Laptop computer issues

[jen0314]

I have a Compaq Presario CQ57. I have issues sometimes with it not turning on. I will leave it alone for a few hours and it will come on again. The time and date will be set to the last time I had it on. I don't understand what is going on. Any helpful answers would be great.

How old is the laptop?
If its old (older than 6 months) have you ever blow the dust?
If time and date resets its usually a matter of the cmos battery
I know the laptop isnt the same but you can look at this video to know where to look for the battery -> https/www.youtube.com/watch?v=g_s8tdcjp70
