I don't know how many Dell models are. My model is from China. Last time, I changed the fan.It's 45 yuan. You can call it for reference. It should be 50 to 60 yuan
Generally, the fan is 100~400 You can buy it directly, take the computer and ask them to change it for you When buying, you can know the approximate price by asking a few more stores
Hello! The following methods are for your reference: Your USB interface cannot be used (most of it is USB 3.0 interface), which is generally caused by some optimization or security software installed and the USB 3.0 driver disabled.It is recommended that you go to the official website driver page to download the corresponding driver installation. You need to log on to the Dell official website to download the driver: http://www.dell.com/support/drivers/cn/zh/cnbsd1/DriversHome/?c=cn&s=bsd&cs=cnbsd1&l=zh
It is OK to support 500G. At present, the 500G hard disk is the most cost-effective one. You can buy a 500G hard disk to install it, and buy a mobile hard disk box to take out the hard disk in the notebook to form a mobile hard disk for use.
The 1400's video card is broken. This is a common problem with Dell machines. If the fan can work normally, changing the fan can't solve the problem.In order to completely solve the problem, you need to replace a modified graphics card. Replacing the on-board graphics card from G86-630-A to G86-631-A2 can completely solve the problem.The graphic card for rewelding is usually used for a short time, so I suggest replacing it.
