Notebook battery review

The simple test of HP Mini 2133 battery

Let us take a look at this HP Mini 2133 battery life. From our point of view before the media coverage of such Internet features of this product is any time a free tour of the Internet. This function perfectly or not, is bound to need strong support of the power system. To this end, the HP Mini 2133 is equipped with a three-core 10.8V 28Wh lithium ion battery, the life test results are as follows:

The final results, in the full-torn BatteryMark 4.0.1, the piece of the battery capacity of adhering to a moderate 73 minutes (in this test phase HP Mini 2133 to 70% of the screen from top to bottom, and power management in XP system on the all power-saving features of the option off). If the day-to-day use, can reduce the screen brightness, and then associated with energy-saving function of the operating system, I believe that this battery may last 100 minutes usage time, the same time the satellite A300 battery can work 250 minutes.

Evaluation of a line of the products are excellent, I believe that their long working hours under the state of the performance of body temperature can also be regarded as one of important criteria. After all, no one is willing to use a long period of time may be the Internet version, the body temperature to achieve the degree of fried eggs. To this end, the author carried out in the HP Mini 2133 battery life test, the use of the testo 825-T2 Infrared Thermometer their body temperature was tested (the testing process in the basic maintenance of the indoor temperature around 25 degrees Celsius ).

To the final testing results, HP Mini 2133 battery in the performance of body temperature can be used in this part of “disorder” to make an assessment. The main heat source is basically in the left side of the keyboard and the left side of the fuselage cooling air vents, under the late拆机inspection, the region where is the processor. VIA C7M processor so “hot” performance really let my accident. In addition, the HP Mini 2133 notebook cooling Apple Design and passive fanless cooling body has some similar, are relying on the most metal body heat away. Therefore, HP Mini 2133 in the use of process engineering plastic materials than other Internet users this will bring the feeling of heat.

Might see here, there will be readers to PC Mark05, 3D Mark06 Although the classic, but I do not know this will be the actual performance of the notebook is. You can not come to the actual point? OK, of course, no problem! The needs of readers, that is our goal. Next, I look for you to display the HP Mini 2133 HD video decoding ability.

Proficiency test in high-definition decoding of H.264 I selected encoding format, video resolution of 1280 × 720 specifications “Teenage Mutant Ninja Turtles” to carry out the tests. As shown in the following screenshot, HP Mini 2133 in the performance tests can be described as barely passing. But its good sound, images can be synchronized, the screen is still a natural transition. During playback, HP Mini 2133 occupancy rate of the basic processors in about 90% of the entire process. Used as a VIA S3G UniChrome Pro II integrated GPU, system bus frequency is only 400MHz notebook, this performance is still talking about the past. HP Mini 2133 is HP addtion in netbook to support HP Pavilion DV1000,Pavilion DV3000, DV4000, DV4, DV5, DV7.

As shown in game screenshot, HP Mini 2133 in the performance of the game is also still far from satisfactory. More than two games in high definition is not set up the premise, can smooth out the feeling. Perhaps this author is really some redundant tests, select Netbook “Internet of the” consumer products more convenient for a working or living conditions, most of them has been interested in the age of the game. However, I would like to express here is that, HP Mini 2133 in your spare time can also become a tool for your entertainment pleasure. Perhaps it is not strong enough performance, but occasionally or inadequate.

As HP’s first ultra-portable mobile notebook, HP Mini 2133 HP carried on “with the most user needs for a wide range of mobile solutions,” the commitment to “full-function ultra-portable + + the best experience” to meet the unique advantage of increasingly strong The ultra-portable mobile needs. Its elegant exterior design, whole weight of only 1.19Kg, measuring only 27mm (positive) × 255mm × 165mm, its concise and well anodic alumina shell design, while ensuring at the same time compact and durable machine can reduce the weight of ; in the main configuration, equipped with 1GB or 2GB of memory (only has one memory slot settings), Genuine Windows Vista Home operating system, as well as standard disk drives, can provide fairly good experience.

