Re: Replaceable fuse inside the 170w power supply?

While substituting the resistor inside the connector is a means to fool the laptop into thinking it is connected to a different (usually, higher power) AC adapter, I would NOT recommend doing this. The adapter may not be able to supply enough current to charge the battery and operate the computer at...

Re: Removing password from a 360C?

Power-on passwords can generally be removed by taking out the CMOS (aka, backup) battery. Some of the older systems also relied on inserting a jumper. This has been published in most HMMs. However, if there is also a supervisor password enabled at the same time, this can "brick" the system as it wou...

Re: X230 Users...my X230 doesn't like my 16gb G.Skill memory kit

In other words, there's no separate bank of memory dedicated for video usage; memory is allocated fo...
