How can i fix my yamaha keyboard, PSR 270, so that it keeps it memory after being switched off at the plug/mains?

i used to have a psr 280 and the memorey used to wipe itself when switched of at the mains. i think the only way to save your data is to save it on your pc. i upgraded to a dgx-220 and i cant fault it. the dgx-220 will save all your data when turned off at the mains
