Ask the guys who repaired their notebooks around you, the motherboard issues may be the most commen problem of . The author’s first notebook also dead as the motherboard problem. General board problems reasuly the machine unbootable. Motherboard problems usually cases short-circuit of IC (integrated circuit).

We usually should change the motherboard when it is broken. The motherboard prices accounted for 1/4 of the laptop price, so the motherboard problem is the most expensive problem. We need to take attention that do not let leak fluid into the motherboard (we often do this). Do not refresh the BIOS if neednot. In addition, the motherboard is the breakdown by high voltage also happened frequently. If in the electricity peak or just to restore the electricity blackouts, during lightning storm, I propose to use -powered, do not access home electricity.

2: Hard Disk

The laptop hard drive is more unbreakable than PC hard drive, but they are still afraid of falling repeatedly. Take a look at the label that prompt us to do not throw it. Why? The notebook hard disk is smaller than PC, but the principle is the same, and also due to the complex composition of electronic components. Although the manufacturers optimize the laptop hard drive break quality. Because of its own composition, it is fear of shock. Remind you, in the bumpy transport, do not use notebook. Be careful not to fall to the ground when place your notebook on the table. As the laptop hard drive is cheap, the information inside is priceless.

Pay attention Do not let the books hit a hard object. When accidentally dropped on the floor, LCD is also often bear the brunt. The large LCD value is also a quarter of machine, and it is difficult to repair it but buy a new one.

4: Strings parallel interface

These interfaces do not support hot swap. It is easy to burn the string parallel when plug the USB port or other sevice in power on. Even worse, resulting in short-circuit board scrap. Although changing string, parallel port is a not too expensive, it is troubleful. There may be someone would say: we are now almost not using the strings parallel port, let them go bad. But the notebooks for engineering debugging that can not lack of the two interfaces.

5: Touchpad

In Summer our hands are dirty and wet. Touch pad with your fingers will make the coating above soon disappear, shorten the life of touchpad and keyboar. So we should wash and clean our hands before open the lapop?
