Hazardous Voltage; Avoid Electrostatic Discharge; Power Supply Unit - Packard Bell dot Disassembly Manual

Hazardous Voltage

There is hazardous voltage present inside the
notebook when it is connected to an AC supply,
even when the notebook's power switch is off.
Exposure to hazardous voltage could cause
personal injury. To avoid risk of injury, contact an
Authorized Service Provider for proper
(un)installation of optional hardware devices.

Avoid Electrostatic Discharge

Electrostatic electricity can easily damage circuit
cards and integrated circuits (ICs). To reduce risk
of damage, store them in protective packaging
whenever they are not installed in the system.
Add-in cards can be extremely sensitive to
electrostatic discharges (ESD) and always require
careful handling. After removing the card from the
notebook, place the card flat on a grounded,
static-free surface, component-side up. Use a
conductive foam pad if available, but not the card
wrapper. Do not slide the card over any surface.
Before you install or remove memory modules,
video memory, disk drives, circuit cards or other
devices, protect them from static electricity. To do
so, make sure the notebook's power switch is
OFF. Then, unplug the notebook's AC power cord.
Before picking up the device you (un)install, you
should wear an anti-static wrist wrap (available at
electronic supply stores). Be sure to connect the
wrist wrap to an unpainted metal portion of the
notebook casing. As an alternative, you can
dissipate electrostatic build-up by touching an
unpainted metal portion of the notebook casing
with one hand. Then touch the device you are
(un)installing with the other hand, and maintain
continuous contact with it until it is (un)installed in
the notebook.

Power Supply Unit

Under no circumstances should you attempt to
disassemble the power supply. The power supply
contains no user-serviceable parts. Inside the
power supply are hazardous voltages that can
cause serious personal injury. Always return a
defective power supply to the dealer.

WARNING
Ensure that the notebook is disconnected
from its power source and from all
telecommunications links, networks, or
modem lines whenever the casing cover
is removed. Do not operate the notebook
with the cover removed.
AVERTISSEMENT
Assurez-vous que le système est
débranché de son alimentation ainsi que
de toutes les liaisons de
télécommunication, des réseaux, et des
lignes de modem avant d'enlever le capot.
Ne pas utiliser le système quand le capot
est enlevé.
WARNUNG
Das System darf weder an eine
Stromquelle angeschlossen sein noch
eine Verbindung mit einer
Telekommunikationseinrichtung, einem
Netzwerk oder einer Modem-Leitung
haben, wenn die Gehäuseabdeckung
entfernt wird. Nehmen Sie das System
nicht ohne die Abdeckung in Betrieb.
ADVERTENCIA
Asegúrese de que cada vez que se quite
la cubierta del portátil, el sistema haya
sido desconectado de la red de
alimentación y de todos lo enlaces de
telecomunicaciones, de red y de líneas de
módem. No ponga en funcionamiento el
sistema mientras la cubierta esté quitada.
WAARSCHUWING
Zorg er voor dat alle verbindingen van en
naar de notebook (stroom, modem,
netwerk, etc) verbroken worden voordat
de behuizing geopend wordt. Zet de
notebook nooit aan als de behuizing
geopend is.
AVVERTENZA
Prima di rimuovere il coperchio del telaio,
assicurarsi che il sistema sia scollegato
dall'alimentazione, da tutti i collegamenti
di comunicazione, reti o linee di modem.
Non avviare il sistema senza aver prima
messo a posto il coperchio.
