Click the link for the PC Operating System (like Windows XP).
Try to find the BIOS update listed under the heading, BIOS , BIOS- System , or RomPaq. NOTE: The term "Rompaq" refers to BIOS updates for Compaq Presario PCs prior to 2002.
If a BIOS update is not listed, HP does not have a BIOS update posted for your PC at this time.
If there are several BIOS updates available for different motherboard names, you need to find out what motherboard is installed in your PC. This can be done by turning off the power to the PC, removing the side panel, and reading the name that is printed on the motherboard. The name of your motherboard should match or be similar to the name of the download link.
If a BIOS update is listed, proceed to the next step to download and install the BIOS update.
Step 3: Download and install the BIOS update
Click the download link. The instructions for downloading and installing BIOS updates vary.
For most PCs with Windows XP, download the file, open it and follow the on-screen instructions.
For many PCs before Windows XP, save the downloaded file to the hard drive, insert a formatted disk, open the downloaded file to copy the BIOS files to the disk, and then restart the computer with the disk still in the drive.
The instructions on the download page may be different so carefully read and follow the instructions on the download page and in the installation setup screens.
If a 251 or CMOS Checksum error occurs after installing the BIOS update, perform the following steps:
Restart the PC and enter the BIOS screen by pressing the F1 or F10 key at the first screen.
Press the F5 key to load the default BIOS configuration.
Select YES by using the arrow keys, and then press Enter .
Press the F10 key to save the settings and exit.
Select YES by using the arrow keys, and then press Enter . When the BIOS update is complete, the new BIOS revision number is updated on the Main BIOS screen.

there is no such thing as a free download of a microsoft product
you may get a disc for win 8 but to make it work you will have to buy the licence to register it and that is as costly as buying the disc to start with
the only free operating systems are LINUX--ubantu and it is far better than microsoft when you get the hang of uing it
Since October 31, 2013, Windows 7 is no longer available in retail (except for the Professional edition preinstalled):
Windows 7 Starter
Windows 7 Starter is the edition of Windows 7 that contains the fewest features. It is only available in a 32-bit version and does not include the Windows Aero theme. The desktop wallpaper and visual styles (Windows 7 Basic) are not user-changeable. Microsoft originally intended to restrict users of this edition to running three simultaneous applications but this limitation was dropped.This edition was available pre-installed on computers, especially netbooks, through system integrators or computer manufacturers using OEM licenses.
Windows 7 Home Basic
Windows 7 Home Basic was available in "emerging markets", in 141 different countries. Some Windows Aero options are excluded along with several new features. Home Basic, along with other editions sold in emerging markets, include geographical activation restriction, which requires users to activate Windows within a certain region or country.
Windows 7 Home Premium
This edition contains features aimed at the home market segment, such as Windows Media Center, Windows Aero and multi-touch support.
Windows 7 Professional
This edition is targeted towards enthusiasts and small-business users. It includes all the features of Windows 7 Home Premium, and adds the ability to participate in a Windows Server domain. Additional features include support for up to 192 GB of Random-access memory (increased from 16 GB), operating as a Remote Desktop server, location aware printing, backup to a network location, Encrypting File System, Presentation Mode, Software Restriction Policies (but not the extra management features of AppLocker) and Windows XP Mode.
Windows 7 Enterprise
This edition targeted the enterprise segment of the market and was sold through volume licensing to companies which have a Software Assurance contract with Microsoft. Additional features include support for Multilingual User Interface(MUI) packages, BitLocker Drive Encryption, and UNIXapplication support. Not available through retail or OEMchannels, this edition is distributed through Microsoft Software Assurance (SA). As a result it includes several SA-only benefits, including a license allowing the operating of diskless nodes (diskless PCs) and activation via VLK.
Windows 7 Ultimate
Windows 7 Ultimate contains the same features as Windows 7 Enterprise, but unlike the Enterprise edition, it was available to home users on an individual license basis. Windows 7 Home Premium and Windows 7 Professional users are able to upgrade to Windows 7 Ultimate for a fee using Windows Anytime Upgrade if they wish to do so. Unlike Windows Vista Ultimate, the Windows 7 Ultimate edition does not include the Windows Ultimate Extras feature or any exclusive features as Microsoft had stated.
All editions will receive Mainstream Support (new features and bug fixes) until January 2015 and Extended Support (security updates) until January 2020.

For Acep Aspire 504x model systems that have Bluetooth built in, there is an on/off switch located in the front of the system.
For systems with bluetooth built in there will be two buttons next to each other just left of the mic and headphone ports.
The left of the 2 buttons is the bluetooth switch and the right of the 2 buttons is for 802.11 wireless.
If you only have 1 button then you do not have bluetooth built-in. You can also check to see if bluetooth is included by looking at the bottom, if Bluetooth is installed there will be a white FCC lebel with the name Bluetooth written on it.
