PSR-A1000. When turned on, why does it display 'UNEXPECTED ERROR TURN POWER ON AND OFF hisysdwn.c/133/0'?

Sounds like it could be a bad power supply and/or bad internal battery. Hope it helps

It could just be a glitch, or a low battery, or a power supply problem.

Be sure to use the original adapter and still in good condition/normal.
Have you tried, at the time after 5 minutes then turn off, and then you restart immediately, the unit is turn ON again? Or is there a time lag to ON, after power-switch is pressed?
Errors like this one,may be due to defective adapters (works only for a moment, after being hot, stop sending voltage), and can also be caused by damage to the regulator section in PSR910.
To check this, it must open/disassemble the PSR910.
"Do not do this if you are not experienced in electronic repair.

At Yamaha PSR S950 keyboard, there is a setting "AUTO POWER-OFF" in the UTILITY menu.
This setting function is To prevent unnecessary power consumption. It will Automatically turns the power off if the instrument is not operated for a specified period of time. The amount of time that elapses before the power is automatically turned off can be set (default setting: 30 min.). The setting is retained even if the power is turned off.
At the PSR-S910, this function does not exist.

how to psr i425 recording data tranfar to computer ...plz reply

This looks more like a computer problem than a musical instrument problem.

I would do a factory reset. Search Google for: factory reset PSR 2100.

It will be holding certain buttons or keys down when powering on.
