Do you have a ps/2 keyboard/mouse? Or a usb->ps/2 adapter. I'd say boot up normally and log in with the ps/2 keyboard/mouse. Then, from device manager, right click everything under USB and such and uninstall. Then right-click your computer name in the device tree and scan for changes.

    Check in your bios for a usb enable command. Let me know if that's on/enabled.

What does the white writing say? Is it trying to boot into Safe Mode?

My keyboard in my revo rl100 doesn't work


Sounds like the battery in the keyboard is dead. Also make sure you have the wireless doggle that came with the keyboard and mouse plugged into the usb port. You might try plugging it into another port.

I'm thinking your keyboard is dead because of the battery or a virus has hijacked your keyboard.

Try booting up in Safe Mode to make sure it's not virus related. Turn the computer off, then turn it on and immediately start hitting the F8 key repeatedly until you see SAFE MODE. Select the Safe Mode option and let it boot up. Safe Mode will look different because the icons are bigger and the screen is darker, this is normal. If your keyboard works in safe mode then you might have a virus that can't function in safe mode.

My Acer L410 continually restarts. I am tryiong to start in safe mode so I can do a system restore. The keyboard works so I can select safe mode but once I reach the login on screen neither the keyboard...


I have 2 suggestions. First, try different keyboards/mice. I've had similar problems in the past with the drivers for usb peripherals not working after updates or re-installs. usually the older and more basic a mouse/keyboard is, the more likely it is to work in this situation. if you have old mouse and keyboard jacks(the round, purple or green ones that look like s-video), use them. Second, if you are running windows 7, when you get to the boot options, don't select 'safe mode', instead look at the other options below. there should be one called 'boot without driver signature enforcement' this may allow the computer to boot normally and restore keyboard function, however, it is not a solution and if it works, it indicates that you most likely have a malware problem. after you get it to boot, immediately start a scan with a reputable anti virus program (I recomend malwarebytes http://shop.malwarebytes.org/lpa/342/4/7268/free_g.html?x-at=regGcbmd ) then use the kaspersky rootkit remover.

Is this computer supporting USb functionality in installation mode? Have you tried using a PS2 Mouse and Keyboard to try and solve the issue? Some computers do not have the ability to run USB devices pre-windows so try to use a PS2 device and see if it works.

Use wired mouse and keyboard (not wireless) and change the USB port you are using to another one.

Connect them directly to the computer, do not use USB hubs.

If no joy reboot in safe mode: turn on your computer and immediately press F8 repeatedly until you get the Advanced Boot screen. Select "SAFE MODE" and press ENTER. After that, restart in normal mode.

Thank you

I have the dreaded ''blue screen of death'' but can use my safe mode for networking. help????


What operating system are you running?

Most blue screens are caused by a hardware issue. If your happy to do so, strip your PC down to the bare basics. Remove all RAM apart from one module, and PCI cards except graphics and remove mouse and keyboard.

If it now boots up OK, you know one of the things have disconnected was causing the problem! Plug each one in one by one. Also, you can try Fixing the master boot record, or booting from your Windows CD and using the repair functions

Hi sdd555,

Restart the computer after plugging the USB keyboard into a different USB port, or remove the keyboard in Device Manager and then refresh the system to work around the issue. This will cause the device to be re-enumerated and the driver will be reloaded.

Good Luck,

Mark

Inspiron 530S Power Save Mode Loop


First you need to make sure that there are no other removable devices plug on the system, like usb, external hard drives, then if that will work try to go to the bios, press f2 when you see the dell logo, and go to the system setup, go to the boot device configuration and make sure that removable device is not the first boot device, if it is the first one choose hard disk and then second boot device ad cd rom/dvd rom and then disable the 3rd boot and the fourth boot device. Make sure to save the changes. And restart the system again. Once the computer is back and running try to go to support.dell.com and check the bios, download if there is a bios update for the system.
