How do I reset the Series 5MX?

If you find that you cannot exit a program normally, move to the System screen and select the List open files command from the
File menu. Select the program from the list and press the Close file button.
If this does not work, or if your Series 5 appears to have locked up, you can always perform a soft reset. This should restart
your Series 5 while preserving most of your information.
It is worth trying a soft reset if the keys on the Series 5 do not appear to respond, or if the Series 5 does appear to switch on
and you are sure the batteries are good (especially if the contrast adjustment still appears to work), but the screen is otherwise
· To perform a soft reset: gently press something like an unfolded paperclip into the reset hole, above the backup
battery location.
After a soft reset, any changes to open Word or Sheet files (or OPL programs) will be lost. Your other files on the Internal disk
will almost always be safe.
It is possible (although unlikely) that a program failure causes the reset to lose the information on the Internal disk; it could even
prevent the reset from working at all. If this happens, you will have to perform a hard reset.
· To perform a hard reset: press the unfolded paperclip into the reset hole as for the soft reset. Then, hold down
both Shift keys, and press Esc to switch on.
Important: A hard reset resets the Series 5 completely, and all information on the Internal disk will be lost.

Psion Series 5MX hard reset

General advice: Before you buy a new cell phone or new tablet, please try the following procedure to repair your device in a software way. First charge your battery, backup your important data if possible and in most cases take out SIM and SD card before doing factory reset. It is impossible to recover your data after doing a hard reset, so online backup is always important. For all of your data, a backup should be done on an external device, hard drive, raid system or media. With or without insurance, if your cell phone lost, damaged or stolen at least your invaluable data is backed up in a safe place. If you are about to sell your phone and you want to wipe your personal data, or if your phone affected with virus you have to do a hard reset. In some cases, you can delete the forgotten password or lock pattern from your device as well. All information is for devices with stock based ROMs. If you are using rooted device, always back up your EFS folder first, containing your IMEI info, etc.! Please also note, that a hard reset operation will not unlock your mobile phone's SIM lock or network lock, but it will remove the unlock pattern, remove the user password or PIN password (NOT the SIM card's 4 digit PIN code). Also note that the firmware version will not be affected in any way, it will not be downgraded, it will remain the same you are using and if you have rooted your device, root privileges remain also unaffected.
