Transportation Precautions
To prepare the Notebook PC for transport, you should turn it OFF and disconnect all external peripherals to prevent damage to the connectors. The hard disk drive’s head retracts when the power is turned OFF to prevent scratching of the hard disk surface during transport.
Power (DC) Input
The supplied power adapter converts AC power to DC power for use with this jack. Power supplied through this jack supplies power to the Notebook PC and charges the internal battery pack. To prevent damage to the Notebook PC and battery pack, always use the supplied power adapter. If you must purchase a replacement, it’s critical to purchase the correct replacement or get a universal adapter that properly matches for a snug fit and also has the correct voltage. If you do not have the correct cord, you could cause serious damage to both the power cord and the motherboard.
Using AC Power
Your Notebook PC comes with a universal AC-DC adapter. That means that you may connect the power cord to any 100V-120V as well as 220V-240V outlets without setting switches or using power converters. Different countries may require that an adapter be used to connect the provided US-standard AC power cord to a different standard. Most hotels will provide universal outlets to support different power cords as well as voltages. It is always best to ask an experienced traveler about AC outlet voltages when bringing power adapters to another country.
WARNING! DO NOT connect the AC power cord to an AC outlet prior to connecting the DC plug to the Notebook PC. Doing so may damage the AC-DC adapter.
Other Do’s and Dont’s
DO use a cooling pad or laptop pad which has a cushion on one side for your lap and a flat surface on the other side for your laptop to sit on and get proper cooling / ventilation.
Do blow dust out of it occasionally with compressed air or have done professionally.
DON’T take a household vacuum to your laptop or desktop computers. Static electricity builds up around the end of the hose and can fry components.
DON’T use on your lap or bed blocking air vents unless using a pad of some sort as mentioned above.
DON’T move notebook around while the power cord is still attached.
DON’T leave power cord attached and unattended if the cable is running across the floor where a child or large dog can trip the cable and break the DC Jack and/or power cord.
DO be careful where you place your laptop so it’s not stepped on or crushed. LCD/LED screens do not crack themselves. Very little pressure from the back can cause it to break and crack. Be careful how you pack your bag.
Ignorance is no excuse
Even though you may have used a laptop/notebook for many years the same way with no problems, you’ve been lucky pushing the limits. Taking the above precautions can prolong the life of your laptop/notebook. Ignorance can void any warranties. Avoid DC Jack repairs, screen repairs, etc.
After DC Jack repairs
After the DC Jack is re-soldered, it’s not the same as factory assembled. You got it repaired because it’s broken, so it is not fused to the board with machines like the factory quality, so it will take a less force to break than it did the first time, so you must especially be extra careful.
