Hey, i'm wondering if anyone can help me, I got a insipron 1545 (I think) for my birthday last year july. A few times when i have started up my laptop the mouse has stopped working so i've restarted it and it fixed the problem. Last night it just suddenly stopped working! So i restarted the laptop..nothing, I am currently using my computer mouse and it's rather annoying! 

Is there anyway to fix this? Does anyone know how long a warranty is for and if this will cover it? Please help! I need this laptop for college and I can't be carrying a mouse with me everywhere I go.
