The notebook’s battery life was measured with Battery Eater Pro 2.60. The program acted up a little, reporting overstated battery charge levels:

The test was performed at the maximum screen brightness in the following modes:

• Classic (the system bears the maximum and evenly distributed load)
• Reader’s test (the pages are scrolled through each 15 seconds)
• DVD mode (a DVD movie is launched in Battery Eater’s Idle test mode)

When the CPU is not used to the full, the battery can last for quite a long time. But as soon as the CPU begins to work in earnest, its charge is consumed almost in a moment. Well, the two hours of autonomous work in the Classic mode is not actually “a moment”, yet we might expect better results from an ultra-compact model intended for field conditions. The notebook almost delivers the declared 4.5 hours in the Reader’s mode, though.

Here are the battery discharge diagrams for the different operation modes.
