Question about HP Compaq Presario SR2150NX PC Desktop

1 Answer

Busted registry I guess I fiddled with my Windows registry one too many times. Mouse and keyboard don't work at all. Not even in safe-mode. Can a new registry be loaded on my disk? I don't care if 90% of my previously-installed apps don't work. I hope to re-install one or two apps so I can bring closure to this thing. I don't want a "restore", because there's so much stuff on my disk that I don't want wiped out. Plan B is to try to guess folder-names where all my stuff is and have someone pull off what I might want.

I have a Dell 2350 PC and none of the usb or other ports work except the monitor


Make sure the batteries are inserted correctly and have charge if applicable
usually located on the underside of the mouse there might be small plastic sticker with a phillips head screw under it rub your fingernail over the top to see if it has a screw
or make sure the usb device is properly inserted for wireless
the usb or Ps2 connection are secure with a dust free connection

or it might be the usb for wireless mouse or lead connecting to the usb port or even a faulty mouse
if this does not fix the problem
Restart you computer tap the f8 key repeatedly to enter safe mode where the only things working will be your keyboard and mouse allowing you an attempt to repair your computer
If done properly the user should get to a screen similar to the below screen.
Select the option for Safe mode command prompt only
Windows Advanced Options Menu
Please select an option:
Safe Mode
Safe Mode with Networking
Safe Mode with Command Prompt
Enable Boot Logging
Enable VGA mode
Last Known Good Configuration (your most recent settings that worked)
Directory Services Restore Mode (Windows domain controllers only)
Debugging Mode
Start Windows Normally
Reboot
Return to OS Choices Menu
Use the up and down arrow keys to move the highlight to your choice.
select safe mode
click start control panel administrative tools computer management device manager scroll to mice and other pointing devices you might see a yellow exclamation mark ! or question mark ? or a red x
right click you will need to update the driver
Click start control panel mouse you should see 4 tabs buttons pointers pointer options and hardware under hardware you have options to troubleshoot also you can select properties under driver you will have options to update driver rollback driver or uninstall also
I have found that the best way to adjust your mouse settings is to create a control panel in your bottom toolbar scroll to the bottom of your screen right click you will see an array of options select the toolbar option then select desktop
then you will see the desktop in the bottom toolbar select the 2 arrows >> then all control panel items then select mouse this is in WINDOWS 7
in XP you will have to select the new toolbar option once you have that a browse option select my computer then control panel then a control panel option will be in the bottom toolbar
Click start control panel keyboard hardware make sure you have the right keyboard selected
or you might have uninstall the keyboard then restart your computer then reinstall it and its drivers
click start control panel administrive tools computer management device manager scroll to keyboard you might see a yellow question /exclamation mark ? ! or a red X right click update driver

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.

Hi,
If you are using PS2 port, you can try using usb type keyboard and mouse just to check I/O system.

You can also boot to "Safe Mode" by pressing F8, F10, F2..depending on the brand of pc you are using. If the mouse and keyboard work in Safe Mode, then you are having a software problem. In this case, you can try either of the following options.
- scan for virus, malware or spyware
- obtain windows updates
- reinstall the operating system
- try to do registry editing (it is advisable to back up everything before performing this step, just reinstall the operating system if you are not comfortable of performing this step)

I hope this helps.

Assuming the keyboard and mouse are wired/usb type, I would unplug them both, then restart the machine. Wait for windows to completely load, then plug them back in (preferably into different usb ports) then wait 60 seconds... That should resolve your issue.

I have a xp pro system. The keyboard and mouse work during BIOS. They will not work in safe mode or in windows. I have tried other keyboards and mice. None of them work. I am running eyeonet dvr software....


somewhere in the bios you might have a setting for lecgacy or usb 1 or usb 2. just select a different option and try again. this sounds like a common problem but only the other way around. usually if the usb setting is wrong a keyboard doesnt work in bios but works in windows.

Dell xps 400 keyboard and mouse not working, but the keyboard does work in when in service mode


If it works in service mode, then it is not a hardware problem. Boot Windows in "Safe Mode" using the F5 Key as it is Booting to Windows. That should make it re-discover the KB and Mouse. Make sure the KB and Mouse are pluged into the right ports. Mouse Green and KB Purple

PLEASE HELP.. KEYBOARD AND MOUSE ARE COMPLETELY DEAD


If you can bott the computer normally and don't have to type a password in, then go the control panel and then choose device manager. Scroll down to the mouse and keyboard plus signs and right click on the mouse and keyboard one at a time and select uninstall. When the original mouse and keyboard have been uninstalled, reboot the computer. When Windows starts back up it will be forced to search for the new hardware and will install the drivers for it. If it wants to search for new ones allow it. If you have to type a password, you will have to go and get a usb keyboard that works off one of the usb ports. If this doesn't work, reboot the computer with the Vista disc in. Click any button to boot from the cd. When the windows files load and windows starts, choose repair, choose the windows installation and let windows search for problems and see if it can fix them. If all fails, go to system restore and back the computer up a few days and let system restore fix the problem by taking you back in time a few.
