This should not have anything to do with the operating system installed.
Try shutting down the laptop, leaving the battery in and the power cord
plugged in. If the battery has not gone bad, this should recharge the
battery in a few hours. Then, unplug the power cord and turn on the
laptop. If it doesn't come on at all, you need a new battery; this is
what I suspect from your description. If the computer comes on, but
Linux does not run properly, post back with details, e.g. the
power-on-self-test (POST) runs normally, but it cannot find a bootable
To add to Marvin's reply, a lot of Dell laptops have the battery indicator light flash orange/red in some repetitive fashion if the battery falls below a certain level/ability to hold a charge - it's somewhere around 35% of the original battery charging capacity. So if you see the constantly blinking light on your laptop, your battery is kaput.
