Keyboard error in windows

I also tried with external keyboard and it does not work.

And the mouse does not work either.

Run  the diagnostics. Select the options to test an indivudual component. And test the mouse, both the Trackpoint and the Synaptics. Then run the test for all the keyboard keys.

If you can't do this from the onboard diagnostics then download the CD ISO image from the Dell site, write it to a good quality CD-R and then boot the CD.

Is all ok?

I can not get it to fail in testing, so everything is ok there.:emotion-40:

Well if the diags say the keyboard and the trackpoint are ok. And also that the Synaptics is ok. Then the issue lies with Windows.

Use F2 on power on to get to the bios setup. Navigate to maintenance and select the option to load default values. Then save and exit. And this might be obvious but eject your laptop from any docking station first.

That is a long shot, if it does not work then you need to get to device manager in Windows and delete the keyboard and mouse. And restart; upon restart the keyboard should be re-discovered and also the mouse. At least the basic Microsoft PS2 mouse as distinct from the Synaptics version. Then re-install the Synaptics drivers.

How to do this with no working  keyboard and mouse is a mystery? So I suggest you boot the XP CD and try to launch the recovery console. Seem to me that the registry might be corrupt or the hard drive is failing. So try to run chkdsk /R on the C: drive from the recovery console prompt. That will take several hours depending on disk size.

If that finds nothing you might be able to use the recovery console to revert back to a restore point prior to when the problem occured.

You could also remove the hard drive and attach it to another working computer, via a SATA to USB adapter and run chkdsk /R from there. And use the opportunity to back  up everyrhing on the hard drive.

I say that because you may end up having to do a clean install. So I would get a backup before going any further.

I would just add that assuming your D630 has 2GB or more of ram then I would seriously consider upgrading to Windows 7. Windows 7 64 bit (or 32 bit) runs very well on these laptops, even with 2GB of ram. 4GB is a bit better but is more icing than cake. And if you want a bigger hard drive then get a Hitachi, Seagate or Western Digital 7200 rpm  9.5mm high SATA with 16Mb cache.

In some repects these systems are faster, or at least as fast for most purposes, than  some newer systems.

So the hard drive appears ok. However chkdsk corrected some file system corruption. So I suspect your registry files might have been damaged. When you re-instate the drive do the keyboard and mouse work in Windows safe mode? Can you delete the keyboard from the system and let it re-discover?

If not you will have to boot into the recovery console from the XP CD and see can you revert to a date prior to when the problem first appeared, using a restore point.

Although there are other methods of recovery, thay are quite complicated and beyond the scope of this forum. Sometimes the quickest and easiest thing to do is a clean install of Windows. I hope you have a backup.

For info I have taken a backup.

It does not work after it has run chkdsk

I have found out that I can access it via RDC.

I can not get it to install the driver, although it writes that it has installed drivers.

Did you reset your bios to default values? If not, then tap the F2 key when you see the Dell logo at power-on. Enter the bios and find the option to load default values. Then save and exit. The system will spend longer than normal on the Dell screen when it restarts.

(I note that you have an Alps driver for the mouse. Surely the driver is Synaptics? Where did the Alps driver come from?)

When the system restarts press tap the F8 key and get into safe mode. If the mouse and keyboard still do not work, then restart and do what ever you did before to get in. Use device manager to delete the Alps mouse driver and restart. If your mouse is rediscovered as a standard Microsoft mouse then do the same thing for the keyboard.

I mean delete or uninstall  the device as distinct from reinstalling the driver.

If that does not work then use the device manager to update the driver and then manually select standard Microsoft mouse. And restart.

If all that does not work then you either have an as yet unidentified hardware issue that is interfering with the mouse and keyboard, as diags say these are ok. Or your system registry is corrupted.

Overall I think you might be best off with a clean install of XP. Otherwise you could spend days trying to track this down. Make sure you have any Microsoft Office install keys or install keys for any other propriety software.

Bear in mind my prior comments about these laptops and Windows 7. If I had to do a re-install I would install Windows 7 Professional 64 bit. Latitude D630s run this quite well so it is worth the investment.

Update to my post above. I have extracted the files from the Dell XP mouse driver and they are indeed Alps.

Everthing else still stands. Try to delete or unstall the Alps driver. And get the generic Microsoft installed. To see does that fix the issue.
