shorten  the  life  of  the  battery  and  can  also  pose  a  safety  hazard.  Do  not  let 
rechargeable  Lithium-Ion  batteries  completely  discharge  or  store  these  batteries  in  a 
discharged  state. 
Heat  and  product  ventilation 
Computers  generate  heat  when  turned  on  and  when  batteries  are  charging. 
Notebook  PCs  can  generate  a  significant  amount  of  heat  due  to  their  compact  size. 
Always  follow  these  basic  precautions: 
v  Do  not  leave  the  base  of  your  notebook  computer  in  contact  with  your  lap  or 
any  part  of  your  body  for  an  extended  period  when  the  computer  is  functioning 
or  when  the  battery  is  charging.  Your  computer  produces  some  heat  during 
normal  operation.  Extended  contact  with  the  body  could  cause  discomfort  or, 
potentially,  a  skin  burn. 
v  Do  not  operate  your  computer  or  charge  the  battery  near  flammable  materials  or 
in  explosive  environments. 
v  Ventilation  slots,  fans  and/or  heat  sinks  are  provided  with  the  product  for  safety, 
comfort,  and  reliable  operation.  These  features  might  inadvertently  become 
blocked  by  placing  the  product  on  a  bed,  sofa,  carpet,  or  other  flexible  surface. 
Never  block,  cover  or  disable  these  features.
You
  should  inspect  your  desktop  computer  for  dust  accumulation  at  least  once 
every  three  months.  Before  inspecting  your  computer,  turn  off  the  power  and 
unplug  the  computer’s  power  cord  from  the  electrical  outlet;  then  remove  any  dust 
from  vents  and  perforations  in  the  bezel.  If  you  notice  external  dust  accumulation, 
you  should  also  examine  and  remove  dust  from  the  inside  of  the  computer 
including  heat  sink  inlet  fins,  power  supply  vents,  and  fans.  Always  turn  off  and 
unplug  the  computer  before  opening  the  cover.  If  possible,  avoid  operating  your 
computer  within  2  feet  of  high-traffic  areas.  If  you  must  operate  your  computer  in 
or  near  a  high-traffic  area,  you  should  inspect  and,  if  necessary,  clean  your 
computer  more  frequently. 
For  your  safety  and  to  maintain  optimum  computer  performance,  always  follow 
these  basic  precautions  with  your  desktop  computer: 
v  Keep  the  cover  closed  whenever  the  computer  is  plugged  in. 
v  Regularly  inspect  the  outside  of  the  computer  for  dust  accumulation. 
v  Remove  dust  from  vents  and  any  perforations  in  the  bezel.  More  frequent 
cleanings  might  be  required  for  computers  in  dusty  or  high-traffic  areas. 
v  Do  not  restrict  or  block  any  ventilation  openings. 
v  Do  not  store  or  operate  your  computer  inside  furniture,  as  this  might  increase 
the  risk  of  overheating. 
v  Airflow  temperatures  into  the  computer  should  not  exceed  35°  C  (95°  F). 
v  Do  not  use  non-desktop  air  filtration  devices.
CD  and  DVD  drive  safety 
CD  and  DVD  drives  spin  discs  at  a  high  speed.  If  a  CD  or  DVD  is  cracked  or 
otherwise  physically  damaged,  it  is  possible  for  the  disc  to  break  apart  or  even 
shatter  when  the  CD  drive  is  in  use.  To  protect  against  possible  injury  due  to  this 
situation,  and  to  reduce  the  risk  of  damage  to  your  machine,  do  the  following: 
v  Always  store  CD/DVD  discs  in  their  original  packaging 
v  Always  store  CD/DVD  discs  out  of  direct  sunlight  and  away  from  direct  heat 
sources 
v  Remove  CD/DVD  discs  from  the  computer  when  not  in  use
