Power manager doesn't show wattage?

2009-02-26, 6:50 AM

Hi,

 

I'm using vista 64 bit and the lenovo power manager 2 (v2.42) doesn't have the option to show wattage when on battery. Is this the norm? or am i missing something? Previous versions do not have this feature too, but when i dual booted in XP i can see the wattage.

I'm running Vista Business 64-Bit and Power manager 2.42.  I can see my wattage just fine.

 

The problem is, you must switch to ADVANCED VIEW.  This will expand the information on the battery tab and include information such as:

 

Full Charge Capacity

Design Capacity

Voltage

Amperage

Wattage (Volts * Amps)

Manufacturer

Serial Number

Manufacture Date

First Used Date

 

Advanced view also enables the Battery Maintenance button.  You can use this to set charge thresholds to prolong the life of your battery.  I use 60% start and 95% stop to minimize top offs.

 

Also for comparison.  I can get as low as 6 watts with a dim screen and slow processor on my x200 Tablet (LED 285nit, SL9400, 320GB 5400RPM HDD).  However, if I turn brightness up or increase my activity; 10+ watts is relatively common.

Finally, thank you for your reply!

 

Well, it turns out that although i can view the wattage by expanding the power manager to advance view, there isn't an option to display it in the little battery icon in the taskbar. When i right click on the icon, my options are only "Remaining percentage", and "Remaining time when on battery".

 

And my wattage never falls below 12W, even with optical drive ejected (physically), integrated graphics, brightness minimum, max battery scheme, wifi on though. Really admire people who reported 8-10W. Even at 12W this computer is already hardly usable with the low brightness =(
