How to replace the keybord on an advent 9517 laptop

Advent laptops are manufactured by DSG International, which owns the names to other name-brand computers such as Acer and Hewlett-Packard.
The Advent laptop keyboard has integrated mouse touch-pad functions that allow you to move the mouse around the screen with your fingers.
Function keys at the top of the board contain alternate ways to exit and enter software applications.

Function Keys
The Advent laptop keyboards function keys are "hot keys" that act as shortcuts to applications and functions on the computer. The function keys sometimes don't work and won't carry out the function assigned to the key. This problem is considered a hardware malfunction, and the solution is to replace the keyboard or use a universal serial bus (USB) keyboard for the laptop. b> Malfunctioning Keys b> Advent keyboards are made of thin plastic. Striking the keys too hard will cause the keys to break or stick awkwardly in the housing unit that supports the keyboard. When these keys get stuck in the housing unit, a pin tool can easily set the keys back on track. If there are too many keys that get stuck or broken, you can purchase a replacement Advent keyboard and have it installed. b> Mouse Problems b> The mouse is located at the bottom of the Advent keyboard but is connected to the keyboard data strip that sends information through the keyboard unit to move the mouse on the screen. If the mouse malfunctions, check the connector under the keyboard to see if it is loose. A loose connector can cause the mouse or other keys not to function on the laptop. b> Electrical Shortage b> An electrical shortage can cause an Advent keyboard not to work properly. A shortage is when the main board of the laptop is not getting the voltage needed to efficiently operate the computer. When this happens, certain devices underperform or become inoperable. Check to see if your power supply is extremely hot or if your system heats up around the keyboard. If so, replace the electrical adapter. b> Wire Damage From Keystrokes b> The wire that is responsible for the liquid crystal display (LCD) on the Advent laptop extends from under the middle of the keyboard to the LCD display unit. This wire is unprotected and can be damaged from striking the keys over the wire. When this happens, the display will not show the correct colors or the screen will go black. To eliminate this problem, purchase a keyboard cover that fits the keys to relieve the pressure between the keyboard and video cable. b> Keyboard Drivers b> Problems have been reported with upgrades from Windows Vista to Windows 7. Windows 7 will not recognize the system drivers that operate the Advent keyboard. To get the keyboard to work, you must load the old drivers in Windows 7 Safe mode, which is used anytime there is a hardware or software discrepancy. Advent keyboard drivers can be loaded from the original restore CD, which is included with the system at the time of purchase. Series/9517 (Black)/KBAD3

Shortcuts have locked up on my pc

Conflicting Extensions

Add-ons, also called plug-ins or extensions, are mini-applications that attach themselves to independent software and add extra capabilities to the program.

Extensions can change a browser's interface, alter the behavior of existing operations, add new functions or install in-browser support for programs like Shockwave Flash or Adobe Reader.

Because these extensions make changes to the overall operation of a browser, they can also affect the shortcut keys.

Most browsers offer an option to run the application with add-ons disabled; if the shortcut keys work when extensions are turned off, one of the add-ons is at fault.

Key Reassignments

Programs like MapKeyboard, SharpKeys and KeyTweak can reassign the functions of each key on the laptop keyboard.

If the computer is running a non standard keyboard layout, certain keys might not behave or respond normally.

For example, if the "Ctrl" key has been disabled or is set to work like "Shift," shortcut keys won't work as expected because the keyboard is no longer using its default mapping.

If the keyboard layout has been changed in the Dell laptop, the registry will contain a Scancode Map entry in

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout or the language bar will show a keyboard language different from the default ("English (United States)," or "EN," for Dell laptops purchased in the U.S.).

Virus Infection

Malicious software can affect the function of peripheral components like the keyboard and mouse.

If the keyboard is exhibiting strange behavior for example, if certain keys do not respond or if keys output unexpected letters a virus is most likely the cause.

Running an anti malware software from within Safe Mode accessed by pressing "F8" on the Dell logo screen should remove any viruses interfering with keyboard response.

Browser Software

Upgrading or downgrading a browser on the PC can affect the Internet shortcut keys associated with that program, especially if the version removes a function that was once associated with a particular keyboard combination.

Alternatively, if you've switched to another browser, you might find that certain shortcuts that worked in the previous browser don't work in the new one.

For example, while "Shift-F10" opens a context menu in Internet Explorer, the same keyboard combination does nothing in Mozilla Firefox.

Hope this helps.

It could either be a software problem or a hardware related issue;
1. check the keyboard workability in safe mode, if it does not work in safe mode, you would need to get it replaced.However, if it works, then that would mean that it is a software issue in which case you would need to either try system restore or operating system reinstallation.
Also, you have not mentioned which key(s) are non-functional. if it is just number keys then you would need to ensure that the num lock key is on (by just pressing it once).

My whole keyboard not responding

Since this is a laptop, you might be having some trouble with the motherboard this time. Test the keyboard functionality first by doing F12 on the Dell splash screen. Then select boot to utility partition if you have the option. Select custom test among 4 diagnostic options. If the keyboard fails on the test, then you need to call up dell to have the motherboard replaced since the keyboard has been replaced.
