Hi

Yesterday I saw a very weird phenomena. The battery monitor showed me 90% charged (usually it shows 100%) when it was plugged in the electricity. So, I decided to experiment a little bit to see from where the problem is. I barely work with the battery. When I needed it, it worked fine. The laptop is 2 years old.

My first experiment was to plug out the electricity. The laptop closed immediately. The battery is not recognized? The charging system doesn't work?

Today when I tried to open the laptop without electricity, it didn't turn on. Either the BIOS didn't recognized the battery or something else. The battery was supposed to be 100% charged.

I plugged it in the electricity. Now it showed me 89% and charging. But this 89% never grew. This time, I decided to pull out the battery. Now without battery it shows me 89% and charging. I don't know what's wrong.

I have upower-pm-utils installed. Not upower. I also have lm_sensors too, but the latest doesn't monitor battery. Anyone knows what's wrong? For starters it looks like there is some software problem (because it shows charging even when there is no battery). On the other hand, the fact that it didn't turn on without electricity, indicates maybe problem with battery/bios. The battery is samsung li-ion AA-PB95C6B.

I see the blinking orange led for charging.

Now I connected the battery and it shows me that there is no battery present. VERY, very weird.

Unfortunately the most likely culprit is...

It's dead, Jim.

What you describe sounds very much like a really broken battery, or your hardware no longer recognizes the battery. It takes quite a bit of battery power to even get through BIOS so likely it didn't even get that far during boot (or did it?).

See if you can find someone to borrow a battery from to tell if it's worth it to replace (probably not, according to most people...)

You are probably right. I tried today to boot again (after charging ~1hr). It doesn't turn on at all without electricity. It didn't reach the BIOS either. I have a friend who has the same laptop, I"ll check with his battery.
