Notebook has short 
operating time when 
on battery. 
Turn down display 
brightness. 
Check timeout settings in 
Power in Control Panel. 
Check power management 
settings in BIOS Setup. Try 
default settings. 
Battery gauge might need 
calibration. Run HP Battery 
Optimizer from Start menu. 
Certain applications can 
cause excess CPU and 
power usage. (User can get 
Intel Power Monitor from 
www.intel.com and monitor 
CPU load.) 
When playing DVD movies 
on battery power, use Power 
Options in Control Panel to 
select Portable/Laptop power 
scheme. 
When using applications with 
automatic save feature (such 
as MS Word), extend save 
time or disable to reduce hard 
disk access and power 
usage. 
PCMCIA card use can affect 
battery life. Some PCMCIA 
cards draw power even while 
not in use. 
Heavy modem use can affect 
battery operating time.

AC adapter does 
not power 
notebook. 
Try another AC adapter, if 
available. 
AC adapter. 
Motherboard. 
AC adapter cannot be 
repaired, and must be 
replaced. 
Battery indicator is 
inaccurate. 
Time Remaining is an 
estimate based on 
notebook’s power use at that 
moment. It therefore depends 
on current task, and assumes 
power will be used at that 
rate until battery runs out. So 
if notebook is currently using 
good deal of power (such as 
when reading CD or DVD), 
Time Remaining likely shows 
less time than actually 
remains. 
  
Standby/resume    
General problems. Close all applications before 
entering (or allowing 
notebook to enter) Standby or 
Hibernation mode. 
If problem appears after 
installing new software 
(including drivers), uninstall 
that software. Contact 
software vendor for additional 
support. 
  
Notebook resumes 
slowly from Standby 
mode. 
Notebook can take a minute 
or longer to resume if network 
card is installed. Blinking 
cursor appears while system 
is loading and checking 
hardware and network 
connections. When hardware 
is reinitialized, Windows 
desktop appears. 
  
Does not suspend 
to Standby mode as 
expected. 
Notebook won’t suspend if 
connection to another 
computer is active. 
If notebook is busy, it 
normally finishes current 
operation before suspending. 
  
Does not 
automatically enter 
Hibernation mode 
as expected. 
Make sure hibernate support 
is enabled in Power in 
Control Panel. Also, make 
sure Hibernate timeouts 
(Power Schemes tab) for AC 
and battery power are not set 
to Never.
