Because hardware installation error, not compatible or hardware lenovo ideapad g465 laptop keyboard damage wait for a reason, it is apt to cause the hardware error, leading to the light is not work normally, heavy then system will not work fault. Encounter this kind of situation, once only through the POST self-checking of BIOS alarm warning tone, hardware substitution method or through the DEBUG card to find the cause of the problem. But these methods, use rise is not convenient, but also to the user's professional knowledge is also the demand is higher, for ordinary users do not apply.
To solve this problem, now the motherboard manufacturer to join a lot of humanized design, with convenient user fast and accurately judge the cause of the problem.
For example, now many motherboard special design the hardware and electric self-checking fault language broadcast function. With asustek "POST the reporter" as an example, the function mainly by winbond of W83791SD chip, with asustek design chip combination and become. Can monitoring CPU voltage, CPU fan speed, CPU temperature, lenovo ideapad g460 laptop keyboard casing fan speed, power supply fan is failure, chassis invasion of warning, etc. In this way, it is better to keep the computer the best working condition. When the system has a certain equipment trouble, POST the reporter can use voice remind the parts out of the fault.
In the team of the hardware fault alarm, some main board companies have their own very original design. Such as msi motherboard, with the four LED to reflect the malfunction of the motherboard. And some main board is simply introduced earlier Debug mapping team of the wrong CARDS wrong technology, using a more direct digital tube to indicate the malfunction.
In addition, many manufacturers for lenovo ideapad b470 laptop keyboard the mainboard design the AGP protection circuit, in addition to the graphics protection besides, protection circuit with a LED light-emitting diodes, to tell the user fault is caused by the graphics card.
