battery problem

After being on AC power all night and saying that the battery is 100%, when I unplug it after a few seconds it jumps to 75%. Then after plugging it in again it says it's at 75% charging (now 76..), as if it really DID loose all that much charge!

I've been using it on batteries a lot and I JUST discharged it last night, not to mention quite a bit in the days before that.

Also it might be my power setting, but does anyone know what power setting to go to stop it going into standby as soon as the battery gets critical?

edit: after letting the laptop charge again to fill up the extra 25%, I thought that it had charged all the way to 99% on the battery again but it just went down to 75% again...I THOUGHT it had charged up to 99% and would stay there but nevermind.

Fully discharge and fully recharge it a couple of more times. If it doesn't run for the "normal" time for an 8890 battery (regardless of the readings), consider RMA'ing it. My 14-month old batteries are losing potency but ain't kaput yet. Many other folks' have died long before that. For the last several weeks I've taken to removing the battery entirely when I'm on AC. Runs cooler and I'm not constantly "charging" the battery. If I lose AC it can't be any worse that fully discharging the battery, which I've done at least 15 times in the last year.

8890 Batteries

Hey all.

I'm pretty sure that the batteries used on our Sager 8890s are Nickle-Cadium. This suprises me as I figured that Sager would have used something like Metal Nickle Hydride, which is the more advanced technology and better performer.

Do you know if our batteries will suffer from being constantly plugged in all the time? You all remember the Nickle-Cadium batteries from before. How about recharges on a partially full battery?

Sager site states: "Smart Li-ION Battery". Isn't that different from what you have "concluded"??

Look at your battery and see what is printed on it and report back to us please.

We definitely have Li-Ions. At least I do.

Lithium Ions...

Heh, I'm not going to check right now. Sorry, I must have been thinking of something else. Yeah, now that I think of it. I think you're right. That and you all proved me wrong. Man i feel dumb.

Isn't Nickel Metal Hydride with the new microchips better than lith-ion?

Don't know about blinking green..but today I had my laptop in my backpack..I opened my car door and the backpack fell out plop..but it was very cushioned and I wasn't worried. When I turned it on a GOOD thing happened...the battery is actually not jumping around! It can hold a full charge now! Yay! While I don't recommend dropping your computer to fix a battery problem, try taking it out and putting it back in again...(I was scared to do that because last time I did I couldn't get it in and it was sticking out)
