Problems solved by technology

However, using hot-swapping to remove the same BIOS may also cause damage to some components of the motherboard, so a reliable method is to use a write coder to write the BIOS update file into the BIOS (it is safer to find a computer manufacturer with this service)

Embodiment Construction

[0008] The preferred embodiments of the present invention will be described in detail below, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0009] In one embodiment, the mainboard of the digital TV mobile phone is composed of an uppermost layer of anti-radiation coating, a middle layer of foamed aluminum alloy layer and a lowermost layer of substrate, and the substrate is a double-sided glass fiber board. The anti-radiation coating accounts for 7%-10% of the overall weight of the digital TV mobile phone main board, the described foamed aluminum alloy layer accounts for 21%-29% of the overall weight of the digital TV mobile main board, and the described base material accounts for 21%-29% of the overall weight of the digital TV mobile phone main board. 63%-70% of the overall weight of the motherboard.

[0010] It is further illust...

Abstract

The invention discloses a digital television mobile phone mainboard. The digital television mobile phone mainboard comprises a topmost radiation-proof coating, a middle foamed aluminum alloy layer and a downmost base. The base is a double-side glass-fiber board. A weight ratio of the radiation-proof coating to the digital television mobile phone mainboard is in a range of 7-10%. A weight ratio of the foamed aluminum alloy layer to the digital television mobile phone mainboard is in a range of 21-29%. A weight ratio of the base to the digital television mobile phone mainboard is in a range of 63-70%. The digital television mobile phone mainboard has the characteristics of good radiation resistance, shockproof performance and long service life.

Description

technical field [0001] The invention relates to a main board of a digital TV mobile phone. Background technique [0002] The CPU frequency set in the CMOS of the jumper-free motherboard is wrong, which may also cause a failure to display. For this, just clear the CMOS to solve it. The jumper for clearing CMOS is generally near the lithium battery of the motherboard, and its default position is generally 1, 2 short circuit, as long as it is changed to 2, 3 short circuit for a few seconds, the problem can be solved. For the old motherboard, if the user cannot find it To this jumper, just remove the battery, wait for the boot display to enter the CMOS setting, then shut down, and reinstall the battery to achieve the purpose of CMOS discharge. The motherboard cannot recognize the memory, the memory is damaged, or the memory does not match, which will also cause the fault of no display after booting. Some old motherboards are picky about memory. Once the memory that the motherb...
