Question about HP iPAQ RX3115 Pocket PC

1 Answer

Battery draining So, I'm connected to USB. And when I go to turn it on, nothing. I need to plug it into the computer to get it to recharge. Funny part is, I bought one for my wife too, and hers does the same thing. What is up???? Why don't these stupid things just work. How do I get the battery to drain while hooked up to USB, which should be charging it like it does all the other devices I hook up to it! Thanks for any info,

Re: battery draining

Could your computer be using unpowered USB? Some machines and hubs have unpowered ports. Check the Right-click My Computer, Properties, Hardware, Device Manager, Universal Serial Bus Controllers, and find the listed hub which has the iPAQ connected to it. How much power is it drawing, and is the hub self-powered? (look at the power tab after double-clicking the hub) Also, is USB charging turned on? It's in the Power section of the Settings under the "USB Charging" tab.

My Kindle Fire will not start


If you last charged it with the computer USB port, try charging with the supplied AC adapter instead. If you last charged with the computer USB port, try charging with the AC adapter this time. This will help isolate a bad AC adapter / power cord or USB cable / USB port.

It is important to note that if you are charging your Kindle via USB port on a computer, when many computer enters "sleep mode" the USB power is shut off at this time too. Charging is effectively halted - even though still connected. You should only expect to charge while the computer is active or when using the AC adapter.

You can also purchase an aftermarket DC charger. These are small plugs that are inserted into your auto's port or cigar lighter. They provide 1 or 2 USB connectors to plug in a USB cable. These devices are suitable to supply / charge just about any devices that uses a computer's USB port to power / charge a device. They cost anywhere from $5 and up and look something like this:

How to turn on the phone spv m3100


there should be a turn on button hold down for 1-2 seconds at the top of the phone if nothing happens the battery may be dead i have an mda vario that if it is not turned on the battery won't charge its just the way they work not a fault.
I got it working by taking the battery out and cut off the small end of a normal usb lead i.e. big usb to small. strip the wires and there should be a red and black wire, posative and negative the red posative and the black negative.
attatch the red wire to the posative metal strip on your phone and the black to the negative strip on your phone, it should say on your phone by the battery or on the battery which side is posative and negative. turn on your computer and plug the usb lead in and then insert the phone battery making sure that none of the wires touch any of the other strips on your phone let your computer load and press the on button at the top of the phone for 2 secs and wait it should turn on and charge.
wait for 10 or so minutes making sure the phone is charging, then plug your charger for your phone in and at the same time remove the usb lead and wait for the battery to charge before taking the wires out of the phone.

I cant get my mda to turn on i hold down the power button for a while but it wont turn on i charged it for 3 days and it still wont work what should i do?


Mda Vario's don't charge when turned off, heres what you do.
cut wire off a usb lead the small end strip the red and black wires, put the red wire onto the posative connection where the battery is it tells you what side is posative and negative on the battery, use black with negative and red with posative making sure that no wires touch the other metal strips in the phone, replace battery plug usb into computer and start up the mda and wait for it to boot. once turned on leave to charge as it will charge through the wires connected to the battery, after 10 to 15 minutes plug in the actuall charger and try to remove usb wires without taking battery out. if that is not possable it is ok as the battery should have enough power to start up once it starts leave to charge and always keep some charge in the phone.

Just wondering how to connect it to a computer?


Hello,

The Samsung SCH-i730 doesn't have a USB port, but it has a different port that underneath the phone itself. You need to use an adapter so that you could connect it to the computer. Look for the adapter SCH-i730 Lil Sync USB connector.

There could be a possibility that the battery is not working correctly. To isolate this, try to use another battery to see if you will get the same problem.

NOTE: To take care of the battery, never charge it if it's not running out of charge. Never unplug the charging battery if it's not fully charged.

USB Connection


Hi,
I fixed my problem of my HTC touch not Syncing with my phone thru the USB cable.
Go to
Start, Settings, System, Power, Advanced and select/enable the option that says "When device is turned on, do not charge the battery when connected to the PC."
If it still does not work at first then disconnect the USB from your PC/device, wait a few seconds and then plug it back in.
You'll suddenly see your phone and your PC syncing.
Hallelujah!

Motorola A1200 Problem


Easy step by step solution!

Hey guys had the same, Try this solution before buying a new battery/charging cable (it might not be the problem):

I did these steps after playing around with it for awhile and am at the stage where my phone turns on fully and says "Battery Charging" when plugged into the charger. It is now charging normally again... Finally! (I had the flashing moto logo too when charger plugged in) I believe this problem occurs because the battery is completely drained and is unable to turn on to charge bcuz the phone needs to be on to be charged, happened to me because i left it in a jacket pocket and forgot about it for weeks. Anyways...

1. You need a USB data cable for it, it should have come with the phone, if not than any USB data cable that fits the phone's charging slot should work (charge cable for the ps3 controller will work or maybe a cable from a digital camera with the same end)

2. Connect the phone to your computer via the USB cable and a USB port that works. Make sure it's plugged in and leave it (even if nothing happens and the screen on the phone is still blank). Although the screen is black, the phone is still charging via your computer (it's just too low on battery to produce the light on the display screen to load up your phone).

3. This might take anywhere between 15 and 45 minutes so be patient and leave it plugged in, beats buying a battery of charger with your money for something that can be solved for free.

4. At some point your computer will make the usual processing noises signalling that it is finally recognizing the phone as a usb device and shortly after your ming's screen will turn on stating that the battery is charging. Success! One of two things will happen, if you have previously installed the ming's drivers to your pc it will just recognize the phone. If you are like me and do not have the drivers installed, you may choose to do so via the cd that came with the phone or just not do it at all.

5. If you want to just charge it via the computer then congrats, your job is done, just leave it plugged in and wait until it is fully charged. If you wish to switch to your regular outlet charger please proceed to step 6.

6. At this point drivers installed or not, either safely remove device from the computer or just unplugg it. Now return your phone to your usual outlet charger making sure its connected. When plugged in you'll notice the moto logo appear (no longer flashing). After about 5 seconds that logo will disappear. At this time flip open the phone. The usual turn on sequence will play out and it will now load up with the battery charging screen similar to the screen from when it was plugged into the computer. Congratulations your phone should be back to normal now.

NOTE: This charge will take longer than your normal charging time but that's just for this time since your battery is super low it will be back to normal after that. Also if this did not work for your phone then now is the time to see if the charger/phone/battery is the problem.

So I hope this helps you out and eases your state of panic. I hope I saved you guys some money with this solution and that your mings are up and running again. I know i was pretty content when the problem was fixed. Please reply with any comments, questions or concerns you may have. Enjoy your once again working mings.

Drained batteries, not powering up, next step?


For me I prefer charging the iPAQ using the usual cable, not the USB as I had some troubles with that It makes the battery drain faster. So Use a usual charging transformer.

IPAQ 3700 series


Most iPaqs use a small AC Adapter This model will still need an AC Adapter, because it does not draw any current from USB to charge.
