Appearance: The battery looks visually very promising, and is similar to the original Toshiba very. The workmanship is very good. The battery fits in the notebook tiptop.
Detection: By that I had major problems at the beginning. The battery is simply not recognized! Bottom right of the taskbar status "No battery detected". I then made the following:
Shutdown 1x notebook battery removed, rebooted then shutdown (without battery with power) again, then the battery in, then start up again, then my battery was not detected again, clean shutdown, again 1x boot without battery, then go down again , battery clean, re-booting, and then he was suddenly recognized, but not sustainably - he lost again and again the connection, or is not recognized. This is normal I think, because the battery was something of mega empty, that he had to be times as revived. For the reason Just boot a few times without, and suddenly he goes to "2% remaining, etc ..."
According to Info window currently extends the battery in sleep mode for 2 hours, in Hochleistungsmods for 1h. But could nocht make any specific tests, because the battery is in operation only since 2 days.
I'll write later time if and how the battery life has changed.
Conclusion: The battery is really great for the price, 5 star there when he has proven time really in the long-term test.
