sounds like your motherboard malfunctioned. the board was probably starting to go out. thats why it would see the hdd then not.

you sound like youre familiar with computers. you may want to invest in diagnostic cards to troubleshoot problems like this. theyre fairly inexpensive on ebay. basically you insert the card into pci slot and it displays an error code. then you look up the code in a book. works like the obd2 reader for your car.

good luck

If you have a desktop computer but listing it as a laptop with a problem you will get the wrong information back to repair the unit so you need to take this out and resubmit it as the proper unit before anyone can give you the correct information!

Most of these HK receivers have a 3.6v rechargable battery on the front panel board. If the battery dies, you lose memory when it is turned off/unplugged/power failure. The battery is soldered on the board. Not replaceable by the user unless you are a tech. It should keep memory if left in standby.

Data missing - Ipaq model HP5555 - did not do hard reset


Hello,

I'm sorry but the HP Ipaq 55xx series store data on a volatile ram based memory. Unlike a nand flash (like usb sticks, memory cards etc) this memory will hold data only as long as it's powered on. If your main battery gets empty you should still be able to retain your files for some 10-20hrs with the backup battery (if it's ok itself and not depleted). After this time the power to the ram memory is cut off and all data is lost.
The problem you face is somewhat related to that backup battery, as it appears it's unable to do it's job and maintain the power to the ram memory at least some 10 hrs. You should have that battery replaced.

There is no way to recover the data from the ram memory as it is stored as an electric charge over some memory cells in the ram chips. When there is no power, these charges dissipate and the pattern is lost.

I'm sorry for having to give the bad news.
Bogdan

Dell 1505 Inspiron... Dead?


Motherboard failure, you can buy one on Ebay for about $100.
To confirm, remove RAM, Drives, battery and wireless cards, see if the LED indications change. If no change, then the MB is confirmed bad. If they change, add 1 RAM module back, see if the system will post enough to get into BIOS. If it does, add other RAM module. Keep adding items, (Wireless, battery, CD Drive, then HDD) and ID the one causing the failure.

Lost data


Sorry to say your data was stored in ram memory and when the power is cut the data is gone forever, there is no way to restore your data from ram memory ones it no longer has any power.

now that it has power again the data will stay in there. So I recommend you use a memory card to store your data, as a harddrive so you wont loose your files. Remember to perform backups also so the device can be restored, incase another power failure.

PROGRAMMING


You have to get into your database programing "Feat, #, * " Says enter password, Default is 00000000. Enter into "Staion" then where it says "Show sta" enter 11,12 13 etc. "show" scrole to "CO Line Ring Assignment" Enter "Both" on each station you want to ring. Station #10 is the only default station that will ring without reprogaming the other ones to ring along with it. Hope this helps.

Loss of data when battery goes dead?


-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.
