AC Power Adaptor Not Reconized

  Hello everyone. I have a Inspiron 8500 3 months old when the screen of unknown power adapter. You hit F1 to continue or F2 to enter setup. In setup the charger was an unknown type. The batteries would not charge and the PC would only work with the cord plugged in. It would only run at 1.2 instead of 2.6. I called Dell and they replaced the adapter. This did not help. So a tech came to my house and replaced the motherboard. Thank god I paid for the total care package. Also they said he would be over in two days and it was 6 days before the tech came. Well he replaced the motherboard and processor. Updated the bios. It worked again. I was so glad. Now 2 months later and guess what. Adapter unknown. Not every boot just now and then. The battery is still charging and running at 2.6. Called Dell and guess what, we will send you a power adapter. So it begins again. I told the tech last time they ended up replacing the mother board at the end. Well of course he had to follow his guidelines of problem resolution. The last tech was aware of this power problem. She stated I'm almost sure it is the mother board but we must try the power adapter first. Dell knows of this problem and needs to address it. Something is wrong with the design. This is stupid, second motherboard coming I can see. The adapter works fine in my other laptop. I have the extended warranty so this may cost Dell allot of parts in the long run.

OK now I need a mother board if they can ever connect me. And it is happening on every boot now. Talked with a tech and they will replace my motherboard for the second time. The tech tried to transfer me to facilitate this yet I got disconnected two times. Will call again and wait on hold again. Last time this happened it took 5 tries before I got connected with someone to fix it. Well here I go again. And I told my mother in law to buy a Dell.

OK I got thru to tech finally. I've been on the phone for the last hour. He told me my motherboard and power adaptor will be replaced. He told me to make sure the tech uses the new power adaptor. He said there have been problems when they use the old or new one they just sent me. This is a strange problem if you have to make sure the new adaptor is used. He said they have had this problem reappear when the old power adaptor is used, usually in 3 to 6 months. OK I'll bite. Just sounds strange. Always thought parts were parts.

Now 5 days waiting for next business day repair, the tech arrived and replaced the mother board and power adaptor. Now we shall see what happens. Hope they have fixed this motherboard problem. New Laptop 4 months old and it needs a new motherboard and now 2 months later it needs another motherboard. Hey maybe third times a charm.
