I have a PQH307, I have had it for 2 years no problem. I went to plug it in today and the casuntion light came on and it not go off. What would can I do? Thanks Sherran

it is very possible that you got a bad plug wire check and make sure the plug wire is seating right and staying in place

Just in case, leave it plugged in for another 60 minutes, its quite possible it went into the defrost cycle, in which case no motors will run. If it continues to remain silent, re post your problem.

What kind of shape is your 2 year old battery in?

time for new one, they are made to brake now days:(

I think you have more than one problem there. Take it to a local PC repair shop and have them check it out. Five years is a good age for a computer though so you may want to think about buying a new one. Best of the Irish Luck to yer.

your srs light is indicating a bad connection. Disconnect battery and wait five minutes, then plug and unplug the seat belt wires going to the end that you plug your belt into, This is just one part of the srs, but I have had many that it turned out to be abad connection there, Also if you had a scanner you could find exactly what the trouble was. Generally the code will indicate what is defective. Without a code it's a guessing game.

Hmm perhaps the USB Cable has dust in it. Have you tried blowing into the ends to clear any dust?

This isn't a permanent solution, but it has worked for me. The first time I found out about this solution was when the status light went out on my Tatung. I just left it unplugged and didn't plugged it back in for about a month and a half just to see what it would do. When the status light came back on, I knew if it ever did it again, I could try the same thing. Well, a week ago last Sunday, the status light went out again, so I just kept track of when it went out and when I plugged the power cord back in to see if the status light would come back on. Today when I plugged the power cord in, the status light came back on. That was 9 days. I don't know if it could be less than that because the last time I plugged it back in to see if the status light would come on was around last Friday. So it might have worked sooner. Anyway, this seems to work for me. I don't know what is causing it to lose power in the first place, but at least I know what to do.
