X60 power problem...

Hello folks, I'm a X60 user here.

I am currently experiencing some problems here. When I take out the battery and try to run on AC power, the T2400 (1.83Ghz Duo core) refuses to run at 1.83GHz. Instead, it runs at 987Mhz (I think the SpeedStep kicked in or something).

I need to have the battery plugged in, together with the AC power plugged in, before my X60 will run at full speed (1.83GHz).

I have checked my power settings, and even at "Maximum Performance" profile, this problem still exists.

I have emailed IBM technical support, and their engineer claims that the laptop needs to "buffer" the power using the battery to provide for operation at full CPU speed.

Are any of you folks around here experiencing the same issue, or is this supposed to be normal?

Thanks for reading.

 

if u still curious and really want to hear ur fan make some noise, download the notwbook hardware controller, it allows u to manually change the min multipilier and max muliiplier along with cpu voltage at any given multiplier

 

Hi seanlee. The issue at hand here is that I am unable to run my laptop CPU at full speed without the battery being plugged into the laptop.

I am thinking that this is a tad abnormal, as my old A20p is able to run at full speed without the battery. I have a friend with an Acer Duo Core laptop who is able to run his laptop CPU (T2300, 1.66GHz) at full speed without the battery plugged in.

Is this an engineering design issue of Lenovo, or is there something wrong with the power management software, or is it just me?

Thanks for reading.

 

Does anybody here encounter the same problem with the X60, or am I the only X60 user around here?

 

Well I have an x60s en route but I dont understand why you care if the battery is in or not.. What difference does it make?

 

yes, that is what i am suggesting.. try the notwbook hardware controller, with that, you are able to control ur cpu speed manually and then you can tell whether it is a software issue or a hardware issue.
