Fault symptom:
The system Thinkpad pre-installed with Windows 7 is slow to start. You can right-click the desktop for a long time before it is displayed.
Cause analysis:
Because the pre-installed system contains a lot of Lenovo software and startup items, it is relatively bloated, so it is slow.
Solution:
Part 1: uninstall the program
Choose Start> Control Panel> uninstall program ";
1. The first thing to uninstall is the Norton antivirus service. The names are Norton Internet Security. Find them and double-click them to uninstall them. Do not restart the software after it is uninstalled. We recommend that you use other lightweight anti-virus software, such as Microsoft MSE, red umbrella, and ESET, to save your resources.
2. Two tools provided by Lenovo: Lenovo ThinkVantage Toolbox and Lenovo SimpleTap. These two tools occupy a lot of resources in the Task Manager. Although Toolbox can be disabled during startup, it is always started from time to time. The SimpleTap cannot be started. It occupies a large amount of resources in the processes displayed in the task manager. Therefore, they can be uninstalled, which is not a particularly important tool.
Part 2: Control startup items and system configuration settings
Click the Start menu, Enter "system configuration", and Enter;
Click the "guide" tab, and then click "Advanced options ",
Click the "start" tab. Generally, the hardware console, anti-virus software, power management, and APS hard disk protection are all started. Other application startup items do not need to be started. As shown in the figure, these options must be started, and the rest do not need to be started.
The Microsoft Security Client is Microsoft MSE.
After clicking the button, click "OK" to complete the settings. The system will ask the user to restart. Do not restart the system for the next part.
Part 3: Disable related services
Click Start, Enter service, and press Enter to Enter the page,
We recommend that you disable the following service names:
Diagnostic Policy Service
Diagnostic Service Host
Diagnostic System Host
Program Compatibility Assistant Service
Security Center
Tablet PC Input Service
Windows Backup
Windows Defender
Windows Error Reporting Service
Windows Time
Find these services in this window, double-click them, and then operate them in the order shown in the figure:
Now all the operations are complete. Restart the computer and the above settings will take effect.
Part 4: Switch to exclusive display(Applicable only to ThinkPad models with AMD exclusive display)
Edge E420, E520, E425, and E525 series are equipped with independent graphics cards,
Update the latest BIOS.To solve the failure of F7 and F8.
After downloading the package, turn off all running programs, and ensure there is sufficient power supply, plug in the battery, and connect to the power. After confirming that the update is correct, run the downloaded upgrade program, decompress the package in the default path, and then run it. The fan will go crazy during the update process, which is normal. After the update is complete, you will be prompted to restart. After restarting the desktop, right-click the desktop, select "Display Card properties", and click "Switch display card mode ",
Select 2nd items and then click "application". You will be asked if you are sure of an English prompt for this setting and click "Change". The screen will flash during this process, after the message is stopped, the system successfully switches to the dedicated host,
Finally, right-click the desktop and click "configure interchangeable display card" to view the effect:
If the current graphics processing unit is "high-performance GPU", it indicates that it has been successfully switched to the dedicated display. When only the exclusive display is used, the system memory usage is much smaller. The independent video card has its own display memory, which is no longer shared with the system memory.
After these settings, the memory usage at the startup will return to about 45%, and the minimum can be 35%-50%. If you don't open a lot of large software, it can basically be no more than 60%.
The speed will also be greatly improved.
