The vio notebook has developed so much in the chinese market that it is powerful and popular, that in the process of using the vio notebook we inevitably have a number of common problems that bother us, but if we send it for repair, how can we solve them without the repair shop? Let's take a look at the maintenance of the vio notebooks。
Vario's notebook maintenance:
1. No power:
The electric circuits of the vio notebook need to be matched by the corresponding voltage to form a complete open circuit, and the voltage needs to be measured to obtain the measure of dvd, h8vdd5, +5vas, +5v, +5vs, vcca, vccp, +3v ich, +1. 8v ich+12v, ddr2. 5v, +3v lan, +3vcllk66, +3vclkcpu, +3vclkpci, 3v usb。
In addition, we need to understand the signals associated with the opening circuits of the vario laptop power, which are essential to pcirst, pwrsw, h8-reset, iderest, vcc5m on pmh4, theermda, h8 sda1, etc. All vio notebooks and their master boards need to follow certain principles to function properly, which are the architecture principles of the vio notebook master board。
The charge was not shown at the time:
The failure of the vaio notebook, which is charged but not shown, may be caused by a number of circumstances, the first being the failure of the voltage, and we first have to check the voltage of the vaio notebook for other reasons if there is no problem with the voltage;
The second is probably because of the problem with the vario laptop signal, which we measure on a case-by-case basis. The signals are smb clk, cpu stp, pci stp, clk enable, usbclk 48m, lpcclk h8 and so on. Once the signal light is measured, the maintenance of the vario notebook can be done. In other cases, there are good or bad memory problems with vio notebooks, good or bad graphic cards, good or bad signal output from the lcd screen, etc。
This is the profile of the common malfunctioning of the vio notebooks, and we can easily find the cause of the malfunctioning and maintenance of the notebooks。
