Operating X200 without battery

2009-06-18, 23:38 PM

i'll be using acronis to clone my hdd tonight.  but my battery still have 3hrs left.  i'll be storing my image to a network drive and just wanted to make sure that there's no sudden battery cut offs.

 

so if i were to unplug the battery pack and just use the AC power brick, would that be ok?

It will work but you loose the "APS" like advantages of having a battery installed.  I really prefer the battery being in to soften and voltage spikes, but to answer your question it will work.

i have also find that overall system performance is reduced when the battery pack is not installed.

without battery the laptop would not operate 100% CPU load.

The information I am about to share was true with the X61 and is likely accurate for the X200 as well.

 

When the battery and AC adapter are attached, the computer actually draws power from the battery and the adapter charges the battery. This way, the computer has a larger reserve of power to tap at any given instance if power needs change.


If you remove the battery and only use a 65W AC adapter, the computer restricts the maximum clock speed that the processor will reach. This is because there are scenarios where the overall system power draw could exceed what the 65W adapter can provide. Hence the why the battery is a good buffer.

 

If you have a 90W adapter, the clock speed will not reduce and you will not have any performance issues.

 

Either way, yes it will work. However consider that if the power goes out or your AC adapter gets unplugged accidentally, your computer will turn off. You have will have to start your imaging process over.

I will suggest that people whom use laptops always should have a working battery installed. You just never know a slight brownout or blackout shuts down your computer and cause you to lose all your unsaved work.

 

Just like buying an insurance, for 364 days you probably never need it, but for that once in a year that you have huge accident, you can at least count on insurance to foot the massive damage bill. 

 

Redundancy is extremely important.
