Ive had several laptops of various makes with these symtoms.
 The first thing I do is access the following and reseat the connectors
Processor,
hard drive
memory
cmos battery
On most occasions the laptop does recover and boots ok as before.

If it doesnt, then i do a substitution with known working components  of 
the above.
this latter procedure is really a technicans job.
If this doesnt fix it then it could be a corrupt bios.
Ive had this from swapping a component when the laptop was powered up.My 
inexperience on a thinkpad 600x.

The next step is to strip it completely and inspect minutely.
 Some thinkpads due to heat had warping motherboards and consequent 
seperation of foxcon memory connectors.
Reassemble and try again .If the fault is still there then its a 
replacement motherboard.
Wether you can find some laptop technician interested to do the above 
depends on where you live etc.
 
Needless to say Im a laptop dealer and repairer.
Hope this helps
Ted
