Thermal testing on Lenovo ThinkPad E455

Here we test the ThinkPad E455 notebook actual thermal conditions . Our testing method is still room temperature at 28 degrees Celsius , so this notebook run Furmark pager pager comes with software and AIDA64 program , so that the GPU and CPU are working at higher loads , especially GPU, almost is running at full speed . Then after 20 minutes , respectively, to see this notebook internal core temperature and body surface temperature.

Core temperature under high load condition

Surface temperature , we use professional equipment for temperature detection notebook cooling performance testing. To help us observe the temperature distribution of the whole situation, we get the temperature distribution through the instrument to detect , record and mark various parts of the temperature , illustrated as follows.

how to disassemble the Samsung 900X laptop

The ultra-thin models is the only ultra-thin notebooks to compete with the then macbook air in Samsung’s philosophy , but still far from reaching the level of air 900X dismantling the internal structure of the author and design, of course, this is from the machine the point of view of some of the details , do not say that this notebook is very rough, but how to use Apple’s air to compare it really is not reached , both the design and construction of inside wiring and circuit design, etc., but demolition machine is quite simple , here is our detailed dismantling process.

1

There are the top two rubber mat, mat two fixed screws hidden below the surface of D , if the general disassemble friend would never have thought here is that both sides were then marked yellow screw position.

Now remove the D surface.

7

After the first thing apart , of course, is to disassemble the internal battery first , following arrows in the figure is the location of the built-in battery connection line position.

8

Here is the SSD position , of course, must be built into Samsung’s own product SSD solid state.

9

 

If you want to clean up the fan , then now you can start hands, the right of the connection line position Samsung Samsung 900X is two screws fan power , and two fixed fan.

10

The following figure is the location of a wireless network card.

 

11

Under the picture is a memory slot position, the right is factory-installed memory , the left can be upgraded to use their reserved , pre-installed memory is Samsung’s own.

12

 

CMOS battery location is of course the Board below, if I found that Samsung Samsung 900X laptop is unable to save the set time and settings you should see if the motherboard motherboard battery replacement.

13

This is power supply interface module to the right location.

14

All Samsung Samsung 900X open back cover basically all the frequently asked questions to solve, for example, replace the memory and replace the hard drive and cleaned the fan and so on are all in action.
