Info: Laptop is a dell latitude e5400 in use since at least early 2010, probably longer (issued by an online school)
Problem: Laptop has been shutting down with absolutely no warning. Occasionally upon reboot, the screen will not light up. Each time, one of the following three things has worked: Taking the battery out, putting it back in, rebooting again; taking the battery out and rebooting with just the brick; and, this most recent time, taking the charger out and rebooting from just the battery.
Other issues: Odd noises coming from the inside (probably the fan, as I just used compressed air on the fans due to frequent dust build-up) frequent loss of wireless internet connection even though other devices have absolutely no problem connecting and staying connected
Is there a fix for any/all of these problems that don't involve prohibitively expensive part replacements? Just a replacement battery costs $40! Thanks guys!

If it worked flawlessly on AC adapter only, then that's a start. I would worry first on the hardware part before going into network disconnection. When heat builds up, the CPU fan would kick in to provide heat dissipation. If not enough then it would shutdown. Check Event Viewer on your Control Panel for this information. Usually they are red with X mark as critical.
