re you allowed to just type x^y? As in x being the root and y is the exponent? If not, and if you're using Microsoft Word, type the number you want to do. Highlight the exponent and press Ctrl, Shift, and = at the same time. That should do the trick.

You probably have a Windows O/S on your Vaio. You can open *Device Manager* and check to see if your DVD drive is shown and doesn't have a red or yellow exclamation mark on it. It it has such a mark then it's got a problem. You can right click on it and choose *properties* either way and you should have a properties dialog box open up that will tell you if the device is working properly or not. If it's not working properly it could be the device drivers (software) got corrupted, deleted or lost. The dialog box should give you the option to update, roll back or re-install the drivers. Or, if the device spins up but does nothing in the way of reading or writing, try cleaning the laser lens with a cotton Q-tip slightly damp with isopropyl (rubbing) alcohol. These lasers can get dusty and thus malfunction. You can check in File Manager. If the drive does not show in File Manager then it has a connection problem or it's dead. Good luck!

Go to Google Chrome Web site & re download.

Hold down the power on/off button for 5 to 10 seconds. This should force the computer to shutdown.

Try removing the ram chips and if you can get to it the button battery. Wait a few minutes then put it all back together and boot. If the issue was with the BIOS that will reset it.

This can usually be achieved but firstly you would have to prove the laptop belongs to you and isn't stolen - A Sony laptop will usually have a Microsoft Windows operating system and passwords can usually be changed using a 'boot' cd or password recovery disc (I'm presuming you haven't created a password recovery disc or you wouldn't have posted your question on fixya) - Download a boot cd and burn it to disc using another computer - set the start-up options on the locked laptop to 'boot from cd first' (You'd need to press one of the keys as soon as your laptop begins booting up to get into the BIOS or SETUP so you can choose this option - it might be shown on screen or you can Google it to find out which key to press) - Once you've booted from the cd instead of from the operating system on the laptop's hard drive you should follow the instructions on screen - then take out the cd, change the boot settings back to 'internal hard drive first', and re boot into Windows

No. If you can use the screen still, go ahead and continue. You are not hurting it.

Which device are you looking for? The laptop has many. What is your OS?

use an external usb keyboard and order a new keyboard for the laptop.

That usually means that the screen has a bad edge connection. If you can put up with it then it wont affect the life of the screen.

My question is the laptop turned all the way off when you go to shutdown do you click shutdown? Because it may show this light if the laptop is not turned all the way off. Also does it only do this when its plunged in? Some time there is a light to indicate the laptop is charging. cheers best of luck

If WIFI is turned off, look on the top row of keys for a key with a picture of a litte antenna thigh. may be F12, it is on mine. this key turns the wifi on and off.

This is something that should be tackled by a professional repair technician. It involves removing the top of the laptop and getting at the keys. It may be something simple such as cleaning the switch under the key, or it might mean having to replace the whole keyboard switch system.
