Use the T43 while battery is being charged...

Is it advisable to use the thinkpad while my battery is being charged...and how long does it take to charge a 6 cell battery to 100% power...

Best information I've seen yet on Lithium Ion batteries. While there seem to be differing opinions, this one makes the most sense to me. Also I have read simular information elsewhere.

Any IBM laptop I have ever used (back to Windows 3.1) would work while being charged. It has never harmed an IBM laptop to be used while charging, at least so far as I know. The only "laptop" I had(have) that would only charge while off is my Toshiba Libretto Model 50. ... JD Hurst

I agree. It would be possible however to run a laptop off of an UPS, in which case you would still have data protection. Personally I just leave the battery in - especially since I don't have an UPS.

Ah sweet confirmation. "When using a notebook computer running from fixed line power over extended periods, it is advisable to remove the battery and store in a cool place." So detach those batteries and refrigerate them when docking the laptop to use it as a desktop.

However, does any know if the IBM li-poly batteries are the "thin film rechargeable" type that has been shown to provide more than 10,000 cycles? Since I just bought one I certainly hope so.

Sweet confirmation???
I clicked the link and nowhere do I see the passage that you put in quotes. Instead I saw:

"Removing the battery from a laptop while it is plugged in is against manufacturer's recommendation for many laptops as it can cause permanent damage to the laptop since the power supply is designed to output a voltage assuming a battery is present. Therefore, when removing the battery from a device when it is plugged in, be sure that it is in an acceptable mode of operation."

Li-ion batteries irreversibly lose approximately 20% capacity per year from the time they are manufactured, even when unused

Every (deep) discharge cycle decreases their capacity. The degradation is sloped such that 100 cycles leave the battery with about 75% to 85% of the original

wait, so i should use my battery because it breaks down anyways. but i shouldnt use it heavily because it decreases the battery life when i "deeply discharge it"?



wtf?

dammed if you do, dammed if you dont?

On the Battery University (?) website is suggests (among other things) to:

"Consider removing the battery from a laptop when running on fixed power. (Some laptop manufacturers are concerned about dust and moisture accumulating inside the battery casing.)"

Anyone know what IBM's advice is for whether or not to remove the battery when using AC?

Good news! You won't have to look very far to find it. It is the sentence just directly above/over/atop the very one you copied and quoted here.

enjoy!:D

p.s. I don't think anyone suggested removing the battery while the unit is plugged in. The question was whether it should be removed when using the unit on AC power.

If you value your data and the integrity of Windows, you will run your laptop with the battery always installed, or with the AC plugged into an UPS for emergency power.

EDIT: P.S. I would think this would especially be the case if you live in a lightening prone area such as Florida. I've heard that Tampa is the lightening capitol of the world!

UPS? Where's the adventure in that. :D:D

p.s. Lightning capital of the western hemisphere..... :shock::shock: We just learn to save frequently.
