Hi again,

Well, after purchasing a new battery at the suggestion of the Dell help desk, it is now totally discharged too! Another tech advised me that since the BIOS is not recognizing my power adapter at startup I need a new mother board!  yah right.

I don't really use this thing as a laptop.  When I showed it to my co-workers it was dubbed a moble computer, not a laptop.  Anyway, I always have it plugged into power and it functions just fine that way.  But lose power and CRASH!  So, this is my first and last laptop.

Thanks for listening,

Rich

Guys this is a manufacturing defect with the XPS 1730 power adapters as well as many other adapters for other Dell models.

Does it say in your BIOS under the AC Adaptor: Unknown Device Installed ?

If so then the PCID wire in the power cord that communicates with the laptop has torn because its so tiny, or the ID chip in the power adapter is dead. Or even worse the ID chip on the motherboard that communicates with the power adapter is dead, in which case you will need a new motherboard and or new power brick if you want full power back. Yeah took me almost a year to find why my 1730 is running so slow. When the BIOS cannot determine the ac adapter connected its performance is reduced from its stock speed of the CPU, and if you have a x7900 or x9000 CPU overclocking will not work.

Motherboard getting ready to bug out on you. Mine did this for the longest time. I replaced battery and power brick. Finally I said the *** with it at least its working on plug in power. Then one day I left my computer on for an hour came back and it was off. I tried turning it back on and notta. Changed batteries and power brick, nothing. Motherboard had to be replaced..
