Dell Inspiron 7520 :: Mouse Pad / Keypad And Keypad Backlight Not Working
Apr 1, 2013
I have recently purchased Dell inspiron 15R Special Edition 7720 laptop.
1) Backlight not working, not sure whether I've this service or not because I can't see anything in Windows Mobility Centre
2) Keyboard and mouse pad works in safe mode but not in normal mode.
When I tried to remove Cypress trackpad, only mouse pad worked, not keyboard. Now only keyboard is working after Cypress trackpad reinstallation? I've tried to resolve it many times using drivers updater but failed all the time.

The touchpad on my Studio 1749 is erratic - it zooms in and out or scrolls when all I am doing is moving the cursor around the screen. I have updated drivers recently and run Dell Detect.

How to make my keyboard entries match the keypad layout? I have tried several English keyboard layouts available from the installed files but none of them exactly match my layout. For instance one layout (English International) require a space after every " or ' before the character will appear. I can understand this as it allows for certain special characters related to other languages. If I change to plain English then the key comes out as #. I have downloaded Microsoft's keyboard mapping application but it does not seem to work in Win8. I don't get any layout diagrams when I load a keyboard file. I am pretty sure it is the layout file because an external keyboard gives the exact same characters as the Dell factory installed kbd. I know there is commercial mapping software available but I don't want to buy it and find it won't work just as Microsoft's doesn't.

I might have seen the numeric keypad keys work once since getting this machine, but now can't get the keys to produce numbers. Some of the keys initiate other actions not associated with numeric data entry.
I tried removing the wireless dongle for my Microsoft wireless mouse but no improvement -- I simply swapped this MS mouse from my old W510 without doing any formal install.
This doesn't appear to be a hardware problem since the keypad keys have some effect -- just not the intended effect.

My dell inspiron 3521 keypad is not working i have updated all the software and system update is on.
i haven't installed any software, third party application or anything else like that which interferes with my keypad functioning.
I tried to update the drivers for the keyboard from device manager but it showed that the driver is already up to date.
I also checked the ribbon that connected to the keypad with the system hardware and there is no problem in the connection there also.

I bought Dell Inspiron 15R SE (7520) like a week back. The laptop is just fantastic and it's working pretty well as intened. Today i just found out that this laptop has a KEYBOARD BACKLIGHT. I turned it on from the Windows Mobility Center, but it's not working at all, do i need to install any drivers for it? I work mostly during night time and a backlight would really good...

After a short period of use my xps13 first edition ceases to accept keypad inputs. I just get a ping and nothing happens. Called premium tech support and not solved. Ticket still open and machine still useless. Pity as after having had so many dell products, what should have the "wow" factor has the "whoops" factor. I have resorted to an external keyboard, but that is hardly the elegant nor portable solution for which one had hoped.

On my acer 5920g, I've installed XP and all drivers without problems, but my sensor keypad does not work like media buttons, but just like single click on touch pad. Which driver I've miss? I've also installed lounch manager driver and nothing happens.

When Windows is finished loading my touch and key pad seems to turn off. My device manager does not indicate any problems with either. In safe mode everything works fine. Since I did not have anything valuable stored I used the acer recovery and had it reinstall Windows fresh. After that, it seems to work fine with no problems.
Auto updates starting downloading and after updates are installed I have the same problem again. I have done this procedure a few times. I have also install AVG Anit virus and thought maybe thats what was doing, so this last time I did not re install the anti virus.

I was just wondering if there was a numerical keypad that could be slotted into the utrabay port for the t400? I find the numerical keyboard in place of the letters very difficult to use and I'd imagine that using a numpad plugged in via USB would be quite annoying if I was on public transport.

new screen/inverter/ backlight installed. NEW screen still black, but visible with flashlight. Went ahead and got ANOTHER inverter off eBay and tried that - screen still black. Haven't ever replaced a backlight, and the operation looks delicate (and expensive to HAVE done) ...

I have a Dell Inspiron 7000 series and 2 days ago Windows installed a critical update which stopped my keyboard and mouse working, I have had to do a system restore to get it working again but with it being a critical update I'm assuming I will need it.

At this point I've already replaced the inverter, screen, and LCD cable. I'm guessing the problem has to be with the motherboard.

my backlight and touchpad are not working since i replaced my DV3000's motherboard with one meant for a DV3500 (wrongly listed as DV3000). I think that it has something to do with the lid sensor.

I bought an Aspire R13 recently and noticed the spacebar wasn't backlit. Is that normal?
Also, am I the only one who is able to hear the backlight's high pitched PWM when it's fully on?
