Many users bought the laptop HP OmniBook 6000-F2044W Laptop Battery, the often pre-installed operating system is not satisfied, like the Windows Vista downgraded to Windows XP, or Windows XP upgrade to Windows Vista. The notebook has some specificity, the user changes the operating system, is easy to encounter some problems, only to solve these problems can be successfully used after the change of the operating system. Here the author to change the notebook operating system for some of the key points to note to explain.

First, refresh BIOS5
Many brands of notebook HP OmniBook XE3 Series Laptop Battery factory pre-installed Windows Vista, by default does not support Windows XP, Windows XP if the user directly modified, they would have many problems, such as the wireless card can not search for wireless networks , can not shut down properly, etc. Some laptops can not even directly install Windows XP.

This is mainly caused by the motherboard BIOS is not compatible with the problem. We can update BIOS to solve the problems.
HP DV272X Series notebook to an example, the model pre-installed Windows Vista, BIOS to F.25 version, you must brush back to the F.13 version, BIOS can be successfully used Windows XP.
 
Log in HP HP OmniBook XE2-DC-F2065KG Laptop Battery official website, download the version F.13. Before the BIOS update is recommended that you install the battery, then connect the power adapter, so as to avoid unexpected power outages. Everything is ready, log on Windows Vista, run the F.13 version, follow the prompts to enter the refresh screen, click "YES" button to refresh the BIOS, about 1 minute after the laptop shut down automatically. After a successful BIOS update, laptop to install Windows XP.
Some pre-installed Windows Vista laptop while supporting Windows XP, but users install Windows XP Shique will find tips laptop can not find the hard drive device.

This is the Windows XP installation disk is not integrated SATA drive causing problems. The workaround is to enter the BIOS settings , in the "Advanced" in the "IDE Configuration" under the "SATA Native Mode" set to "Compatible" or "Disable", so that SATA controller into compatibility mode. In other words, through the above, disable the SATA native mode, the hard disk to IDE mode, install Windows XP does not detect when the SATA controller, users can install Windows XP.

Due to the SATA mode to compatibility mode, the drive requires a detection process of adaptation, so when you install Windows XP may prompt a denial format the hard drive, then simply press the Enter key and repeat 2 or 3 times, can continue to install Windows XP.

Note that, in the installed Windows XP, to re-enter the BIOS settings, the SATA mode turned on (set to "Enable"), then go to Windows XP, manually install the SATA drivers.

Third, the failure to resolve driver compatibility
Installed operating system, due to the operating system built-in drive is compatible with possible failure, the user may find in a lot of problems, such as Wan game black screen, the network frequently Zhongduan so, then you need to install the hardware specific driver to solve the problem .
Usually we can go to the manufacturer's website to download the relevant drivers. If the official website does not provide specific drivers, then we can install the chipset manufacturers to develop a generic driver, such as Centrino-based notebooks to change the operating system, you can install the Intel Chipset Device Software common motherboard chipset drivers (Figure 3). So, the graphics cards, sound cards, network cards and other related can be installed all drivers.

It should be noted that some models in the modified operating system, which may cause the failure to install the driver, such as installation of Intel wireless network card driver is not compatible when prompted, this time as long as the mandatory install.
Also, sometimes even the hardware drivers installed, you can still be some problems, such as Windows Vista will be reduced to Windows XP, sound card and microphone are not working, this is because Windows XP does not recognize the HD bus, then you need to install Microsoft offers the HD Audio patch.
Therefore, if we discovered that the driver does not conflict, but the laptop can not use certain features of the case, Microsoft or the manufacturer may wish to find the corresponding patch official website
Fourth, the upgrade configuration

Many pre-installed Windows XP, Windows Vista notebook HP OmniBook XE2-DC-F2028WT Laptop Battery converted, run very slowly, or even a fake crash, play game card machine failure, but the driver 又 no conflict. This is due to the problems caused by low performance of the hardware.
To the normal operation of Windows Vista Premium, requires the configuration of laptops over with at least 1GHz processor, 1GB of memory above, 128MB or more memory capacity, 40GB hard disk capacity above. Many older laptops only comes standard with 256MB of memory , 20GB hard drive, to modify Windows Vista, I suggest at least the memory and hard drive upgrades, and choose to install Windows Vista Basic Edition.
If you have to install Windows Vista Premium, then, to ensure speed, proposes to reduce the level of Windows Vista's performance, and shielding the operating system in a variety of special features and effects, such as adjusting the window interface operating system as a "performance" mode, so 30% can improve the speed, and cancel the defrag, turn off Windows Defender, turn off System Restore function modules, not only can reduce the frequency of hard to read, you can also save hard disk storage space, so that more resources allocated to the application software .
Fifth, to retain features

Brand notebooks HP OmniBook 2100-F1584WT Laptop Battery have built a variety of features, such as a key recovery, fingerprint recognition, face recognition, battery energy, etc., but in the modified operating system, these features often ineffective.
How to keep these functions? First we talk about how to keep a key recovery. If you want a new operating system can also use a key recovery feature, then install the operating system needs to re-partition the hard drive before, and that has two or more partitions. After installing the operating system to manufacturers website to download a key recovery program, then the new operating system to install a key recovery program can get a key to recovery.
Note that most laptops have multiple partitions, the first of a partition for system files , and the last partition was hidden partition, system recovery files are retained in the hidden partition. So the first partition and hidden partition can not be formatted.
The same way, you can also refer to a key anti-virus, a key audio, video, fingerprint identification, battery and energy saving functions.

If the modified operating system, use the function fails, the proposed closure of these modules into the BIOS (such as TMP chip) for better compatibility
