Query: Out of Service Life - No Parts Available

I bought an H5550 in April this year (2008), supposedly with 12 months warranty. A week ago it failed to turn on. I borrowed a fully charged battery, tried hard reset. Tried holding power button on for one minute as advised by HP. No go. Commenced warranty claim to be told, "this product is outside its service life. There are no more parts available for it".Before you buy, search the web for customer reviews. You'll find its given HEAPS of trouble. It appears to have been the lemon of the range, often just dying like mine did. If you try to get it fixed you'll probably be told by HP - like I was - that they can't repair it.
