Question about HP iPAQ RX3715 Pocket PC
Hp ipaq turns on and off
I can only especulate on all the possible reasons, so let go one by one throuh them and their possible solutions:
1. The RX3000 Ipaq family has a known mechanical issue on the switch that senses when the back cover lid is properly closed.
When the switch is nor properly depressed, the PDA won't charge the battery if plugged on the cradle or to the USB sync cable, or won't turn on.
Remove the back cover lid and the battery, put them back again. Check the cover lid is placed flush and that there is not any gap between the cover and the PDA body.
Try again in power it on and/or charge the battery, confirming the orange LED light is turning on.
2. False contact on such back switch.
You need to find exactly where is located the switch that senses the battery cover lid.
It's located at the right/bottom side thru the battery bay. Check that there is not dirty or dust accumulated, causing that is sticky such area, which prevents such switch to work properly.
If you find nothing obvious, you can use small pieces of transparent tape (or masking tape) and put them on the internal side of the cover lid that is in contact with the switch (you have to locate first such area), put the battery and coverd lid again, and try to power it on. You can add a 2nd or 3rd layer of tape to depress such switch.
3. Broken cover lid. Check that is not broken in any part or corne rof it. If it's so, then replace it.
4. Defective switch.
Unfortunately is necessary to open the PDA and check with a continuity (or ohm meter) the performance of such swicth, which is easy but usually a technician does it.
You have the option of send it to be repaired, or try it yourself, which will require to buy a switch part, or pulled it from a PDA with possible working switch or the whole mainboard (or the mainboard alone) and swap the parts. It requires a minimum of technical skills to do it.
