Random computer reboot

If you haven't blown the dust out of it in a while, try that first. Concentrate around the CPU heatsink. I use a leaf blower to do this, but a vacuum cleaner that blows air or compressed air works, also.

Do NOT let the vacuum cleaner (I don't know about leaf blower) be close to the circuit board.  It'll create harmful magnetic field.  What I do is use a vacuum cleaner and a compressed air gun.
Use the gun to shoot and use the vacuum to "eat" all the dusts that fly out.

But, yes, clean the laptop if you haven't for awhile.

Hello!

They do make special anti-static vacuum cleaners (copier techs use them), so perhaps static discharge is the biggest issue.

As for EM fields, the end of a vacuum cleaner hose is usually 1-2 meters (3-6 feet) or more from the motor. The computer component most affected by EM would be the hard drive, and it would take a good bit of EM indeed to wipe out data through the case of a hard drive - which could be removed by the paranoid prior to cleaning, I suppose...
