Completely dead iPad, not in itunes

Got an iPad in for a client, she smashed the digitizer a while ago and muddled on for a bit, but she said it wasnt coming on all the time and she was having to do hard resets to switch it on until eventually it just stopped coming on.

I have it today and have tried hard resets, DFU mode, itunes doesn't see it. It shows up as an unknown device in device manager in win7, but nothing in xp. Nothing flashes on screen, nothing happens at all.

I opened it and took the logic board connectors off the batteries, left it off for half an hour to see if that would do anything & nope, nothing.

I cannot think of anything else to try at all. I dont really want to start ordering random parts at this stage, but I wondered if it could be the power button, but that wouldnt affect it showing up in itunes etc.

Any ideas will be greatly appreciated!

Could it be the battery perhaps? Can someone help me test that with a multimeter at all?

OK, i just got the very low battery image come up, and now it wont come back. It was when it was plugged in to the pc .... so screen, backlight and power button are ok.

par

It also appeared as an apple mobile device (dfu mode) for a couple of seconds in device manager. I am starting to think battery ...

After replacing the dock connector and removing the battery and still not getting anything, I think it must be the logic board and the client was not willing to pay for a new one. So case closed, albeit unsatisfactorily.

if the battery gives you problems, disconnect battery and give ipad power with dock connector.

if ipad still doesn't boot, check dock connector

What would be the best way to disconnect the battery? Just remove it by pulling it off the adhesive, then reassemble without it?

Ok, took the battery out and reassembled, remembering, at the last minute, to put something under the contacts on the logic board to stop them coming into contact with the case. Put it back together and still nothing. Try a new dock connector you think? They are cheap enough.

yes that is the first thing i would do next. check if the old one is properly connected, if so try a new one.

have a nice repair..

Ok, weird thing just happened. I left it on charge plugged into a pc over night, it was about 30% full when i got up, it worked fine, till i plugged it into a plug power supply and it instantly went off and wont come back on. Ordered a new dock connector, lets see how that goes!

par

OK, got the new dock connector in it doesn't seem to have made any difference. I tested the terminals on the battery and it is outputting at 3.48v. Is there anything else it could be, or is it looking like looking like shot logic board?

Hi,

I have the same problem. There is no display but if you connect to PC, iTune detects it and reports that the iPad is in recover mode. Reinstall / upgrade iOS will not help.

But If the battery charged to 100% (you can ipad connected to the charger in DFU mode for more than 10 hours) and when the charger supplies the current, the iPad2 wont go to DFU mode. If the iPad is not connected to the charger, then if you leave the screen off for 10 minutes or more it goes to DFU mode and wont come up at all. The no. of reset trials (Power+Home button) to rbing up the display and boot are less if the battery power is higher than 90%. I am thinking this is a battery problem. Has anyone seen this issue?

When iTunes can't recognize your device, this is the most helpful tool to fix it. Free and safe iOS reboot tool: Help you reboot iPad to normal state with one click. Free download it if needed.

But what if the computer itself is not finding the iPad?
