Dominykas, you got me thinking with this...Sounds like you are using some special gaming keyboard. Keyboards don't typically take a lot of power, but I don't know about gaming keyboards....How about check the power usage on your ports to see if perhaps your devices are using more than available. This article tells you how to check the power for your USB hubs. Or if something is shorting out you can see that also.
it's not a gaming keyboard, and, talking about not enough power or something, so how can it be if i havent changed anything on this computer, its the same as that time when i bought it, so how can something be changed?? everything is the same, im telling you, it happens always to me and i don't know why. it seems God is doing that for me... mouse works, everything works, but NO, keyboard doesn't, **** it... and, while playing games, it works almost perfectly, how I wrote, only one time it disconnected magically... I don't know what to do else.
btw, as I see now, on generic usb hub, it shows that mouse and wi fi adapter are connected and how much power they use, but it didn't show anything about keyboard. Can it be the problem?
You probably have more than one usb hub. For EACH hub, check how much power it says is available, and for each device, how much is required. For example, if you have 3 USB hubs, check all 3. The sum of the device power required for each hub must be less than the available power. For example, if it says power available is 500ma, and one device on the hub uses 200ma and the other uses 200ma, that is OK. A lot of times the type of device is not listed as expected, but it should show up as something. for example, it may not say keyboard, it might say "unknown usb device" or HID device, or something else, but it should show up as something.
i checked all hubs, and there is no keyboard. last time mouse and wi fi adapter was on one hub, and now only adapter is, and i cant see mouse like keyboard anywhere, but it works, of course not a keyboard. and i dont get it. while im playing games, my keyboard always works, but while im not doing anything or surfing internet, it stops working and doesnt come back. im really tired of this...
Well, that is the first time you have said that it stops working after sitting there. I thought it just went out while you were using it. So it is probably going to sleep when not being used. Try doing this to ALL of your USB hubs in device manager: In Device Manager, expand "Universal Serial Bus Controllers", for each USB hub, double click it, then click on the tab that says Power Management, then uncheck the box that says "allow the computer to turn off this device to save power". Perhaps that will solve the problem.
As for why all your devices don't show up, I don't know why that would be. But see if changing the power sleep works.
Did you ever try a different mouse or see if the keyboard problem goes away when your mouse is not connected?
I tried without mouse, and it didn't work, or maybe i did something wrong. First I unplugged all usb devices, then I shutted down pc, plugged keyboard and turned pc on again. On windows, it showed that drivers are being installed and when it finished, message didn't disappeared and when I clicked many times on windows button, nothing happened, or maybe it was because of a message that didn't disappeared, I don't know... Anyway I think it's useless to look for solution for my problem, I tried everything and nothing helped me... Maybe it's time to buy a new MB, I don't know...
