I have an old Inspiron 8200 that has a strange problem. Im hoping someone out there might still be interested or remember any common problems with this ol crapper. It tells me when i boot up with the ac adapter connected that there is a 70 watt ac adapter installed and that i need to have a 90 watt adapter installed or it wont run at full speed. Sure enough it wont get above 1.2Ghz and it has a 1.7Ghz P4-M in it. I just bought a new ac adapter off of ebay and it still does the same thing. I have read that there is an dc power board in this thing that sometimes goes bad. Its $40 and i dont want to replace it if it isnt bad. Has anyone heard of this problem. When i disconnect the ac adapter it goes right up to 1.7 like it should, but it takes forever to charge the battery back up to 100%. I do like this laptop and would really like to get it back up to speed. Thanks for your input!!
