Notebook Problem

In our computer shop, we noted increasing numbers of notebook being repaired for various problems, and except virus infection, say about 4 out of ten have either: 1. dead hard drive, 2. dis-function of flexible wire connection to LCD display, 3. Broken LCD, 4. malfunction memory module, 5. weak battery 6. dead mainboard

HDD Most of these hdd still detected by mainboard and still accessible in DOS environment but when we try to install operating system they kept on crashing. This is the sign of malfunction of moving parts inside [the platter, head stack assembly, or bearing]. Low level formatting only save 1 out of 100 in this case. The only solution was to replace it.

Flexible Wire Connection. For obvious reason this too happen to devices like clamshell-type mobile phone. I assumed because of open-close moving, the trace inside flexible wire became disintegrated in microscale. In few cases the wire still working, but has loose connection to mainboard. Tighten the screws and they are back in business. In1st case, it has to be replaced.

LCD I can’t figured how. White lines vertical or horizontal or both- burnt color appeared. From what we experience this can be interchanged with other type of same brand. Replacing it with brand new will cause about one fourth of notebook price.

Memory Module Just like what usually happened to desktops, cheap memory will not last long. In most case the owner had installed additional module and it was the one which had failed first.

Battery This is common to dry cell type. Overcharge, mid-level charge will weaken it, and it’s there in the manual book. There is nothing could be done except to replace it.

Dead Mainboard If this is happen to and old machine then you can say it has reached its lifetime, but if it’s to 1 – 2 years old machine then is should be for other reason(s). In other words, this case usually happen to old expensive brand or rather new cheap machine. I always suspect excessive heat played its part. In cheaper notebook, you may have noted the temperature comes out the exhaust window was so. At the bottom part of the machine, well, as of it’s you can use it to iron clothes. This indicates the excessive heat building inside and in mainboard surroundings is much greater.

The Tips on how to prevent them: Buy a well known brand. Those well experienced manufacturer had invested their time and money to find optimum combination of each important parts, use only Grade-A parts, perform continuous read-write testing for days, making system that generate less heat, re-write drivers to fix bugs and good after sales service.Lighter Operating System. It’s good to have your notebook not run in full-speed all the times. Most newer model have Windows Vista pre-installed many owner complained about poor performance and asked to replace it with Windows XP. And even if your system can run Vista without any problem, it still used greater resources and your machine must work harder than with XP. It surely going to shorten the lifetime.Treat the battery well. Avoid overcharging and only recharge after it drains out. If you are at home and using it for long hours, you can remove the battery and using only adapter. Avoid excessive force. No matter how strong it made up, notebooks should always be considered as a delicate device. Swing the display gently. Make sure it powered off. Always do this before you put it into its bag, as your operating system may have problem shutting down. You thought it was powered off, put it into the bag, the heat got nowhere to go & it will toast everything inside.
You surely don’t want this to happen. Install same brand of memory [RAM]. There has been issues of bad performance in using different brand and size. So if you decide to add it, obtain the one with same amount, that is if you have 512MB installed, add with another 512MB same brand. Using notebook on bed may be a fun thing, but wrinkle sheet may block exhaust window, & prevent heat transfer from bottom side.
