So how long does your notebook last?

The battery indicator for my notebook his 0 percent about 20 minutes ago, still waiting for it to die. How long does your notebook last once it hits 0 percent?


*edit*
Still up at almost 30 minutes/

*edit2*
Died at around 48 minutes. I neeed to learn how to calibrate it.
 
Mine states It has about 15%, then shuts off about a minute later. This is my basic Toshiba lappy, not my Dell lappy.
 
I turned off all the hibernate and standy options. It actually lasts a while at 2% or whatever it is. Atleast 30 min.
 
I don't have battery drivers so it won't tell me when the battery is about to die, it just shuts off on me, very inconvient at times.
 
That is user settable in Power Management. I really don't know what mine does because I use battery power only occasionally, . . . in fact, rarely. 30 Minutes after your zero read out suggests that you may not have calibrated your battery and it's power gauge.
 
I turned off the automatic hibernate alarm because I read somewhere that Li-ion batteries need to recalibrate about once every 30 full charges. It's an old Inspiron 1100, battery was supposed to be a massive 4 hours new, but now i'm lucky if it lasts half an hour. AFter 10 minutes, I'm at 10 %, I hover at 3% for about 15 minutes, and then I dropped to 0 percent where I remained for a further 15 minutes. After this experiment, I rebooted- no luck, power meter was still woefully inaccurate. I'm using an old desktop now, my laptop committed suicide- hopefully not linked to the 5 times in the last month i ran it into the ground battery-wise trying to calibrate the battery.
 
My battery is screwy. Lucky I have battery monitor in linux. It tells me the power consumption and battery capacity. It's a 38Wh battery that thinks it's a 21Wh battery. 😛 So after that '21Wh' drains to 20mWh it will stay there for 30-40 minutes, then the system will beep a warning and show 0mWh for another 20-30minutes. After that the backlight for screen will turn off but the system is still function giving me a few minutes to safely shutdown or plug in power and shutdown.

I've tried full drains to try to make the battery realize it's full capacity, but the best I've gotten is 25Wh. It still gives me about 3-4hrs so I'm happy. It's still great considering it's an old battery and old laptop.
