Unit worked well this morning - docked all weekend. Colleague couldn't power his 4700 up. Offering help, I took battery from mine and put it into his. Didn't work. Worse, I put his battery into mine. Didn't work - now they're both dead. Both batteries have full charge. Soft resets (Stylus in the end) didn't work, Hard resets - (hold two keys + stylus in the end) didn't work. Neither unit powered up when docked (tried three docking stations). Neither unit powered up when docking station bypassed and plugged direct to A/C for charging. No charging lights, nothing. Dead... Lastly, I tried removing a media card and re-inserting it (which usually forces powering on) - nothing.
Any ideas?
I have the same problem. While it was online upgrading software it powered off by itself and now even after hard reboot and battery locked in place it will not turn on. I also tried reinserting the SD card and still nothing.

I have a very similar problem. Was connecting to wi fi when unit turned off. I turned it back on but is cut off again shortly another attmept to turn it on resulted in the blue Hp iPaq screen coming on but nothing further. I cannot turn it off, get past this page. I disconnected battery for short time. same result. Disconnect several minutes. Sames result. Plugged into ac charger, usb port on laptop. same result. I don't know if these problems are related or not, but the battery locks are secure, battery charged.I have a very similar problem. Was connecting to wi fi when unit turned off.

the battery "lock" tabs were the solution for me. Acutally figured out with help of HP support (via IM)...wi-fi search f/b shutdown isn't an issue. I've heard that the PDA equivalent of a CMOS battery is probably at fault. They run out and can only be replaced at HP headquarters.the battery "lock" tabs were the solution for me.

My unit is completely dead too! I have tried all f the items discussed and no luck. It is completely dead. Last week it acted funny a few times. Quite common to the discriptions earlier where it would not turn off or would turn on with no back lighting.
Its ironic that so many are failing at this exact time frame.
Discription: No lights, w/ or w/o charger. Chk'd battery lock switch. OK
Left battery out 40 minutes still nothing. Can't sync. Dead....My unit is completely dead too! I have tried all f the items discussed and no luck. It is completely dead.

How to correct iPAQ 5450, 5455, 5550, 5555 battery charging problems / dead unit syndrome.
The iPAQ 54xx or 55xx will not power on if the batteries charge is lower than 3.2 Volts, if your battery charge falls below the 3.2 volts level your unit will not turn on, you need to plug the iPAQ into a cradle or AC charge adaptor. Note the charging light on the iPAQ will not flash at all (normally flashes orange) until the battery charge has reached a minimum charge level of 3.2 volts. You then need to perform a normal reset, then the unit should switch on normally.
HP Procedure is as follows:
To charge and reset the iPAQ Pocket PC h5400:
i) Connect the iPAQ Pocket PC h5400 to an A/C power supply. ii) Charge the battery to the minimum level of 3.2 Volts. This will take 5 to 30 minutes depending on the current charge level. iii) Perform a normal reset. iv) Power on the iPAQ Pocket PC h5400
It is recommended that you keep the iPAQ Pocket PC connected to the Universal Cradle or Cable when it is not in use.
The AC charging lead adaptor looks identical to the adaptors used for other devices. The internal wiring in these adaptors is not consistent. I know from bitter experience that using an XDA2 adaptor on a hx4700 will burn out the printed circuits on the motherboard.
When you insert the battery inthe hx4700, the battery lock must be in the locked position.
This lock closes a microswitch inside the PDA. If the microswitch is not closed, then the PDA will not do anything, including power-up, charge the battery etc.
Unfortunately, the microswitch is very tiny and (in my opinion) quite feeble - definitely not up to the job, especially if you remove and replace your battery frequently (many people carry spare batteries). On my hx4700, this switch failed. At the time, I just assumed the whole thing was dead and bought another off ebay. The same thing happened with the second one. I guess the switch can be replaced (at some ridiculous price). I read somewhere about somebody who permanently shorted out the connection by soldering a wire across the switch terminals and it had no ill effects. I wouldn't necessarily recommend it though.
Having the same issue myself but when I plug it into the wall with the AC adapter it powers up but the date goes back to March 2005. Just got the device via e-bay waiting to hear from vendor.
I took the battery out and left it out for about 30secs and still no power. Both tabs are in the lock position, and still nothing as of yet. I don't understand, could it be the battery? The battery shows a charge of 98% this morning.I took the battery out and left it out for about 30secs and still no power. Both tabs are in the lock position, and still nothing as of yet.

Make sure that the battery lock is pushed back to the correct position. i.e towards the reset button. If it is not locked the machine will not power up.

Sometimes the connectors on the dock get bent. Look to see if anything looks out of place. Unplugging the unit is a reset left unlugged for a couple of hours. If you need repairs try esupport.sony.com. Hope this helps.
My remote worked perfectly until I changed the battery. The original battery was CL 2032 and I replaced it with DL 2032. After replacing the battery, only the volume control works. The off button will only fade the sound while the button is depressed. Release the button, and the volume returns to the original level and the unit remains On.
None of the other buttons work.
If you've found a solution, please post it here.
I actually had the same issue with mine.. it was 6 years old and just stopped finding the docking station. Also wouldnt take a charge. So I just eliminated the docking station. The stations power cord will charge the unit. Hope this helps.
My Z760 does the same thing. When that happens I run the battery completely down by taking pictures until it shuts down. Then when I put it on the dock it charges properly. Don't leave your camera on the dock all the time and don't try to always keep the battery fully charged--instead it will develop memory and think it needs to be fully charged to run and will give you a low battery signal earlier than it should. Wait until you actually get a low battery signal before charging and it should help, but mine will still give me the red light sometimes. Then I run the battery out like I said before. I hope this information helps. :-)
I posted on July 16 with this flashing problem and played around and got mine working again.
Originally I would charge through the docking port. What I did was pull the charged rechargable batteries out of the camera and took the charging cable from the docking station and pluged it directly into the port on the side of the camera. The camera started working again. Then while the charging cable was pluged into the camera, I reinstalled the rechargable batteries. After installing the batteries I unpluged the charging cable and the camera still works. I have shot and downloaded from the camera pictures with no more problems. Use the docking for downloading pictures and the side port on the camera for recharging the batteries.
I do not know if this has anything to do with the original problem but I did not have any problems with this camera until I placed it on the docking station with non-rechargible batteries.
Hope this helps.
What you are describing may very well be a result of the battery going bad. The internal battery in your GPS receiver does have a limited lifespan. It is normal for the amount of operating time between charges to gradually decrease until eventually the battery pack does fail.
Unfortunately the battery does not appear to be replaceable by the user. To get the battery pack replaced you can contact Garmin directly. Their website is http://www.garmin.com.
Had the same problem, worked just to rotate the power cable into the back of the sound dock. Printing on the plug goes on top. It worked like a gem, after trying new batteries, resetting, etc...it was just an incorrectly placed plug!! Thanks for the help!! Listening now to some great music!
If your Zen V wont respond to anything, try this, plug it in to the computer, hold the power switch in the on position, THEN trigger the reset button, worked like a charm for mine, I had thought it a lost cause."
