This test software

Compared with desktops, laptops are compact and complex, which are not as easy to disassemble and test as desktops. In addition, laptops are relatively high-value products, and few users dare to dismantle them at will, this undoubtedly makes the test difficult for users. Fortunately, there are now a series of software that can help test laptops. These software sources mainly include: one is the commercial professional software used by the laptop manufacturer or accessory manufacturer to check their own products, such as IBM hard disk and battery testing tools; the other is shared software, most of them are tools developed for laptop users or enthusiasts, such as high/low-Test for testing speakers. Today, I will introduce some frequently encountered problems and frequently used test software related to key components of my laptop. Verify CPU authenticity [FAQs] When purchasing a laptop, the main problem we face is to check whether the laptop uses a dedicated mobile CPU. The mobile CPU has a smaller heat value than the desktop CPU, which is conducive to system stability. Note that the information we see in the "my computer" attribute is not necessarily correct due to motherboard issues. [Test Software] 1.fidchs1739.exe This program can be used to determine the Intel CPU frequency, which can be pulled from the Intel website. It can test the processor frequency and bus frequency of Pentium, PII, and piII, this includes the factory frequency and current frequency. 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, including the CPU name, vendor, kernel process, internal and external clock, and local clock. This software can be used to detect non-Intel CPUs. In addition, the chip and motherboard detection will be mentioned in the final comprehensive performance testing tool. Bad display points [FAQs] In LCD, the most critical issue we face is whether there are bad points, that is, the failure points. The invalid pixels are black (not transparent) and white (transparent) or fixed in a certain color, now the quality of good manufacturers have promised "no bad points ". Next, we can also look at the LCD display effect, such as text sharpness and contrast. [Test Software] Ntest.exe This software is actually from Nokia. After running the software, you can switch the solid color of the screen in full screen mode, so that you can easily identify the bad points. In addition, this software can also evaluate the display contrast, text sharpness, color temperature, molar deviation and other professional indicators of the screen through demonstration of different display modes, this software even has the left-right sound channel test function of the speaker. Such a function is really cool compared to its kb head. In fact, if you only want to find a bad point, you can also try the following simple method: set different single background colors in Windows to see if the color is paushed and there are no serious scratches, check the number and position of failure points. You can also use the "canvas" program or "Notepad" program to view the display of the string "mmww" in full screen, especially the effect of edges and corners. Battery Capacity [FAQs] Battery is very important for laptops, and the battery is consumable. Generally, it takes about one year to work stably, and the standby time will be greatly reduced. Therefore, the focus of the test is to check whether the original battery is used. [Test Software] Bat_bar, batterytest, batterymon The software shows how long the laptop's battery can last and the percentage of remaining power. Batterymon can also be instantly expressed through intuitive charts. Because the product is usually tested before leaving the factory, there is residual power in the battery. The measured power cannot accurately display the battery charging capability, the battery capacity must wait until it is fully charged. Generally, the battery standby time of the new laptop is about three hours. In addition, some brands of laptop built-in monitoring programs can be used to count the number of recharges, the use of this detection program can be more convenient to detect. Hard disk memory capture risks [FAQs] For new laptops, hard disks and memory won't have much problem. We should pay attention to some hidden risks, such as damage to the sector and compatibility. For second-hand laptops, due to the service life constraints, these two problems are even more prominent. [Test Software] 1. docmemory This is a four-star software that has won the world's leading zdnet rating. It has advanced memory testing and analysis functions, and users do not need to disassemble the memory, this software can be used to automatically test faults in Simm or dimm memory and JEDEC Standard memory, and detect memory size, speed, quantity, and CPU type; this software has the aging test function. 95% of memory failures on the PC can be captured by this software. The testing procedures include mats, marchb +, marchc-, and checkerboard. The entire process can be operated with the mouse, which is simple and fast. 2. Norton disk doctor in Scandisk, DM, and Norton Utilities In the hard disk testing software, Scandisk is the most convenient (with DOS), but the detection is incomplete. after it passes the test, DM and Norton can be used to scan again. The DM time is long, and the Norton time is short. The scanning process must be smooth and uniform. If a cluster is used too long or the hard disk speed changes frequently or abnormal sound occurs, the cluster must be faulty, even if it passes through. Multimedia viewing results [FAQs] For Multimedia, it is mainly about performance evaluation. In addition, the general laptop has built-in speakers, the quality of which also determines the sound effect of the laptop. [Test Software] 1.3 dmark 2000/2001 This is a well-known tool for analyzing, testing, and reporting the 3D performance of computers, including important reference data such as image quality and texture speed. In fact, data is not the most important, but you can have a perceptual knowledge of the multimedia performance of your laptop from the demo effect during the test, the result is a comprehensive result of the display module and overall performance of the machine. 2. High/lowtest This is a small speaker Effect Testing Software. It mainly tests the High-bass effect of the speaker. It provides 20 kHz ~ 13 kHz high frequency signal and 20Hz ~ Hz low frequency signal test, each signal segment is 4 seconds. When using the "high-frequency testing program", we should note that some people are not sensitive to the signals in this frequency band, so they do not have to be too demanding; when testing too low frequency signals, if you use a small speaker, you may see the phenomenon of "only playing the bass, not smelling the bass. Sound speakers can be heard at 80 or Hz. Of course ~ 60Hz makes it better for you to hear it. Overall test performance [FAQs] Under normal circumstances, the purchase of machines should be aimed at the pursuit of comprehensiveness, and because many modules of the laptop are integrated, the comprehensive performance of the laptop can better reflect its value, at present, there are a lot of software that can collect and evaluate the comprehensive performance information of the laptop hardware. [Test Software] 1. Aida This software displays in detail every aspect of the PC. It supports thousands of mainboards and hundreds of video cards. It can detect PNP devices such as parallel port, serial port, and USB, supports detection of a variety of processors and performance testing. 2. wintune This is a five-star system performance analysis program, it can help you analyze and test your system, CPU, Standard2-D video, OpenGL3-D video, Direct3D3-D video, memory and disk performance, list a detailed report for you. You can also perform online tests. 3. sisoft Sandra Standard This is a powerful system analysis evaluation tool with more than 30 analysis and testing modules, including CPU, drives, CD-ROM/DVD, memory, SCSI, APM/ ACPI, mouse, keyboard, network, motherboard, printer, etc. It can also save the list of analysis result reports. 4. hwinfo, config, etc. Although the functions and operations of the DoS detection tool cannot catch up with the programs in Windows, it can detect laptops without pre-installed operating systems. In addition, testing tools such as 3dmark focus on testing 3D effects, but because 3D has high requirements on machine hardware, it can also be used as a reference for evaluating the overall performance of machines. Now, the basic test software has been introduced in different categories. You can use the latest version on the Internet to study it carefully.
