I bought a laptop battery for my 10 year old Vaio laptop from an eBay seller. It started up fine when I initially booted up my laptop. But when the power meter was in the 52% remaining neighborhood, the system shutoff. I don't mean hibernate, I mean it was like someone pulled the plug (if it were running on AC power). I booted up again on AC power and let the battery charge to 100% again, then I let it run off the battery with the AC power removed. This time it shut off at about 72% power remaining. The best it will ever do is stay on until about the 30% remaining mark. I contacted the seller and this was the response,
"Please try calibrating it first by doing the following steps:
- Charge the laptop up to its maximum capacity. Leave the device plugged for two hours or more.
- Disconnect the laptop from AC power. Disable any means in the Power Options for the laptop to sleep or go into hibernation before the battery charge is depleted to. Use or leave the laptop on until the battery is depleted to 3% charge, in which the computer automatically enters hibernation.
- Leave the laptop in hibernation state for five hours or more.
- Charge the laptop again up to its maximum capacity."
This seems a bit hokey to me. Why would a new battery need this much attention?"
Thanks for your reply,
