Today lesson is about Toshiba Satellite L300, Platform number is Inventec: 6050A2170201-MB-A03
What is the problem with motherboard? It starts normally, after starting the laptop; it restarts 2 or 3 minutes later and its displaying and graphic pixels are in disorder.
Notice: Dr-Bios.com suggests, connect the keyboard before starting the laptop
As soon as he starts the graphic problem appeared, it uses the Intel graphic, it displays the graphic but it has problem, in this way, here set the Multimeter in voltmeter, the motherboard has NEC _TOKIN and condensator is 0.9 V, which is not normal. And 1.2 and 1.3 normal voltages are necessary for CPU, What is the cause of this problem? This kind of condensator after sometimes, they stop working .And they don't work properly, the system does not have graphic to display. Some other laptop start immediately but it displays disorder pixels that create the problem on the motherboard. He gives some information about NEC-TOKIN; 0E is the code of the voltage and 907 Microfarad. This works for max 2.5 voltages, and this works in 907 microfarad are equal. He removes this condensator and replace 4 pieces 330 microfarad and after calculating minimum and maximum Microfarad, 330 microfarad is suitable, remove the CPU and Metal piece.
In order to test the system, use AIDA64 software. CPU's temperature are in normal states and CPU's voltage is also normal , Stress Stability Test shows all these, such as; stress CPU, Stress FPU, Stress cache and Stress system memory on the laptop.
There is no visible problem in the voltage then he opens a video the problem isn’t there and its working normally.
