My computers USB ports are not giving power to devises like monitor, mouse, and key board. How do I fix this?


restart your computer repeatedly tapping the f8 key to enter safe mode while the screen is black once in safe mode where the only things working will be your keyboard and mouse allowing you to attempt to repair your computer

click start control panel administrive tools computer management device manager scroll down universal serial bus controllers you could see a yellow question / exclamation mark? ! or a red X

you will need to update/reinstall drivers

right click to reinstall drivers

if you can see your usb drive but its not working

ports(com&lpt)right click update driver if this fails to fix the problem

check the USB leads that attach to the motherboard usually red white green black make sure they are securely seated and have no dust build up on them dust will cause static and a lot of unforeseen problems for a computer and its parts

hope this helps you

One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect/ boot up a computer hard drive

Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your "((motherboard to your hard drive))" make sure they have a secure connection and are not faulty or just replace them they could be faulty
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even the electrical extensions or just replace them they could be faulty a computer needs its connections to continue its cycle and have an end so any faulty leads will end up with a computer error
try blowing out all of the dust from your keyboard using a fine air blower from an air compressor making VERY sure there is no MOISTURE in the lines.
dust causes static which causes lots of problems with a computer and its parts
click start control panel keyboard hardware then properties you should see driver details,you will have options to update driver,roll back driver,uninstall
make sure you have the driver for the keyboard before uninstalling the driver
make sure the lead is good and has a secure connection diconnect the keyboard then reconnect it then reinstall the driver(if applicable)
make sure the usb device is inserted correctly into the usb port (if applicable)
hope this helps
as for the mouse
make sure the lead has a secure seating if applicable or the usb device
make sure the battery is good (has full charge)also you might test the usb device for the mouse is inserted correctly into the usb port (if applicable)
click start control panel mouse you should see 4 tabs buttons,pointers,pointer options also hardware under hardware you can troubleshoot or
select properties under driver you will have the options to update driver,rollback driver or uninstall and under hardware you can troubleshoot the device
hope this helps

Pc wont turn on


1. Remove all USB devices such as printers, mp3 players etc etc.
2. Remove the power-cable and the battery
3. Press and hold the power button for 30 seconds
4. Put the power-cable back in but not the battery and none the USB devices.
5. Turn the computer on

Also check the condition of the USB ports if it doesnt work and the fuse. If this doesnt work then I would recommend a repair.

Dell power edge 4600 wiht 4 power supply redundant problem


thanks for your no answer !!!

Solucion: apagar servidor, cambiar la posicion de la fuente de alimentacion que marca el error ( el visor LCD indica la posicion de la fuente de alimentacion con error ) y ver si continua el problema.
Sino continua, ok
Si continua y sigue marcando la misma posicion, dos opciones, o es la tarjeta de administracion de energia ( esperemos que no ) o es un fallo del LOG de Hardware, con lo cual, bajar la herramienta DSET de Dell y borrar el LOG ( tercera opcion ) y voila, el equipo como nuevo.

No me molesto en traducirlo porque nadie se ha molestado en ayudarme, lo pongo por si le sirve a alguien.

Un saludo y menos expertos y mas trabajo !

Toshiba satelite usb problem


First check under DEVICE Manager to see if you have uninstalled drivers....if so follow the install routine (i.e. update driver)...and if you do not have the driver disk (usually it comes on the Motherboard software disk) point at Microsoft....often you can find the generic driver and it will install automatically. As for a power supply problem....probably not or you would have other strange things happening....PS...assume you have already solved the problem. I just happened to notice it and started a response before I noticed the date. Tango.
