NB550D - battery icon does not always reflect the proper balance of time
Posted: 08-Oct-2011 03:51

I have just recently purchased an NB550D and I must say that at the outset I am very happy with it. It does tend to be a bit slow but I can live with that.

My problem however is that the battery icon does not always reflect the proper balance of time. For instance after a full charge it may show 9 hours remaining but after a shutdown and restart it will may show 75% and 3 hours remaining. If I shut down and restart it may show 75% and 6 hours remaining

When I first started the unit I allowed it to fully discharge (through use) three times as was suggested by the salesman at the store but quite candidly it doesn't seem to have made one scrap of difference!

Any advice will be appreciated.

Regards

Remaining time is not credible value of the battery state - it depends on actual duty of processor and the program wich estimates this sometimes shows wrong that time or corrects this after a while. Percentage of charge of battery is much better factor to use!

But in case your battery loses from 95% to 75% after restart indictates that's something wrong with the battery or program... In my NB550D after restart (pause for 1 day) the battery loses only 2-3% .

Hi

As Tom said, the battery working time depands on the notebook usage.
The battery time can change always.

Furthermore I would recommend calibrate the battery to ensure better performance.
You should charge the battery until the led would switch to green (blue) and should discharge the battery completely until the notebook would shuts down automatically.
This process should be repeated several times.

Thank you PauPau and all respondents I have since discovered that my 3G wireless Internet connector uses a great deal of power as do USB sticks that are connected. I checked with no connections active and the percentage was up around 93%... at the moment it's about 85% and holding. I have discharged the battery three times as suggested.

Thank you all for your help and useful advice.

Regards
