Hi. I own a Dell Inspiron 1545 laptop, everything about it has been great right up until about a month ago. I started receiving the following message when plugging in my laptop: "The AC power adapter type cannot be determined. Your system will operate slower and the battery will not charge. Please connect a Dell 65W AC adapter or higher for best system operation." For a while I was able to just unplug and replug it a few times to get it working again. Now it refuses to recognize the adapter. I am using the Dell power adapter that came with my laptop. I called Dell about the issue and they want me to send them my laptop to replace the motherboard. I use my laptop for school and work, I can't be without it for however long it will take them to receive it, fix it, and return it. I have done a lot of googling and have failed to find a fix other than one that involves disassembling hardware (which I'm not comfortable doing with a laptop). Shouldn't a BIOS mod allow this adapter check to be circumvented? (I have the latest BIOS update - A13) Any advice or guidance would be greatly appreciated. Thank you.
