Was the replacement battery fully charged?
Have you tried a different compatible charger?
On the front of the laptop there is a battery light (not a button).
When you connect the charger the light should show white if the battery is charging or orange if it is using the battery i.e. no charger connected.
If there is no light at all it is either fully charged or the laptop is in sleep mode or off.
Have you tried holding the power button for >10 seconds to force turn off the laptop in case it is in sleep mode and not responding and then try turning it on?
If still no good then there's a problem on the motherboard because it should show that the battery is charging even if the laptop is off. If the battery was fully charged the light would blink briefly when the charger is connected and then go out.
