Numerical time versus clock icon on the status bar

The Android "M" Developer Preview's second release was released just a short while ago, and we've already discovered an outstanding new feature: the ability to individually enable or disable icons in the status bar. In fact, if the only icon you want is your battery and clock, you can have that now - everything else can be removed!
To access the settings, you'll need to have developer options enabled. From developer options, there's an option to enable the system UI tuner, which then appears in the main settings tree near the bottom of the list.
There are also other changes to the tuner - you can show your battery's remaining percentage inside the battery bar now, which is also very, very nice and something we love very much.
What exactly demo mode is, I'm not sure - it appears to set all the status bar icons to their "on" states, but only certain ones. Demo mode, as one of our intrepid commenters pointed out, is probably for developers taking screenshots or videos of their apps. It forces notifications off the status bar and sets the bar to display cell signal, 100% battery, and locks the clock at 5:20 - so you can have a consistent status bar. Very handy.
But either way, these two other changes are amazing.

You phone has it's screen rotation locked so if you turn the phone on it's side the display does not automatically turn, great for reading in bed. Double clicking your home button so that currently running apps are shown then keep swiping these icons to the right until your iPod controls appear, you should see an icon with a circular arrow. Click this.

The computer doesn't know if you have made changes or not... until it talks to the device... so, instead, how about shutting down ActiveSync or changing the connection settings so that it can only sync when you want it to.

Have you tried a Master Reset?

Hold the red power (end call) button, take the battery out, replace the battery. You will be prompted if want to reset the phone with Up for yes, and Down for no. This is how to completely wipe the phone to the state it was when you first bought it. Please make sure to have any custom applications and data on the device (other then data that comes from outlook) backed up. When you resync it to outlook, your contacts, emails, calendar etc will come back.

If after a master reset, the phone does not power on, then you will need to get it replaced, as this is a definate sign that the mainboard inside the motherboard is bad.

PF means power failure.
For short outages the clock may still have correct time
(there is a battery backup for that), but the PF will
be displayed. Setting the clock will clear the PF
indication.

Press 'clock set-start' button, (under clock display)
enter time with numeric keypad,
press 'start' button. (to right of clock)

do a hard reset.

can you tell me where i can find a manuel for 700w palm, also i cant hear the phone ring always getting messages but it never rings.

The battery might be bad you can go and have someone check the battery at any electronic store with a voltage meter.

hold the red power button down for 2 sec then it should say welcome if not then take the battery cover off and to the left of the battery is a reset button you can press with the sylus

Back up your data and do a hard reset.
