Sigh.
Toshiba error codes are two-digit hexadecimal numbers. The codes are displayed by flashing an LED in two groups. Long flash ="1", short flash "0". First group is least significant digit.
Depending on the model, the error codes range from 00h to DFh.
Since the first group is two flashes but we've not been told how long the flashes are, the digit is probably "2" or "3". Yes, I know that 2h=2d=2o=2anyotherbaseyoucanname.
As a rule of thumb, suspect the power adapter, cord & socket for any 1Xh code. Suspect the internal power board & battery for any 2Xh code. Where X=0-F, not 0-X, DO'L.
Having said all the above, any combination of 2 flashes followed by 6 flashes doesn't seem to match a (common) Toshcode.
PJ, to waste your time, see if you can boot using any of the following methods:
Battery in, power cord out.
Power cord in, battery out.
Leave the battery out for some time. Repeat the above.
If the first method works for you, you can reinsert the power cord after the computer's started booting. If the battery pack and adapter are OK, it's probably a loose/oxidized connection in or around the internal power board.
