Thinkpad - bad battery?
worker201:
Manual is depressingly unhelpful in this regard. For starters, there is no "manual". ie, there is no book that tells you what that blinking battery light actually means. I just assumed it was a dead battery thing because the computer dies without AC power. There is a "Service and Troubleshooting Guide", but it doesn't mention the flashing lights, it only suggests that if your battery is dead, you should get a new one. Thanks for that! RTFM, indeed.
Lead Head:
That is very surprising coming from an IBM/Lenovo laptop. I would expected them to have provided top notch documentation.
worker201:
Well, maybe they did, but I think I killed it. As you may know from previous threads, I wiped this thing clean and installed Linux the day it arrived. Most of their documentation is in the computer itself, or online but only accessible through their proprietary help system. I just downloaded the software, hopefully it doesn't require me to go online to find that information. The Windows machine is not allowed to go on the internet. Why? Because it is running Windows.

On the outside there is a single set of LED indicators, from left to right: Battery, AC Power, and Sleep. The Battery indicator will blink when charging, shows orange when the battery is low, and solid green when fully charged. The AC Power indicator lets you know if the AC adapter is plugged in, an added feature over the T4x series. Lastly the sleep indicator specifies if the notebook is in Standby mode; it also blinks while the notebook is saving into Hibernate mode and turns off when completed.
Goggle results.
Also badly translated, overcharging the battery will ruin it.
Question:I have a IBM T60 laptop. My IBM ThinkPad T60 battery life has been diminishing lately (around 2 hours when I used to get 4), so I left-clicked on my battery gauge, bring up the power manager, went to batteries maintenance, and did a power gauge reset. This is supposed to fully charge, then fully discharge, then fully recharge my battery.
Answer:Take out your battery from the laptop and keep it outside for a day then plugin back and try it!! impossible it kill itself suddenly!!! remember dont over charge your battery, it will make your battery weak very quickly!!and buy brand battery .
new laptop battery yingzi

One more hint. I sometimes recondition sealed ups batteries from work. We can't afford to buy new because the economy is in the toilet (lots of people are being let go in two weeks).
If you overcharge a battery you will get gas bubbles that separate the electrolyte from the plates, even on a sealed battery. That's what causes "memory" in NiCads. If you don't do it too long, it can be reversed by ***slowly*** discharging the battery and ***slowly*** recharging it a couple of time. Slow is the key, and not overcharging so long that the plates dry out from gassing.
Smart battery chargers limit the applied current so the battery sees no more than one volt over its current state. That prevents gassing/electrolysis.
