppose I could configure the printer for wireless, but it seems like an unneccesary expense right now.

Hi Elvandil

Right now, I cannot power on the thinkpad without ac plugged in at all. I've plugged in ac to power up.

When I move my mouse over the battery icon in the notification area 'battery power gauge', it says '99% remaining. Irreparable damage to the battery has been detected. Replace the battery with a new one'.

May I just leave this battery attached anyway? Thanks for advice.

Well i think you should start on saving up for a new battery. It's better to solve the problem instead on letting it that way. Your laptop might end with further damage.

Yes, I wouldn't worry about it if you only plug it in when you use it. The battery will never recharge. It has probably developed "memory" and thinks it is full at a very low level.

If you don't want to buy a new one, and the machine runs fine, then the battery is not shorted or draining the CMOS battery and it will be fine.

Thanks all for your response.

The only reason why I'm reluctant to remove the battery is I don't want that area without the battery, exposed with crevices collecting dust and hard to clean.

Hi Elvandil

How would I know if the battery is shorted or draining the CMOS battery? Appreciate your help!

It would be nice to have a simple cover for the battery space. I suppose there is always duct tape ....
