Deep sleep won't let my keyboard work but i can use my mouse. and the strage thing is when i plug the mouse and keyboard none of them work. And some times when i plug in my keyboard my pc die.

Change the keyboard. See if this will wake the laptop. Why not use the internal keyboard?

Hold down the power button on the computer for 10 seconds. IT wil turn off. Then restart it. See what it says.

HP Pavilion Slimline S3400f Desktop.
dont worry ALL PC end up like this,, all do.. sooner or later..
NO OS stated, XP"? never post without OS stated, or answer get 10x more harder, See? make it easy for the helper and get more help.....
no Monitor stated. (maker, CRT, LCD what?)
The monitor is not fibbing to you BTW, the PC did go dead or to sleep. seems its monitor monitor of some kind with DVI.

if the monitor works on other PCs then the monitor is not bad.
i Bet it works (old ones 2002, have a hidden deep internal sleep mode. and is not yours IM sure now) DVI IS THE ONLY CLUE THERE.
So PC is dead. this PC came with only VISTA new,
is it still VISTA?????????
HP has support on it still
here (carbon dated by me 2008, IIRC)
https://support.hp.com/us-en/drivers/selfservice/hp-pavilion-slimline-s3400-desktop-pc-series/3688715/model/3688723

this year,? get all those files and books there backed up
when HP support ends after 10 year rule, (be savvy?)


what keyboard USB or wireless keyboard mouse
use wired USB keyboards if wireless the battery is dead. easy no?

now in VISTA, go to Control panel, click power
turn off all sleep modes and all hibernate modes
the turn off screen savers, if turned on , disktop . RC right click
in display settings or personalize, turn off , need login to come out of sleep or screen saver.
try a real keyboard, that has USB cable yet? be first thing to do.
always keep a real keyboard, handy,,,
batteries fail. in all wireless devices like this (inside them)

luck you desktops have lies DIM fails. there are many.

Hi,

Have you tried connecting your keyboard to other computer? If that works, the problem may be at your computer.

Please don't hesitate to contact me again.

thanks.

Try downloading new drivers for your keyboard. Go to the logic tech website and get plug in the model number of your keyboard under the product support keyboard driver section. Reboot your computer and it should work.

Hi I have exactly the same problem. Did you find a solution?
Please email me [email protected]

This should solve your issue from keyboard not responding..

I'm having the same problem. Mouse works great but the keyboard doesn't. I've uninstalled and reinstalled the software at least twice via remote desktop- done a hard reboot on the hardware (it's a Logitec wireless keyboard) - I've even tried installing it on another computer and the keyboard and mouse both work great! I just can't get it to work on my computer. The curious thing is that the side buttons (like sleep work) but it won't Ctrl Alt Del so I can login - what am I doing wrong? Are there settings that need to be changed?
