NOTES:
1 The Dell Latitude CS/CSx portable computer does not support some memory modules from older models of Dell portable computers, such as the Latitude CP, XP, XPi CD, or LM. It only supports SDRAM modules and does not support EDO memory modules.
2 Battery performance features such as charge time and life span can vary according to the conditions under which the computer and battery are used.
3 Measured with the hard-disk drive in head-parked position.
4 Latitude CS system with standard battery
