What to do if win10 solid state drive takes 20 seconds to boot?

Many netizens have already used SSD (Solid State Drive) and upgraded the Win10 system. The computer hardware configuration is high and the system is new enough. However, they find that the computer is still very slow to boot. What is the reason? How to deal with it? The following article will introduce it to you, I hope it will be helpful to you.

Generally speaking, this has nothing to do with the configuration of the computer itself. It is often caused by the following aspects.

1. 4K is not aligned

Nowadays, most new installed machines will choose to install SSD (solid state drive), and if you want the solid state drive to exert its due strength, 4K alignment It is a must-do operation. 4K alignment needs to be completed during the partitioning process, which can be done with the help of the Win10 installer (it will automatically be 4K aligned after partitioning using the Win10 installer) or special partitioning software (such as DiskGenius). It should be noted that many partitioning software do not check "Align partition to an integer multiple of this number of sectors" by default. Users need to manually click and select the corresponding alignment value (sectors 2048 and above are acceptable) .

# After 4K alignment, the system responds quickly, runs smoothly, and all operations run smoothly. If you find that the system is stuck and the computer is sluggish, the first thing to check is whether the 4K is aligned (you can use another tool AS SSD Benchmark).

#2. AHCI is not enabled

In addition to using 4K aligned partitions, the AHCI mode must also be enabled in the BIOS to function SSD real performance. For new motherboards, this setting is enabled by default at the factory, but it is still recommended that friends check it themselves before installing the system. The location is generally under the "Advanced" → "SATA Type" item. Of course, the name may be slightly different, so you can be flexible in this regard.

3. GPT partition format is not used

GPT is a new set of hard disk partition modes. Compared with traditional MBR, In addition to supporting larger disks, GPT partitions also allow the hard disk partition table to automatically complete redundant backups, greatly improving the stability of the system itself. The most important thing is that the Win10 system has more optimizations for GPT partitions and can achieve magical countdown startup. It should be noted that GPT partitioning also needs to be performed during the partitioning process, and converting the partition type may cause hard disk data loss, so data backup needs to be performed in advance.

4. Dual graphics cards

If the startup of Win10 is still very slow (more than 40 seconds) after following the above method, Then you need to check whether dual graphics cards are installed in the system. Dual graphics cards have a high degree of application in the DIY field, and some high-end notebooks often use this design. However, win10 has not been very compatible with dual graphics cards, especially A cards, where the problem is even more obvious.

The solution is:

1) Press the key combination [win r] to enter the run window, enter "Regedit" to enter the registry editor;

2), click "Edit-Search" and search for "enableULPS";

3), set all searched key values ​​to "0 "(those with _NA suffix are also counted), then restart the computer;

4), right-click a blank part of the desktop → "Display Card Properties" → "Power" → "Switchable display card all settings", uncheck the checkbox before "There are other power saving methods", and then change "Insert" to "Highest performance";

5), restart the computer again, and the boot speed should have returned to normal;
