My labtop makes a high pitched siren like noise when you initally boot it up, the mouse icon and various other icons flicker randomly from time to time, and the computer usage is over 50% constantly when it use to run at 4-25%.

Question edited for clarity and fix the model number, no 'o'.
Question moved from Televisions Category to maker Category.

Try and find a repairer for the board, this make does not have a maker website, so made in China. I can't think of anything on a PCB that would make a noise.

Hello,

its not a system problem, but a mouse problem.

The mouse is beginning to develop some faults and in no distance time, the mouse might not function again.

Go to Control panel of your computer and click on the Mouse Icon, check the settings and see if you could do some adjustments to make the mouse function perfectly.

But if the mouse still malfunctions, then I would advice that you get another mouse straight away.

I wish you all the best.

It sound like you may have sound processor problem which is part of the main board, I would also look at the 12vdc from power supply to make sure it is clean DC.

Hello.

In order to fix Your iLO Mp3 Player please follow these steps:

1. Please connect the player to a rear USB port on the computer. The display should show “USB Connected”. (If not, please press the power button.)
2. Please make sure that all unused programs and applications are closed. You can close the applications by closing as many of the icons in the lower right hand corner (by the clock) as possible.
   Download the Firmware.
3. Click Open to initiate the download.
4. Double click on the ILO or Siren folder icon. There will be 14 icons.
5. There will be a Setup icon that looks like a box with a blue line on it; please double click on this.
   Then click Run - this will open the Install Wizard.
6. The Install Wizard has the instructions on the screen as you go through it.
   Once the firmware has installed, please click the Start menu, then Programs.
7. Look for the icon that says ILO or Siren, and then double click the Firmware Update to install to the player. Depending on how severe the corruption to the firmware on the player is, you might have to do this step 2 or 3 times in order for it to completely repair the firmware.
   
   

Additional Tip: The player itself requires a lot of power while flashing the firmware. We suggest disconnecting all USB devices from the computer except the MP3 player and mouse; you can reconnect your keyboard once the firmware has been flashed.

Good Luck.

Right-click on the speaker icon in the lower right of your screen and choose Open Volume Control and check all volume levels (make sure they are not set to high). If this doesnt work then when you right-click, choose Adjust Audio Properties and search around for volume controls (maybe try the Speaker Volume button).

There is some hard ware problem for this physical site visit required.

firstly , i just want to let you know that it is a laptop not a labtop. But anyway In windows you cannot make a restart from the keyboard. When this happenes, just hold down the power button untill it shuts off (about 10-15 seconds)
