Help Power on button

[fishphone]

Since updating to Gingerbread my phone now takes a really long press of the power button to switch it on from hibernated state. This is when using fastboot option. It only happens if the phone is not on charge (i.e if connected to charger then the button responds immediately as it did before the update). Just wondered if this is normal or if anyone else having same issue. I do have one of those supposedly 1800mAh batterys from obostore, so dont know if this is related.
