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 :? .
