Difficult to say where the sound circuitry is located. I would visually inspect the board and remove all residue of the water damage. The logic board needs to be cleaned or replaced. The part is available on common auction websites so you can try the repair yourself. There are also independent Laptop Repair places that will try a clean up Laptop Repair NYC.

Hi, my acer aspire 4930's keyboard not functioning correctly.. when i press letter "a" it appear as "A1" same as "Q" appears "Q1".. pls help me


Try cleaning the keyboard with a clean, dry paintbrush just in case there is anything stuck under the keys. Once you have cleaned the keyboard try typing keys to see if it does the same thing. If the keys type as normal then you have resolved the problem.
If the keys still type other characters along with the letter then there is a strong possibility that the keyboard needs to be replaced.
This usually happens when something has been spilt on the keyboard causing it to type random characters or the characters directly above or below them.

Seeing as the keyboard is a laptop keyboard you can use a wireles/wired keyboard or you can use the on-screen keyboard if you can't get the keyboard to work.

If there is anything else please post back.

Good luck.

I spilled drink over my laptop and i turned it on and saw smoke i think i burned out the motherbored and i need to fix it as cheep as i can do you no anywhere ?

There is no way to know the extent of the damaged done to your laptop. I can only guess that the following parts could be bad, motherboard, battery, optical drive, keyboard,etc, addition laptops are a pain when it comes to disassemby.

The rules if you spill a liquid on your laptop
  1. DO NOT apply POWER
  2. Remove the power adapter and battery as quickly as possible
  3. Blot up as much liquid as possible
  4. Remove all drives and allow the rest of the liquid to drain
  5. Use a hair dryer on low heat to assist in the drying process
Please note that soda leaves a sticky residue that can cause more problems, more disassemby of the laptop might be required

Wine spilt over keyboard, now when I press the power button the hard disk light comes on for a nano second and nothing else happens.

If this is a laptop, then liquid probably infiltrated to the critical electronics. Dry off the laptop as best as possible and let it sit for several hours. Powering it on may have permanently damaged something due to a short caused by the liquid. I would not recommend disassembling the laptop to dry it out. You will need to allow it to dry out internally before attempting to try powering it on again.

1. Remove the battery.
2. Remove any service covers you can find, such as the cover you would remove to install additional memory.
3. Wipe off any liquid you can see. Carefully try and get into spaces between keys if possible. avoid popping the keys off the keyboard. They aren't easy to get back on in some cases.
4. Leave the laptop powered off and allow it to dry for at least 3-4 hours, probably longer.

My lapto keyboard is frozen. I was cleaning the screen and I think the screen foam dripped onto the keyboard.

strip the laptop clean components with non conductive fluid(spray) and then blow dry with anti static blower allow to air dry for day or a few hours then re assemble and hope that nothing lblew when the dampness got into your laptop.

How to fix an acer 5515 laptop after it fell in water

Disconnect from the AC adapter, remove the battery, remove the trim piece(bezel) that houses the power button, and remove the keyboard; no need to unplug the ribbon cable.

Turn it over with the LCD lid open like to be sure there is no moisture inside; you can use a hair dryer t odry the inside (not a heat gun). You may need to remove the rubber bumpers, screws and trim around the LCD display, and do the same.

Reassemble,connect power, and try; but if its competely dry, and it does not power-on, is erratic otherwise; the motherboard is done - trash it.

Computer wont turn on

How long ago did this happen?
Remove the power adapter and the battery.
Remove any removable covers from the bottom of the laptop and look for any signs of liquid. Leave the covers off for a couple of days to allow any liquid or moisture to dry up.

Press and hold in the power button for up to 60 seconds to discharge the laptop.

When you are sure there is no more moisture present try starting the laptop.

If it still won't turn on something may have shorted out during the spill and you will probably have to take it to a repair shop.

I see many cases of spilt coffee/pop/beer/liquid of some sort spilt on laptops at work, and it is rare that good news accompanies it. It is rather impossible to clean out a laptop entirely. Your best bet is to get your data off the hard drive, buy a new laptop, and transfer it over. This may seem harsh, but it really is your best option if you do not wish to lose data.
