I am seeking an advice to those who are using diskpart to format and set a USB stick as bootable. I am recently using this, but I often get an error 68: ran diskpart to change drive letter – device unavailable. I wonder why this happens when in fact I am following all orders in its command. I am really confused. Please help me fix this issue. Thank you.

I want to know the exact function of Windows hot keys specifically F5 or Ctrl + R.

I would like to know this because when I use these hotkeys in Windows Explorer, oftentimes I notice that the windows’ displays would change.

The files then would be sorted in different folders. I did not expect this to happen. It’s quite surprising for me.

What I know is that these hot keys are used to refresh the windows.

Kindly provide me the exact function of these two hotkeys or the exact explanation for what I have experienced as stated above.

Thank you, so much.

I need advices on how I can carry the fiber into the server room in order to supply all my servers with gigabit. The switches I am using are Cisco 3500G and 2950G with BIC ports. I’m having a difficult time to downsize the servers to 100 MB by using a standard CAT5e cable.

I am having problems with my newly bought Mac book Pro 13”. The battery is not charging when the computer is on. But when my computer is asleep or booting, the battery will charge the usual way. When the computer is on, the battery will drain and a warning message will be shown that there is no power source.

A hallow insight proves some results that until now are not working even when trying.  Some of the steps that I have tried so far are:

-Restart

-SMC reboots (l-shift + option + control + power)

-Manual installation of Thunderbolt 

-Used a tested working power adapter.

I want about the causes to get the problems of any computer.

Please help.
