LG S1 CPU strange behavior after hibernation

Hi,

I have a LG S1-M555P (Portuguese version) and I'm having some problems whenever I resume from hibernation. No matter what I do, the CPU speed it's always at 50% (997,5Mhz in this case cause it's a T2400). Even plugged to the wall, maximum performance enabled in Notebook Hardware Control and runing two instances of SuperPi the CPU just refuses to go full speed. Only after a reboot it goes back to 1833Mhz.

I find this annoying as I use (used ) to go hibernation instead of switching off.

I wonder if this is a Windows bug or laptop/bios bug…


Any feedback?

Edit to fix the CPU speed 1833 instead of 2833Mhz

 

i had the same problem. Installing battery miser from the cd which came with the laptop fixed the problem for me...

 

Tried that, but no avail

 

Try going to Sleep mode instead of Hibernation. It's pretty much the same thing hibernation stores your data on the hard drive and sleep in memory.

Besides from that i don't know why it's behaving like that. Sounds pretty strange.

 

I had a similar issue with a p4 from averatec.

It was a bit different actually, but maybe worth sharing

The CPU was a NON mobile p4 3.00 Ghz.

Whenever I was going into standby, when coming back, the CPU reported as being 2800Mhz, but was significally slower (slower like not getting half the FPS I usually get in my fav. games.)

Hibernation, shutdown or restart solved the problem. The CPU then reported its full 3000Mhz. Never found any fix for it!

 

Hi MountainSnake,

I'm having the same problem. I tried different versions of Battery Misery and also uninstalling it but the problem still exists. Did you able to find any solution for this issue?

 

Hello!

Nope, I gave up and just live with that

I'm wating that LG wakes up and give us a fix to this issue as well as a driver for the x1600 that supports Powerplay. But... LG is very lazy and slow to give us updates...

 

Last week I took my laptop to the local LG reseller service center and proved them the problem with cpu-z and super-pi. They will report this issue to LG. Hopefully we will get the fix soon. (It might be a bios update.)
By the way, there was an ASUS laptop with Core Duo at this service center and we did the same test. After hibernate everything went fine. So this is not related to Windows or Core Duo. This is a an LG problem...

 

Recently LG released a BIOS patch for this issue and yesterday local LG service center upgraded my BIOS. Now everything works fine.

 

Problem is LG doesn't have repair center here. They want me to send the laptop to Holland yeah, right, only because a bios update.

LG support is very poor. Think twice before you buy...
