I have a HPdv6000 notebook 2024 MB(RAM), with BT3 installed in HD. The problem is when I booted without the AC adapter it takes too long to start and recognize all the hardware that is in my laptop.

Usually, it works excelent when the AC adapter is pluged in my laptop, it taked 2 minutes to boot bt3, but when the AC is unpluged and the laptop its working by its self it takes about 15 minutes to start : and I have only this problem with BT3.

can somebody help me please.

thanks in advance.
