Hp iPAQ h1945 won't start
Hello and sorry for the delay.
the h1945 series is a very intresting pda. I have seen all sorts of problems relating this one. There are some things you may want to try. Based on that knoledge I may be able to find what's rong with your unit.
First, check if the back cover fits tight on the back of the unit. It's important because on some ipaq models, there is a small micro-contact that doesn't allow the unit to power on if the back cover isn't attached. I'm not sure if the 1945 has one, it's been 2 years since i've last phisically repaired one of these, but you may look for one yourself. It's a small contact near one side of the back opening, check to see if it can be pressed. If you don't have anything like this just ignore this tip.
Second, leave the pda connected to the charger for about 6 hours. Even if it doesn't do anything. Then try to start the bootloader by pressing the 2 outer keys near the D pad (simillar to the hard reset procedure) then, while keeping those pressed, press the power button and in the same time press the soft reset button with your stylus. You must do this with your charger connected to the pda. It may be difficult to achieve in the first try. Just try to do this a few times and if the pda doesn't respond even now, please post back. Furthermore, if you need more info about these 2 tips please reply.