HP Mini 2133 Review of the advantages and disadvantages:

Advantages :
1, many of the products in the Internet the only model of a metal material, and excellent mold design

2, speaker sound quality on both sides of the screen, in many of the Internet’s most successful products

3, such as 3D DriveGuard with hardware and software protection system hard drive, hard drive data more secure

4, key-bit layout is unreasonable, moderate-size keyboard, excellent use of hand

5, to break the trade restrictions, the provision of 2GB memory as XPS M1530 XPS M1730 PC, 160GB hard drive configuration

1, the normal body process of high temperature than those for similar models, the use of higher ambient temperature

2, pre-installed Vista system, the current allocation of the burden too heavy

3, six-core version does not provide battery life is too short

Dell 4 cells 2200mAh inspiron Mini 9 battery test

Last night I ran a quick test on how long my new Dell Inspiron Mini 9’s battery would last under “normal netbook workload”.

This is the Dell inspiron Mini 9 battery Detail info:

Dell inspiron Mini 9 batetry Test Data capturing:

The ‘remaining capacity’ value from /proc/acpi/battery/BAT1/state and a timestamp were written to a file every minute:

#!/bin/bash  LOG="/home/pn/batterylog"  echo "Battery log, started $(date)" >$LOG  while ((1))  
do    TIME=$(date "+%s")    REMAINING=$(grep "remaining capacity" /proc/acpi/battery/BAT1/state | cut -b 26- | cut -d' ' -f1)

It to a lot of people compare Apple Macbook Air Apple Macbook Air as “the ultimate thin and light” and the ThinkPad X300 is a “no compromise light” here refers to the uncompromising performance, the existence of Apple Macbook Air interface less than , non-standard optical disk drive, memory card there, and many other battery change not regret, and the ThinkPad X300 is more comprehensive.

Light, is the beginning of thin ThinkPad X300 notebook to get the first impression, as is currently the lightest full-featured notebook 13 inches, really deserves. Whole transmission is still the appearance of the “black” appearance of the classic, although the machine has been monotonous black as main color, but it gives the feeling of losing fashion. Its powerful battery is litium battery as VGP-BPS8 VGP-BPS9 VGP-BPS11 VGP-BPS13. The reason why such a thin and light ThinkPad X300 with its use of the material body has a great relationship, X300 using CFRP carbon fiber and glass fiber GFRP as top and bottom of the body material, to ensure a solid body of good control at the same time weight machine.

Thinkpad X300 battery using locking design, unlock the front left is located in the fuselage, one-handed opening and closing of the notebook some difficulties, but the benefits of this design is the security of the notebook have a good guarantee. Of course, there are less than each notebook, I use the X300 for some time, found that the shaft resistance of a small notebook, so I do not know the design of the notebook, or more than the number of opening and closing of cause; In addition, the skin texture of the matte notebook region, if the user the situation in this touching and humid, it is easy to leave a mark, but it is very difficult to remove.

Thinkpad X300 interior design, in the whole extension of the ThinkPad is still the IBM traditional style, in the middle of the screen set up above the 1.3 million-pixel camera, the camera lights next to the keyboard, user-friendly to use in the dark. In the look down in the notebook inside of the two axes are the logo and the Lenovo logo X300.

Relatively rich interface X300 is a big selling point, many people give up Apple Macbook Air and X300 choose one of the major reasons is because this point. Although the X300 compared to the ordinary 13-inch notebook interface or worse, but has been used to meet the day-to-day. The following is a notebook specific distribution of the interface.

In fact, the whole performance of X300 can only say that it is ordinary, Core 2 Duo L7100 processor frequency of only 1.2GHz as thinkpad X200 battery, but the application of the ordinary day-to-day, or enough. In fact, the hardware configuration of the X300’s biggest bright spot is the hard drive is equipped with, X300 uses SSD solid state hard drive, SSD solid state drive uses NAND flash memory, hard drive not have to worry about the collision of data loss, which greatly raised the hard disk data security.

Overall, this notebook is remarkable, 13-inch thin frame, 1.33 kilograms of whole weight, the excellent performance of the hard drive, LED screen, said to be worthy of the ThinkPad family of a milestone for inspiron 6000. But there are also many places with some regret that the general processor performance, interface, or a little weak, especially the price of the current wetlands, or some to be prohibitive. The X300 is currently priced at 24,999 yuan, more suitable for high-end business users, especially for a portable notebook and endurance than the value of this part of users.
