Loss of data when battery goes dead?

A few questions from a pda newbie. I am concerned about loss of data when the battery is depleted. From what I have read it seems that the built-in ram is volatile while the external is static and will stay forever without power. -are all pda's this way? -When the main battery depletes to the point where the unit shuts off how long do you have before data is lost? -Is the backup battery just used when changing main batteries or does it take over when the main battery goes dead? If so how long do you have before it is dead? -does the backup battery recharge or does it have to be replaced? -with a fully charged unit how long can it be left off before data is lost?

The backup battery's function is to act whenever the main battery is not available, i.e. the main battery is drained, or the battery is missing all together (such as when switching batteries.) The backup battery is usually a standard watch-size battery and as such does not have the power needed to actually power the PDA for actual usage. What it can do is continue the power flow to your RAM so that no data is lost. How long the battery lasts depends on the actual PDA. Years ago I had a Cassiopeia E-100 Palm-Size PC and it came with a backup battery, I believe the manual said that the battery could hold the RAM contents for 30 days before going belly-up. So, as long as you attach a powersource to your PDA within those 30 days (or whatever time frame the X5 has), you should be fine. Just make sure that if you left it running on the backup for a long time to replace that battery as well. The machine will most likely tell you that, but as I don't work for Dell and don't have my X5 yet, I can't make promises. The battery, if it is a standard watch battery, should be available at any Drug Store, Department Store, Jewelry Store, and the good-old standby, Radio Shack.

A PDA is no different in many respects from any other computer. Backup, backup, backup. All your data should be backed up on the desktop or notebook PC, in addition, there are backup programs and memory card programs to back your data up on as well, SoftWinter comes to mind. Check out Handango I think. Remember most of your information is 'synched', so items like address book/contacts, calendar etc. are always on your PC, but if on the road and the unthinkable happens, as it usually does, your data will be backed up on the memory card.

-are all pda's this way? All PocketPCs are this way. I don't own a P**m so I can't speak to them. -When the main battery depletes to the point where the unit shuts off how long do you have before data is lost? Until the backup battery dies. -Is the backup battery just used when changing main batteries or does it take over when the main battery goes dead? If so how long do you have before it is dead? I've never had it happen, so I cannot say how long, but if you continue to try to use the PDA on the backup battery it won't be long (minutes) if it even lets you do that. The backup is there to bridge over battery changes and to act as a safety net if you run the main batteries totally flat. -does the backup battery recharge or does it have to be replaced? Replace. -with a fully charged unit how long can it be left off before data is lost? Depends on the machine. Most of us leave the thing in the charger overnight every night, so this issue doesn't come up. You could try an experiment for 1, 2, 3 days, looking each day at the battery remaining and work up an estimate. I would expect maybe a week or more. Remember, even "off" the machine is still drawing power to maintain the RAM memory.

WHAT DOES SENSE LOSS MEAN

RPM Sense loss means that the generator controller hasn't received a valid signal from the ignition coils for 3 seconds of attempting to start. Probably a dead or low battery or bad ignition coil. Replace the battery and try again. Call dealer if problem persist.

Could a short in the plug that goes into an ignition coil for cylinder number 4 or 6 cause a loss of power, a loss of pick up, and can cause a car to completely shut down?

Please charge your battery with a charger before you fry your charging system. It may need to be replaced. It may be too late for your charging system. When you drain the battery dead, there is still chemical energy left in the cells. If power draw is stopped, the battery will seem to charge itself and work again. In doing so, a part of the capacity is sacrificed forever. If the battery is drained empty more than a couple of times, it's time for a new battery.

To the car, a dead battery is an overload. Some vehicles are designed not to try to fully charge a dead battery. Most vehicles will burn the charging system up trying to do so. Same idea, if this happens much you will need a new alternator and maybe more parts.

I would definitely have the car serviced by a pro shop, with veteran mechanics. Discuss your concerns with the ignition and charging systems, and tell the tech about your power loss event. Symptoms such as this are better fixed before murphy's law kicks in and you are left stranded on the road somewhere. The repairs cost less before everything is destroyed as well.

How to retrieve lost data

I am sorry for your loss, but there is nothing you can do to retrieve the programs. But cheer up, you have no more figuring out to it, just retyping. And no, the calculator has nothing against you. It just ran out of fuel (batteries depleted). Calculator batteries are supposed to be changed or recharged.

Hi. Actually, on pocket pcs there's a backup battery onboard, but in your case maybe backup battery is dead. So you can have that changed or you can charge your PDA on regular basis. Hope this helps.

Ibook G4 14" 1.4mhz

On an Apple system, this is an indication that it thinks there is little or no battery left and goes to sleep to protect data loss. Your battery might be going bad (showing a full charge, but lasting for only a few minutes) or there may be a problem with your power supply.
