1. If you are not able to read the disc or read the disc, you don't think it is the optical drive. Many times, the laser beam is not completely transmitted because of the dust on the bald head. The optical drive does not have much technical content, so open the case and do some cleaning, most of which can be reused. Be careful when handling. The coating on the surface of the bald head is relatively fragile. When cleaning, you should not use too much force. You can't get too much ethanol.
2. Maybe you have been "electricized" by the computer. That is because the insulation paint on the exterior of the chassis has been removed or the socket is not grounded. In general, static electricity does not have much impact on the computer. But if there is too much static electricity, there will still be some minor problems. For example, some very close solder joints cause a short circuit to cause a restart and so on. So if you have a friend who is "electric", you can consider grounding the chassis, which is much better.
3. If the integrated sound card of the motherboard is broken, consider buying a new sound card. If you change the crown of the 8738, your motherboard is the model after 845, there will be a problem, that is, the shutdown is selected, the machine is restarted! In addition, the friend of the innovative SB5.1, this model has no drive under VISTA. Some netizens have done one, but compatibility is a problem, often blue screen. The innovative sound card is only 7.1 or above, and can be used in VISTA, but there is no EXA effect.
In addition, some brand card sound card drivers, even if you find the right version of the driver software on the Internet, can not be installed, or installed a small speaker but it does not sound, you must go to its official website to go Use, it is estimated that the specific settings are made, very depressed. Especially Lenovo!
4. The current chassis generally has a front USB interface. Sometimes U disk and MP3 can be used normally, but the camera and mobile hard disk can not be used, prompting "unrecognized USB device". This is normal. When using the camera, it is best to insert it on the port behind the chassis. The data cable of the mobile hard disk generally has two connectors. It is recommended to connect it all the time to ensure the voltage is stable, and it is better to connect it later. Because the front is connected by wires, sometimes a little contact will affect it. If the system displays a "USB device surge" in use, it proves that your motherboard has a problem. If you have not passed the warranty period, just change it.
