Updating the computer system or changing the system is very troublesome, but some software can only run under that system. Such reasons force some people to spend a lot of effort to change systems. Computer system replacement is also a technical matter. Many people have to spend money to find other people to change the system. The following is a summary of the process of installing XP on Lenovo U150.
1. Make a factory backup of Window 7
Follow the recovery software prompts provided by the system to back up the factory configuration of the notebook to a DVD disc. . The U150 notebook itself does not come with an optical drive. You can find a USB optical drive box and a desktop optical drive to form an external optical drive. This step is very simple, just follow the prompts. Backup requires two 4.7GB DVD discs.
2. Install XP
There are many ways to install XP on the U150 notebook without a CD-ROM drive. Because I have an external DVD drive as mentioned above, I just use the original method through the CD-ROM. Install XP. Before installation, enter the BIOS and adjust the hard disk mode from AHCI to IDE. This is very important. If you do not adjust it, you will get a blue screen when installing an XP system without integrated patches. It is also very important to turn off the built-in wireless network card in the Bios. If it is not turned off, it will easily cause a blue screen crash during the XP installation process, especially during the hardware detection and driver installation stages. Adjust the boot sequence to USB-CDROM boot.
After the above adjustments, installing XP through the CD-ROM drive will be very smooth, all the way to the desktop. Everyone should pay attention to partition processing when installing XP. When dual systems are not needed, you can directly start the notebook with the XP installation disk. When selecting a partition, directly delete the first two NTFS partitions of the hard disk (that is, the original Windows 7 system disk) , then create a primary partition and install XP directly on the newly created partition. Many netizens are used to Ghost installation. I don't recommend doing that. It feels like it saves trouble, but inexplicable problems will appear during subsequent use and will be more troublesome, so it is best to use the original clean XP installation.
3. Install the driver
This is the most critical thing. Many friends have problems when installing drivers. Everyone will succeed if you follow me.
1. The general method of installing drivers is to install the bottom layer first and then the peripheral devices. Statistics of the programs downloaded from Lenovo's official website cover almost all aspects, but they are still incomplete, as will be discussed below. First install the motherboard driver U150_XP_Chipset.exe and restart after completion.
2. Install the south bridge patch U150_XP_ICH9M.exe and remember the directory location of the decompression. Restart the computer, enter Bios, and change the hard disk mode from IDE to normal AHCI. After startup, the system will discover new hardware. When installing the driver, set the driver search directory to the unzipped directory. After the driver installation is completed, restart the notebook.
3. Install the wired network card driver U150_XP_Lan.exe. Why install the network card driver in front? This is all the fault of the evil Microsoft. The subsequent sound card driver installation must be supported by MS.NET FRAMEWORK 3.5. During the installation process of MS.NET FRAMEWORK 3.5, there are about 20 MB of data that must be connected to Microsoft's server online to complete the installation, so the wired network card driver can only be installed in advance.
4. Install Microsoft’s HD Audio patch, which is usually the UAA.exe file. After the installation is complete, follow the prompts to restart the system. Two unknown HD Audio devices will appear.
5. Don’t rush to install the sound card driver yet. First install Windows Installer 3.1, and then install the MS.NET FRAMEWORK 3.5 suite. Let me mention here that when installing the MS.NET FRAMEWORK 3.5 suite, you must connect to Microsoft's server to download data, otherwise problems will occur.of. These two software are used to prepare the sound card driver. After the above is installed, you can install the sound card driver Audio.exe, which is very smooth. You can also use the IN2AUD04WW1.exe driver for the sound card driver. IN2AUD04WW1.exe is obtained from Lenovo's Taiwan website. Some netizens say it is better. I installed both without any problems. As for which driver to use, it is up to you.
6. After restarting the laptop, install the graphics card driver. Note that no matter whether your laptop has a discrete graphics card or an integrated graphics card, Intel or Nvidia or ATI, as long as the laptop has an HDMI interface, when installing the graphics card driver, The sound card driver must be installed. After the driver is installed successfully, unknown HD Audio devices will no longer appear in the device manager. Everyone should pay attention. This is why the sound card is installed before the graphics card.
7. Restart the notebook, enter Bios, and turn on the unlimited network card. After entering the system, install the official Broadcom802.11_Wlan_XP.exe driver provided by Lenovo. If the driver is still not found, you can install it manually in the hardware manager. Because the previous wired network card has been installed, the device name of the wireless network card is easy to distinguish. I found the driver for my U150 by myself, so I didn’t have to worry too much. If you still need Boardcom's management software, you can go to Boardcom's official website to download the full version of the driver and install it.
8. At this point, you can install Bluetooth, card reader, camera, touchpad driver in the usual order, and finally install the power management software 150_XP_PM.exe. The drivers here are all downloaded from the official website.
9. There are also some software provided by Lenovo, which you can install according to the situation. After the above troubles, your laptop can run XP perfectly.

During the process of replacing the system, many dialog boxes will pop up to instruct the next step. Sometimes, the wrong ones are used accidentally, causing the stored data, files, Pictures, etc. are lost, or all previous efforts are wasted during the system replacement process, so the problems that may occur during the installation process are also listed above. I hope the system installation is successful. The above is the relevant content about installing XP on Lenovo u150. I hope it can be helpful to everyone!
