I'm looking for help in solving a problem with my Dad's i-opener. Symptoms:
- after some minutes of normal operation the system becomes unresponsive. When you click on a control or icon no action occurs.
- after some repeated clicking on things the screen goes blank except for a small box in the left-hand corner of the screen.
- if he unplugs the power and waits 30 min or so then it will start up normally again.
- earthlink tech support says this is a hardware problem, probably the video card.

I'm looking for suggestions. Mt brother & I both know our way around PC's but the whole idea of getting our 77-year-old father the i-opener instead of a windows machine is that we would not have to be the 24-hour tech support crew...

Can someone on the board steer us toward a fix ?

Check to see if the heatsink is making good contact with the processor. If the processory overheads the screen freezes in the manner you describe. Also, have you changed the memory stick? Some i-openers (V5's) have a problem with memory upgrades. A little more info would hopefully lead us to a quicker solution.

thanks, this box is vigin, no one's changed the memory stick or even opened the case.

Did the i-opener work ok before this problem developed?

This happens to my io when it sits without using it for a about 10 minutes. The only way I have found to wake it up is to tap one of the mouse buttons, I think the left one. No keystrokes seem to work. It takes about 5 seconds or so to "wake up".

It sounds like your already trying to click the mouse buttons, so I would go with the overheating theory. Maybe set it up with a fan blowing on the back of it and see if the problem still develops. If it doesn't then you know it is heat related.

One other suggestion, the keyboard connector is pretty cheap and flimsy. Maybe a connection is losing contact as the machine heats up. That would send the machine into "sleep mode".

My dad's IO has worked well for about a year, just starting exhibiting the problem recently. He's tried disconnecting/reconnecting all cables, etc, and from what he tells me it does not seem like a connector problem (hard to tell without some hands-on,though). I don't think the unit is going to sleep -- what the describes is that after a 1/2 hour powered-down, unplugged rest, the IO will boot and he can get a few minutes use out of it before it checks out -- first by ceasing to respond to mouse clicks and then by a greyed-out screen.

I've been looking over the many posts in the technical areas regarding adding a small 5-v fan. This is kind of looking like a likely line of action. Regarding the onset of the problem, though: it is realistic that the heat-conductive foam between the CPU and the heatsink would degrade after a year, and that onset of symptoms would be fairly sudden ? The sudden onset does make we wonder if the overheating scenario is it ....

I had a simular problem with my V4b that I used with the netplince service. But mine would only show that behavior after 3 or 4 hours of serious surfing. It is a heat related problem. The processor gets too hot and shuts down. Only after turning it off and letting it cool for a couple of hours would it operate normally again. Either your processor is failing or the heatsink has worked itself loose. The only way to find out for sure is to open it up. I never had that problem again once I had switched to a Tennmax fan. That heatsink wasn't the best design possible for the i-opener.

Looks like another kind of problem ....

My brother the EE installed the lasagna fan last weekend. The operation was a success but the patient shows no improvement! He says the CPU is plenty cool now, but unit is still flaking out. He was able to glean a few more details on symptoms:
- even when it seems to be unresponsive to mouse clicks the system will sometimes respond to some of the function keys;
- sometimes he can navigate to and play back audio although he can't get to the mail or web browser functions;
- near as he can tell the unit is able to connect via the modem;
- there is a random element in the appearance of the symptoms.

He tried reseating cables, connectors, etc. with no good result. Any thoughts ?

thanks,

The only other reason that I can think of that causes those problems is that a program that runs in the background takes over most of the processor use and slows down the operating system to the point that it doesn't respond. When the described behavior appears, try turning the iopener off. When you do that, do you get a message from the computer that says something like "XXX programs not responding. Do you want to cancel, wait a few minutes or do nothing"? If that is the case, try turning off all of the background programs one by one, to see which one is causing the problem. You can do that using the program "msconfig".

I agree with Ragnar that this is beginning to sound like the culprit is a lack of system resources. I'm afraid I don't know too much about QNX and the virgin I-Opener software, though. Ragnar's fix only works on Windows-converted machines. Hardware-wise, I'd get your brother to check the memory stick to see that the connection is both clean and well seated. I've seen plenty of machines over the years where repeated hot/cold cycles eventually caused memory to pop completely out of the socket. This may not be your problem, but it's worth double checking.

Thanks, guys. Since the IO is running the original QNX system & netpliance BIOS programs we really have no control of background processes and resource usage. Since the occurrance of symptoms is semi-random I do not suspect a firmware problem such as curruption of BIOS. The memory does seem likely ... I will see if bro reseated the memory stick.

Dad keeps trying and the unit worked enough last night that he could send me an email. I had offered to set him up with an old 486 boat anchor running Win95 -- he'd rather have another IOpener if we can't fix this one up ! He is they guy that this 'appliance' idea was invented for. Maybe we'll hit ebay and see what we can come up with there. At least we'd have two of everything to cobble together a system from.

There is a boatload of used Iopeners for sale on eBay right now. Going prices are less than 100 dollars. Just make sure you do your homework and check out the feedback of the seller.
