Question about HP iPAQ HX4700 Pocket PC
My HX4700 will not power up. It will also not charge when the unit is on the cradle. When I did a warm and cold reset it would come up to to HP screen but would go no further. I have 3 cradles and tried the machine in every one. The unit does not blink charge when it is put on the cradle nor will not power on. I bought a new battery and does the same thing. I have tried checking the battery clips to make sure they are tight. I have a separate charger for the bateries so I know the battery is fully charged. What could it be? Thanks
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.

May be obvouse, but have you confirmed that the batery is locked into position. my prob is that the switch where that batter lock slider pushes into pooped out, and i need to replace. ugh.

Hi I'm a pc repair technician, and my ipaq hx4700 has gone exactly the same way. I've been looking round for some kind of technical manual to see if there is any history of internal components going down through heavy use or even manual abuse. Mine stopped after I knocked it whilst working on something. Normally if I see similar symptoms on a pc I'd be looking at internal component failure, more often than not the motherboard itself. I worked on that theory and have looked at prices for an ipaq motherboard. In all honesty the costs for the part and replacement are more than buying a new pda. Sorry for the bad news, but thats the only option I've found all the best
