LW65 Weird Power/CPU Problem

Hey All,
Great set of forums you have here, and a dedicated LG forum, hopefully my fellow LG users might be able to offer some advice.

Essentially the problem is reasonably straight-forward and perhaps the solution is as well; but when the laptop is plugged in or connected via the AC powerplug the Bus Speeds fluctuate between 65-75Mhz (Its meant to be stable at 133MHz) this essentially means I end up with about 1100MHz instead of the 2000Mhz im meant to get. However.......when its running on battery power (so not plugged in) it operates perfectly fine...

When I first got the laptop I tested games etc on it to see how the x700 ran, and it ran fine but in the last year ive only really done Office work, Dvds and Web Browsing on it, so it wasnt until last week when I tried Vista and then tried to play a game that I noticed how poorly it ran Vista and the game. In both XP and Vista CPUz reports lowered Bus speed when on AC power.
-Doesn't seem to matter what power management software I use, its the same result on every one.

After trying different drivers/configs/power management software/formats my only thought is theAC adapter has deteriorated/faulty (but I would have thought the Voltage would be fluctuating if this was the case and voltage input is stable).

Anyway I really dont want to send it back for repairs and will be till next week before I can get to another LG Adapter to test my theory but if anyone else has any suggestions by all means please share them, will be very appreciated as this is quite frustrating

Cheers

Dear Oril,

regarding your problem i think this is related to the Bios, check in Bios SpeedStep feature for intel, i think this feature is disabled on your Bios, when it is disabled it will run your CPU on lowest speed your OS cant do nothing, i am having problem with Vista thats it cant control CPU speed, battery miser dont work under Vista, and when SpeedStep feature enabled on Vista it will always run on high speed either on AC or Battery mode, so i disabled this feature in Bios and my CPU run to the low speed always, better than alot of heating.......

 

Hey mate thanks for the reply,

Unfortunately as mentioned, I have the same problem in XP and Vista, additionally, the Phenoix BIOS on these things is the most feature-less BIOS ive ever come across it has 0 options related to speedstep, ACPI or anything. Theres not even a BIOS update I can do.

Im going to call LG tomorrow and see if I can hunt down another power adapter to test it, but Im inclined to think its something internal and in the way power is getting to the FSB so will probably have to send it back (dread) but fingers crossed for a faulty AC cord.

 

Hello.
I'm searching in google for a solution to my problem and I found this forum. Essentially I have the same problem that you have...
I had it once, but at that point I thought that it might be a virus so I formatted it and everything went fine.
I'm gonna do that again now and later I'll tell you if it's really a hardware problem or not.
PS.: My notebook is exactly the same as yours.
Regards
Pesta

 

I've formatted and it went back to normal. It's very weird, 'cause it's the second time it happens and after I format, it goes back to normal...
