i have the 2140 for a few months, but it came with 3 cell battery so yesterday i bought a new 6 cell battery. i swapped the batteries, pluged in the power adapter and it's been charging until half an hour ago (so around 24 hours). the problem is that after i unpluged the power adapter the charging led started blinking orange. it never happened before with the old battery, what does this mean? i'm on battery the last 30 minutes and it's still blinking.
and what do the blue and orange colors mean when charging? first it's orange, then it changes to blue, and in the end it turns off.
