Re Laptops

The tolerance level is around 10% of the input voltage of the charger for a laptop
So check the rating plate of the charger.

If it says 19v and you have hit it with say 23v you should get away with it however if you hit it with 30v+ then there is a good chance that the voltage regulator circuit is fried

Re Mains Supply

If you are talking about static electricity hitting components then all bets are off as they can run into 1000's of volts.

If it was a lightening strike then again you can get some really big voltages down power and phone lines etc.

Normally Routers and Modems get crocked first.

Keyboard of FMV-7000NA2 is not functioning

Is the power coming into the system? Does the charging light lights on?
If it is the case then replace the charger.
If it is not the case charging circuit should be replaced. Small work not very costly. But if you entire motherboard is damaged by high voltage or a fluid contamination or ants going into the motherboard, then you will have to replace the motherboard.

Car says high voltage on dash

This message means that the cars battery charging system (CONSISTS OF ALTERNATOR) is not being regulated properly, the voltage output of the engines Alternator exceeds it's design spec. This can be a false warning or the real thing, if it a true high voltage condition then you risk damaging the various electric and controls modules in the vehicle. O'reilly and Autozone parts stores will test your charging system for free and report the findings to you. I strongly system you attend to this ASAP to avoid possible damage to voltage sensitive modules and electronic component's.

Cyberhome ch-dvd 300 player willnot come out of standby and willnot reset after holding reset for 30 sec

Possible failure of the processor. You can shut down, power off the unit completely. Allow time - few hours - for the voltage to drain off thereby resetting any error voltage on the processor. Now repeat the resetting when you power and if there is no response the chances of the processor or motherboard having errors/damaged components are high which will require a voltage/signal/logic trace in the processor

I have a LP156WH2 LG display from an acer notebook and i can see the image but the led backlight does not turn on, it had a led open i replaced it for an identical one and still is not turning on, i live...

Check the supply voltage to the backlight LED's. If it's too high and thus causing the LED's to go open a new panel will just become junk when powered on, and you may have damaged the replacement panel you already tried. To check the voltage just measure it at the cable end you connect to the panel. If no voltage bad motherboard. If too high still a motherboard issue, but you might be able to regulate it with a simple solid state voltage regulator.

Yes you can. Any DDRII RAM can function at 1.8v.
Every memory module has profiles written into it, this allows it to function at various speeds and voltages, and 1.8v is the default voltage for DDRII.

Voltages above 1.8v are used for overclocking, to take full advantage of high speed DDRII memory you should manually set the voltage and frequency in your motherboards BIOS (accessed by pressing DEL or F1 during boot), if your motherboard does not have options to set these parameters manualy then your memory will function at the default speed and voltage

Hope this helps!

Apg video card

Use AGP 4x card. It can either be 0.8V or1.5V.
Using the wrong voltage card with the wrong motherboard may result in damage in board and card.
Also, if you install a card that is not compartible voltage with motherboard specification, the card will not run.
Good luck.
