This my sound simple, but is it muted through the speaker icon (a red line through it) or by inadvertently hitting a button on he laptop itself? The wifi on many laptops can also be turned off by hitting button on the keyboard, the wifi light or led itself.
a model number can be helpful. I also have ability to remote in to fix it if I is online.
If your app was auto saving, then yes, it should be in the hard drive. Sounds like the cpu might have gone, but if the hard drive can be removed and placed in a ~$20 enclosure with a USB interface you should be able to use anohter computer to access the files.
As long as the voltage is correct the ma/h can be as high as you want. It just means it will last longer if it is higher than 350ma/h The music player will only use as much as it needs, the more there is available the longer it lasts.
If the voltage is incorrect it will damage the player, it's the voltage that pushes the current.
try to check out your video card and try to clean it or your memory card.
these are the steps to clean and remove corrosion on your cards:
1. open your cpu and remove your video card and memory card our the slots. 2. get an eraser and gently use your eraser to brush the pins to take off corrosion. 3. after doing this, gently put your card to their corresponding slots and press it so that the contact point of the pin and slot will hold so that your board will read your cards. 4. close the cpu and start your pc.
It sounds like your Windows Installation is corrupt. If there isn't anything you need on the drive, I would get a Windows XP CD (Look on the side of your case for a Windows Key, Get that version of the CD) Then I'd use that windows XP CD to wipe the drive and Re-install windows. If there is Data on the drive you need, You will need to invest in either a second HD, or You need to Install Windows on a Second HD and boot from that if you already have a second HD.
un-plug the TV, wait at least 30 seconds, now turn it on again and close your ear to the back of the TV while turning it on, pay attention on hearing a hogh pitching sound coming from the back of the TV, the sound may be quick and go from a lower frequency to a higher frequency really quick if this sound is present then it means the switching power supply. if you don't hear any noises then the power supply is bad. It could also be a bad horizontal driver transistor, it depends on the model TV you got.
Sounds like to me that either you're missing a bootable OS or its the harddrive. If it beeps, chances are the OS. You can buy a copy of Vista and have someone install that for you or you can do it yourself. But if you are nervous about such or dont know about computers, have someone else do it for you.
The poster probably refers to the computer itself as the CPU. (Not essentially a mistake, a common use of the term from history.) If so, the high pitched sound comes from a **** PSU. Changing it is recommended. It's taking it's dying breaths.
