I have a lenovo laptop its about a year old and it when I turn it on all the boot lights come on then after about 10 secons it turns off nothing boots to the screen. ive tried to boot with just the battery and the same thing happens. The charge lights on the battery show it has a full charge. I would really like some help with this before I have to take it in if its just something simple to fix.

Which model of Lenovo? What is the configuration? Hard drive brand and size, memory, connection?
Has it had any impact while the computer was powered up?
Lenovo laptops are usually among the most reliable, but there are a couple of models that need work.
Try booting to safe mode to see if there is a difference. As soon as you press the <ON> button, press the <F8> key repeatedly once per second. If it works, you will boot to a low resolution screen that is a bit difficult to read. That will tell us a few useful things about what do to next.
