Anonymous users2024-02-03Hello, it is recommended that you must install the original Windows operating system, do not use the Ghost version of the operating system, because this kind of operating system is mostly a streamlined system, the stability and compatibility are very poor, and generally do not have AHCI related drivers can not recognize the hard disk in AHCI mode. At the same time, please be careful not to use the driver management software to find the public driver, but should use the operating system CD that comes with the factory or go to the official website of Dell to install the corresponding hardware drivers, so that the stability of your operating system is very high.
At the same time, because the current computer configuration is relatively large memory, so chip manufacturers are also based on the development of 64-bit operating system drivers, it is recommended that you install 64-bit operating system, because after installing the 32-bit operating system, you can not find the relevant hardware driver spring answer program.
In addition, you are reminded to use domestic optimization software as little as possible to carry out the so-called "optimization" or "garbage cleaning", because it is easy to disable the startup operation of the driver or hypervisor or directly delete the driver by mistake and cause problems in the operation of the machine. In addition, the "boot optimization" claimed by this type of software will actually cause many drivers that should be loaded at boot to be disabled, resulting in problems with the related hardware.

Anonymous users2024-01-30Look at the model of about 6500:
Dell Optiplex 9030 (CAD001OPTI9030AIO1300), pre-installed Linux, 23-inch screen, resolution 1920x1080, CPU: Intel Core i3 4150M, main frequency, process technology 22nm, memory = 4GB, hard disk 500GB, built-in ***, core graphics card Intel GMA HD 4600, weight, power supply 180W. ￥5730
Dell Optiplex 9030 (CAD001OPTI9030AIO1308), pre-installed Windows 64bit (64-bit Chinese Simplified Chinese version), 23-inch screen, resolution 1920x1080, CPU: Intel Core i3 4150M, main frequency, process technology 22nm, memory = 4GB, hard disk 500GB, built-in ***, core graphics Intel GMA HD 4600, weight, power supply 180W. ￥6535
Dell Inspiron One Lingyue 2350 (2350-D2338), pre-installed Windows 64bit (64-bit Chinese Simplified Chinese version), 23-inch screen, resolution 1920x1080, CPU: Intel Core i3 4100M, main frequency, process technology 22nm, memory 6GB, hard disk 1TB, no built-in optical drive, core graphics Intel GMA HD 4600, weight, power supply 150W. ￥6499
From the configuration point of view, the CPU of 9030 is more powerful, more built-in, and a little more cost-effective than 2350, 2350 only has advantages in power consumption and weight.
The above is for your reference.
How Dell, one of the richest people in the world, managed to succeed.
When you sleep, it seems that you can wake up by shaking the mouse, and if you are sleeping, you have to press the power button.
First of all, it depends on what the problem of your laptop is, and the software problem can go to the local computer market to find someone to make a system, and the cost is probably a few dozen yuan to a hundred yuan. But if the laptop hardware is broken and needs to be repaired, then you have to look at it, if you go to Dell after-sales service during the warranty period, this is free to repair. But if the warranty period is over, then what do you have to look at? >>>More
Flip the switch on the left to turn it on/off, and the new model no longer uses FN+F2 control. >>>More
Dell's hardware quality can be pretty good, although I later took it apart to see that it was not the best brand, but the whole machine has not been broken in three years. Software problems can generally be called free after sale**, and there are workers to solve them in **, but the most I hear is to reinstall the system, haha. In addition, when our company bought the LCD monitor, we encountered a dot in the middle of the screen, which is not big or small, and you can't see it if you don't look carefully, but Dell refuses to change it, saying that three points are not six points in the normal range, which you have to depend on your luck. >>>More
