ThinkPad Edge E420 slow bootup

My thinkpad E420 (1141CTO) takes about 1min and 20 secs to boot up and another 20-30secs the desktop will show up after I type my password, and it slowed down when I accidentally un-install the rapidboot. I reinstalled the rapidboot version 1.10 by downloading in the Lenovo site and upgraded the RAM into 8gb but is still the same.

If the system now takes longer to start up than when it was new, it may be that other applications have been installed and are being loaded as Windows starts up.  After checking power manager settings to ensure maximum performance good place to start is the with msconfig tool to investigate the processes which are being loaded as the system boots up. 


1) Check Power Manager settings:


If you are using Power Manager, choose Maximum Performance plan. If not, choose High Performance plan. Power plans affects boot performance. Choosing Balance or Power Saver, or other plan would prevent the system to have the most optimum / fastest boot.


2) Using MSCONFIG to evaluate which processes are being loaded at boot


Click Start on the taskbar, type msconfig on the search bar and press Enter

Go to Startup tab 
Disable / Uncheck most, except:
Your antivirus software / Security Suites
ThinkPad Power Manager (If you installed it)
ThinkVantage AutoLock (You can uncheck if you do not need auto-locking security, etc.)
ThinkVantage Active Protection System

Microsoft Windows Operating System (if available)

Intel(R) Common User Interface (You may need if you uses Intel Anti-Theft Technology with subscription with Computrace or other)


Doing this should reduce the amount of application tray, loader, etc. It will  reduce the memory usage and allows you to startup your computer faster.


Optimizing CPU utilization


In msconfig, under Boot Tab, go to advanced option and check Number of processors and select the highest number.

Although Microsoft said by default, the system boots from all cores / threads, this tweak is able to cut down most of systems / VM boot time by a fraction. This helps especially if you have heavy background tasks. 

3)  Disable Services that you probably won't need
Download the Safe script for your version of Windows 7 and double-click, add to registry
If there's any problem or if you want to reverse the process, you could just download the Default script and add to registry, it would go back to default.

This link shows what services are modified or remain the same, etc. 


Disable unnecessary services to reduce the amount of memory use for the system and at the same time improve system performance and security
