I was on it one day, it went into hibernation mode & I tried cutting it it on, I was banging it a little. Then when I plugged it into my charger, it wouldnt cut on & the light didn't light up. Banging it a little never was a problem before. I keep trying to turn it on but the light bulb symbol keeps lighting up blue.what does that mean? & I don't have an adapter, so please don't comment saying take the adapter out. I have a regular charger. & what's the main supply? I don't think I have that. My charger has no piece where you take parts out. Its a regular whole charger. I have the Acer D255. Please. & thank you. !
