Battery Life Of The NETBOOK PRO
8.1.5 Battery Life Of The NETBOOK PRO
Many variables affect NETBOOK PRO power consumption and battery life. The
2200 mAh 12.6 V Lithium-Ion battery pack provides 8 to 11 hours of operation,
dependent on backlight level and no use of peripheral cards or attachments. Unlike
batteries using other chemistries, Lithium Ion batteries do not suddenly fail unless
they have been abused in some way. The battery capacity gradually reduces over the
lifetime of the battery. Typically, the capacity of a NETBOOK PRO battery pack
will decline by approximately 15-20% of initial capacity over 400 charge/discharge
cycles. The battery capacity also declines slowly with aging, i.e. in storage.
Conventionally, the NETBOOK PRO battery pack is considered to have reached
'end-of-life' when its capacity has declined to 50% of the pack’s initial capacity.
Therefore, a NETBOOK PRO battery pack will typically reach its ‘end of life’ after
approximately 1000 charging/discharge cycles (although the battery will still work
for some time after this point).
8.1.5.1 Charging Times
The standard NETBOOK PRO battery charging solution does not use trickle charg-
ing or fast charging. The NETBOOK PRO battery pack is charged at a constant rate.
The actual charge time experienced is dependant on capacity of the battery pack and
the ambient temperature. The approximate charging time is 3 to 4 hours.
8.2 ActiveSync Connection Problems
Using Windows® 95/98/NT 4.0
This section is a guide to troubleshooting connection problems between a
NETBOOK PRO and a PC running Windows
® 95/98/NT 4.0 and ActiveSync. It
also presumes you have already gone through the online help documents that come
with ActiveSync, and still have no success in linking. A basic knowledge of using
the NETBOOK PRO and Windows 95/98/NT 4.0 is necessary. For information
about using Windows 95/98/NT 4.0, check your Windows manual or contact the
Windows helpline.
