I've had this laptop for around 4-5 years now. It's been acting a little strange as of late (eg. it would make an extremely loud noise before booting for around half a minute), but now it won't turn on.
The charging light comes on when it is plugged in, and the power light will come on when the power button is pressed for around five seconds. Then it just turns off. When the battery is removed, the charging light is no longer on. The power light will do the same thing when the power button is pushed. The computer is silent.
