It is rare, but it does happen —- corrosion!
This time it was a Laptop with a ever-so-slightly corroded system board. Once this happens your system with begin to slowly but steadily die. Day after day it will crash more often and you will experience strange periods when your machine won’t even power up.
In this case the screen would back-out after the machine being powered on for about 30-60 minutes. It became worse until it was only after 3-5 minutes that it blacked out. By and by it was discovered that there was a slight bit of corrosion beginning around some components on the system board.
Here is how you can avoid it happening to you:
Corrosion is commonly due to moisture residing in an area over a lenghty period of time. This may happen if:
1) You are living in a humid climate
2) You are living near the sea
3) If liquid was spilled on your machine
If you live by the sea or in an area with a humid climate, you will want to:
– Keep your office of work area well ventilated with a de-humidifier, but do not work with your laptop directly around the unit. Likewise keep the Desktop away from the de-humidifier as well.
– A big must for laptops and Desktops alike is ventilation. Make regular checks on the vents of the the machines and make certain they are dust and dirt free. Get a ventilation tray for your laptop to sit on. These are pretty cheap and keep your laptop extra cool and well-ventilated.
– When you are not using your laptop store it in a dry and cool case. To prevent a build-up of moisture in the case you can keep some of those little de-humidifiers that come in show boxes and electronic equipment. Before you put your laptop away make sure there is not liquid on it – wipe it down with a soft tissue to remove sweat and anything else moist.
If you have spilled something on your machine:
– Do not power it on. Unplug it immediately and remove the battery.
– Get some soft tissue right away and soak up any moisture you see anywhere on or around the laptop.
– If the machine is under warranty and you call the manufacturer of the unit, you risk voiding the warranty all together – and besides there is nothing they can do for you right then and there. (Note: For IBM/Lenovo Thinkpad owners you would be able to call up your service branch and get some tips from them as to how to go about drying the item. For Toshiba and HP/Compaq owners you should be very wary of calling the customer support for this sort of thing – they will most likely void your warranty.)
– If you have decided to get the machine up and running again yourself you should go about obtaining the maintenance manual for the machine you have. Then proceed to dis-assemble the laptop to its bare bone to allow you to thoroughly check and dry all the components. (NOTE: DO NOT attempt to take your laptop apart unless you are completely comfortable with such things!)
– Once you have successfully dried all the components and re-assembled the item, you should place it in a dry, cool and well-ventilated place to sit for a couple days straight. This is should allow any moisture to completely dry up. You can then cross your fingers and press the power button.
