Toshiba laptop won't turn on

[randallwellings]

Toshiba Portege Z20T-B. Shut down, won't turn back on. LED flashes Long, short, short, short, short, long..pauses for two seconds, then starts back with the long, short, etc. again...what am I to do..There is a power indicator, it is on.
Should this be a motherboard issue..how do I determine which one is at fault..the Z20T-b is a 2 in 1 and has a battery and operating system in top and bottom.

Question from randallwellings : "Toshiba Flashing Codes"

I have a Toshiba Portege Z20 which shut down and won't te-start. The only thing working is the battery LED which is flashing a fault code.
The flashes are long, short, short, short, short, long..pause for 2 sec. back to the long and repeat.
I have checked the adaptor..it seams to be working fine..any suggestions would be very welcomed..cheers
