WinBook N4 Pentium 4-M 1.8GHz Notebook

Performance - BatteryMark 2001

Battery Life (minutes) Toshiba 1905-S277 1.6GHz WinBook N4 1.8GHz ASUS T9400 900MHz 239 155 153 | 0 | 48 | 96 | 143 | 191 | 239 | 287

We tested the WinBook N4 in the same manner we have tested all laptops to date. This includes installing Windows 2000 on the notebook in question (as BatteryMark 2001 is not supported under XP) and running BatteryMark 2001 to see how long the system runs under typical usage. We found that the desktop replacement WinBook N4 lasted about as long as the thin and light ASUS T9400 lasted. The two batteries provide about the same amount of mAh, 3600mAh in the ASUS and 3900mAh in the WinBook, but the WinBook battery is an eight cell one while the ASUS battery is a six cell one. Both systems fell short of the run time standard set by Toshiba's Satellite 1905-S277 which ran for 1 minute short of four hours. The WinBook N4's 155 minute up time on battery equated to 2 hours and 35 minutes of usage.

Performance - Startup Times

Addressing some feedback we received recently from readers, this section now includes not only boot time but also the time taken to get out of standby and the time taken to get out of hibernation.

Boot Time (seconds) ASUS T9400 900MHz Toshiba 1905-S277 1.6GHz WinBook N4 1.8GHz 34 36 37 | 0 | 7 | 15 | 22 | 30 | 37 | 44

The boot tie of all three systems we have looked at are fairly similar. The ASUS T9400 was able to boot slightly faster due to the fact that it does not have to initialize internal hardware such as the DVD/CD-RW drives present in the WinBook and Toshiba systems. Nonetheless, the boot time differences between machines was only 3 seconds between the fastest booting system and the slowest. Not a large enough difference to ever notice in the real world.

Out of Standby Time (seconds) WinBook N4 1.8GHz Toshiba 1905-S277 1.6GHz 6 6 | 0 | 1 | 2 | 4 | 5 | 6 | 7

Both the WinBook N4 and the Toshiba Satellite 1905-S277 took exactly 6 seconds to come out of standby mode.

Out of Hibernate Time (seconds) WinBook N4 1.8GHz Toshiba 1905-S277 1.6GHz 16 17 | 0 | 3 | 7 | 10 | 14 | 17 | 20

The WinBook N4 was slightly faster in coming out of hibernate mode, beating the Toshiba system by 1 second. Again, this difference equates into little real world value.
