SP2: High power consumption after standby
Hi all
I got some problems after installing service pack 2. I hope you can help me with this one: I have an intel centrino laptop with windows xp professional and recently installed service pack 2 on it. Under normal circumstances, the laptop does not get very hot, and does not turn on the fans. Now, whenever it wakes up from standby or hibernation, it will get very hot and run the fans almost constantly, with greatly increased noise and battery consumption. Only after a reset will the power consumption be back to normal. This will happen even if no programs are runnning, and the task manager reports almost no processor activity, or memory access. No unusual disc access either. Using the SpeedswitchXP utility I found out that before standby, the processor speed will always stay below 600Mhz. After waking up, the speed will frequently spike to 1396Mhz. The problem persists with or without SpeedswitchXP runnning. How can I fix this? Thanks for any help |

Stuff like this is often corrected by a BIOS
update for the laptop. Alternatively, search support.intel.com for Speed Step info and problem resolution. SP2 probably overwrote a system .DLL, driver or something else that Speed Step uses. http://support.microsoft.com/default...b;en-us;290301 "Maurice N ~ MVP" wrote in message ...

Sadly I was unable to solve this problem so far. I indeed found a newer bios update, but it did not change anything I found no article on support.intel.com that seemed to fit my problem, but I tried to make sure all drivers are up-to-date. I also used the intel inf installer and then went throught each component in the device manager and clicked "update drivers". I tried the Intel Processor Frequency ID Utility, which said my processor was not supported by it and I should instead use the Intel Processor Identification Utility Using this, I indeed got different reported speeds before and after standby. My Processor is recognized as: - Intel Pentium M Processor 1400MHz - with reported Speed 0,95Ghz, 397Mhz Bus, before standby - with reported Speed 1.40Ghz, 400Mhz Bus, after standby Is there anything left I could do to pin this problem down? It really makes working with my notebook difficult. |

Don't know really where to go from here
except the following: if it's still under warranty, send it in if it came with CD's to restore it to "out of the box" condition, do it and don't apply SP2. If you're a careful user, you don't need it. "Christoph Mueller" wrote in message oups.com... V Green wrote: Stuff like this is often corrected by a BIOS update for the laptop.
