I have a very annoying problem with a friend of mine's Inspiron 8200. Cant seem to get any info from dell's website, so im hoping that you guys can help me. First when it boots, it says that th 70W power supply present, running in battery optimized mode. He has the new 90W adapter that dell sent him as a warranty thing. Also i have turned set all the speedstep functions at max performance, but windows always reads it at 834 Mhz. It has the 1.7 P4-M processor. I know that the power management can cause the processor to slow down. Is it possible that the power problem is causing the problem? I also set the windows power mangement to always on just to be sure, but no change. Also it gives the battery optimized mode even with a full battery. I checked, its the 4460 mah like is recommended. I dont know what to do, im at my wits end. This thing used to kick ***, but now its kinda a slug :? .
Hello,
I have the very same problem. I change out the DC power jack on the MOBO just last night which fixed the 70W power supply problem. I still have the 1.8GHZ processor running at 789MHZ. Even with the power options set to always on and I have all the speedstep stuff disabled. I also upgraded the bios and downloaded fixes for speedstep stuff but nothing seems to work. The batteries won't charge either, but I will have to see if the new DC jack fixed that. You can get one of these jacks on Ebay for about 10 bucks if anyone is interested. I am thinking that it is the processor itself going bad, or the MOBO. Maybe esd is a factor? Also when I booted up from the new DC jack it said invalid configuration. I just hit continue and it booted up fine, but the processor still is all wonky. I need to see if my upgraded Memory is the prob as well. Anyone else have this problem?

Hi, I didn't have the same problem as you guys have but something quiet different, but I needed a new DC power jack and I've bought it through www.laptopjacks.com and I can say it's worth advicing them.
