SOURCE: HX4700 will not power up

I have repaired many of the Hx4700s that appear to be dead by shorting across the "battery locked" switch. It is located on the lower right corner of the board when viewed from the back with the cover off. The switch just shorts to ground when the battery is locked in place. By flowing a small bit of solder over the two connections on the back of the switch, the iPAQ will return to life and there is no ill effect of bypassing this switch. In my opinion the switch is to fragile and poorly placed.

SOURCE: Ipaq 4155 wont turn on, dont charge, dont anything, is totally death

Hello,

I had some similar experiences with these ipaq's when I was working in a specialised service center. I'll try to give some help or tips through the internet, altrough if i could have seen or diagnosticate these pda's myself it would have been more easier. First of all these problems have 2 main causes. Most of the pda's comply with one of them, it is very rare that a pda will develop this problem by having both causes.
The first cause is the hardware one. A component called the main voltage convertor is broken. It's a small chip that uses the voltage given by the main battery to convert it's value to various tensions required by some of the components on the pda's main board. If some sub-parts of this chip fails to work, the result will appear as the problem you face, In this case there isn't much to do. Most service centers will replace the whole mainboard because that particular chip is very hard to find as a replacement and difficult to desolder from the board.
The second cause could be a major firmware / ROM memory corruption. These things can happen out from nowhere. In my time working for service centers I've tried to isolate a pattern for this problem but without much succes. However it seems that most of these problem tend to appear durring charging cicles due to power spikes or drops on the main AC voltage supplied to the charger. This is only a supposition, I'm not sure yet on this cause. What to do here? Well this problems are fixable but first of all you must be sure that this is a software problem, not a hardware one. So let's diagnosticate some things.
Try to charge the pda. Ignore any lights or beeps or whatever your pda is showing on the screen. As long as the charger is connected the charging process is based on the most primary charging circuits on the pda's motherboard. If the pda is not charging or cannot hold any charge (when you unplug it the screen fades away or it simply doesn't do anything else) maybe that circuit is broken (this is a a sign of serious hardware problems ) or maybe the battery is to old/weak. Batteries don't die out of nowhere, if you remember your pda to work and have some 2-3 hours of standby time it's imposible that now, suddently the battery has drained out so much that even if charged it can't hold out at least 30 min.
So we will assume that you charged the pda for at least 2-3 hours and you see some sign that the battery is working. The next step is crucial. TRY TO PUT THE PDA IN BOOTLOADER MODE. You will achieve this by pressing (and keep them pressed!) the following buttons : power, the far left and right buttons near the control pad (joystick or whatever some people call it) and reset button. You may need another person to help you press these buttons. the order should be the following (first power, then the 2 keys, then reset button for as long as it takes to enter bootloader mode). YOU SHOULD SEE A WHITE SCREEN WITH THE HP LOGO.

If your pda fails to do that, there is nothing more you can do to restore it in a DIY fashion. Probably the bootloader is corrupted or you have a hardware fault. Only a specialised HP service center can help you now. In most cases this will end up with a motherboard replacement.
If your pda does that, then there is a chance to fix it. We will need to probe the bootloader for direct data acces. This is needed for having the ROM memory (and operating system) rewritten. A small program called Mtty will be required to access the bootloader via an usb link.

Please make this tests first and then reply with your results. If anyone of you is in situation #2 there may be a chance.

I Also Had The Same Problem. Now I Fixed It. Go To Power In Settings. Click On The Advanced Tab. Uncheck The Box Which Says "Turn Off The Device If Not Used For" Box. This Will Solve The Problem. It Solved Mine. Thereafter Once, My Backlight Did Not Switch On. Fix This By Going Into Backlight Settings And Uncheck The Box Which Says "Turn Off The Backlight If Not Used For" Box. This Will Solve It. Then Soft Reset The Device To Change Settings. To Soft Reset, Find A Small Hole In The Left Hand Side Of The Device. Put Your Stylus In And PRESS ONLY ONCE. If You Keep It Pressed, Your Device Will Hard Reset. Don't Do That. Just Press ONCE.

HP ipaq 6315 No power


Hello i'd be happy to help :-). Since you said that you bought a new battery and it still didn't work. I am guessing that you might have charged you Ipaq by pulling it into a regular wall outlet . This is bad because that outlet could send to much electricity into the Ipaq and can kill it. That might be the problem why your Ipaq is not working... I would recommend for you to call HP and see if you can return your Ipaq to them and see if they can send you a new one.

Will not start up after recharging the battery


Hello :-) I think that your battery is causing the problem. You might have charged you ipaq to many times with a cheap battery and the battery might be completely dead. Or the battery might just be defective.

Battery issue


I THINK IT TO BE THE PROBLEM OF BATTERY. COZ IF U LEAVE UR BATTERY FOR A LONG TIME WITHOUT CHARGING IT IN REGULAR INTERVALS, THE BATTERY NORMALLY GOES OUT AND DIES. IT MAY BE UR PROBLEM. SO JUST REPLACE A NEW BATTERY AND CHARGE IT AT LEAST FOR 8 HOURS FOR THE FIRST TIME AND THEN ON THE IPAQ. IT MIGHT BRING A SMILE ON UR FACE.

IF THIS SOLUTION SEEMS HELPFUL DONT FORGET RATING IT.

Just "turned off"....


Was it charging over the weekend? If not, try to recharge the device again... Those devices would on occasion drain the batter overnight -- didn't happen all the time and was apparently caused by unusual software/applications combinations... The battery could be going bad again as well.

My H5450 won't charge!


When you charge up your iPaq, do you use the cradle, or do you use the AC-adapter with the little iPaq power converter that came with the iPaq? Try both, and see if it charges up your pda. Try and borrow an iPaq car-charger and see if it charges up that way (the ones that do not need the iPaq power converter). If you are lucky enough to power up the iPaq even for 2 minutes, enable USB fast charging in the SETTING -> BATTERY. Your USB-data-cable or cradle will then be able to charge it up that way...
