Since the laptop relative to the desktop, the structure is compact, unlike the destruction and inspection as a desktop, and the laptop is relatively high value, very few users dare to dismantle, which is undoubtedly to users. The inspection brings difficulty. Fortunately, there is now a series of software to help test laptops, the sources of these software mainly include two categories: a class is a laptop manufacturer or accessories manufacturer to test commercial professional software used by their products, such as IBM's hard drive, Battery detection tools; other categories are software, more tools developed by laptop users or enthusiasts, such as high / low-test for test speakers. Today, I will introduce some of the frequent problems and common test software associated with the laptop. CPU distinguishing [FAQ] When purchasing a laptop, the main problem we face is whether the laptop uses a dedicated mobile CPU, and the mobile CPU has smaller heat generation, which is conducive to system stability. It is important to note that because of the problem of motherboard, the information we see from "My Computer" is not necessarily correct. [Test Software] 1. FIDCHS1739. EXE This program can be measured to Intel CPU frequency, which can be pulled down from the Intel website, which can test the processor frequency and bus frequencies of Pentium, PII, PIII, including the factory frequency and current usage, where Intel Processor Frequency ID Utility is used to identify your Intel processor model and key performance data. This is a software that monitors CPU information. Its detecting information includes: CPU name, vendor, kernel process, internal and external clock, local clock, etc. This software can be used to detect non-Intel CPUs. In addition, the detection of the chip and motherboard will also be mentioned in the final comprehensive performance testing tool. Display Find a bad point [FAQ] In the LCD, the most critical problem we face is to see if there is a bad point, that is, the failure point, the pixel of failure is black (opaque), white (transparent) or fixed to a certain The top of the spectrous, now quality, the manufacturer has promised "no bad point". Second, we can also look at the display effect of the LCD, such as literary sharpness, contrast, etc. [Test Software] NTEST. EXE This software is actually NOKIA. After running this software, you can switch the screen full-screen switching, so you can easily identify the bad point. In addition, this software can also evaluate various professional indicators such as display contrast, literary sharpness, color temperature, molar deviation of different display modes. This software does even have the left and right channel test functions of the speaker, so many functions relative to It's 578KB of a head, it is really love. In fact, if you just find a bad point, you can also try the following simple method: set different single background color under Windows, see if the color is flowering, there is no serious scratch, check the loss of failure points, location, etc. You can also use the "Drawboard" program, or "Notepad" program, the full screen looks after the string "MMWW" display, especially the edge and quadratic effect. Battery measurement capacity [FAQ] Battery is very important for laptops, and battery is consumable, and the time that can be stably operates is around a year, and it will be greatly reduced. So the focus of detection is to see if it is an original new battery. [Test Software] BAT_BAR, BATTERYTEST, BATTERYMON These software can show how long the battery is still used, and the percentage of power remaining. BatteryMon can also be expressed in an intuitive chart.
Since the product will be tested before the factory, there is a residual charge in the battery. At this time, the amount of power measured cannot accurately display the charging capacity of the battery, and must wait until fully charged to objectively see the battery capacity, general new The battery standby time of the laptop should be around three hours. In addition, some brands of laptops built-in monitors can statistically charge the number of times, and use this test program to be more conveniently detected. Hard disk memory catch hidden dangers [FAQ] For new laptops, hard disk and memory will not have too much problem, we mainly pay attention to some hidden dangers, such as damage to sectors, compatibility, etc. For second-hand notebooks, these two problems are more prominent due to the restrictions of service life. [Test Software] 1. DocMemory This is a software obtained by world authoritative ZDNET four-star assessment. It has advanced memory test and analysis. The user can automatically test the SIMM or DIMM memory and Jedec standard memory strips through this software. It also detects the size, speed, quantity and CPU type of memory; this software has aging test functions, and 95% of the PC can be captured by this software. Test programs include MATS, Marchb , Marchc- and Checkerboard. All processes can be operated by mouse, simple and rapid. 2. Scandisk, DM, Norton Utilities In the hard disk test software, Scandisk is the most convenient (DOS own), but the detection is not complete, and the DM can be used after it runs. DM is long, and Norton is time consuming. The scanning process must be uniform smoothly. If the cluster area is too long or the hard disk speed changes frequently, the abnormal sound will indicate that the cluster zone must have a problem, even if it passes. Multimedia View Effect [Frequently Asked Questions] For multimedia, it is actually the performance of performance. In addition, general laptops have built-in speakers, and the quality of their quality also determines the sound effect of laptop. [Test Software] 1.3dmark 2000/2001 This is a very famous analysis, test and report tools for computer 3D performance effects, including image quality, map speed, etc. Important reference data. In fact, the data is not the most important, but from the Demo effect from the test, you can have a sense of sensibility to your own laptop multimedia performance, and the result is a comprehensive result of the display module and overall performance of the machine. 2. High / lowte this is a small speaker effect test software. The main test speaker is high, which provides a high frequency signal for 20kHz to 13kHz and a low frequency signal of 20Hz to 200Hz, each signal for 4 seconds. It should be noted when using the "high frequency test program", some people are not sensitive to this frequency band, so it is not necessary to exceed it; when the frequency signal is too low, if you use a small speaker, if you use a small speaker, There may be a phenomenon "I only see the low voice, not a low voice". Good speakers can make you listen when 80 or 120 Hz, of course, if you can listen to it more than 20 ~ 60Hz. Overall performance [FAQ] Under normal circumstances, the purchase of machines should be based on the pursuit of comprehensive performance, and because many of the modules of the laptop are integrated, the comprehensive performance can be more value, There are currently many software to collect and evaluate the hardware integrated performance information of laptops.
