Optical l.e.d. is out

Sometimes these things happen and the only way for you to fix it at home is remove the game, and let it dry out for a few days then try it again, BUT DO NOT TRY TURNING IT ON UNTIL IT IS COMPLETELY DRY or this will fry the circut board. If this does not work you will have to take it to a place to have it fixed.

SOURCE: spilled coke on my keyboard, how do we clean it

Hi

Thank you for your query

Best thing would be to get a damp cloth and simply wipe over the keyboard when the laptop is switched off, this will remove the stickyness.

Please ensure when wiping that no water travels into the keyboard which may cause you problems

Hi sir, thank you for raising your problem here.

About your problem sir, usually mouse nowadays, is plug and play. The meaning of that is when plug it to USB, it will be read by the computer readily.

But in your case, looks like the mouse is not plug and play, so you need a driver to be installed first so you can use your mouse. The driver of your mouse maybe in some CD in the package together with your mouse when you bought it. In case you lost it, you can download it over the internet. Try downloading it at http://driverscollection.com/?H=SWOP-35&By=A4Tech. You can also find other drivers there that you may need in the future.

Need any more help? Don't hesitate to contact me here. I am more than happy to share my knowledge with you.

I couldn't find any tech data for 35/55/65, but it looks to be similar to a large Yamaha I had to repair a couple of months ago for this same issue.

Keyboards can be practically difficult to work in, and can have very fragile interconnects. I wouldn't recommend anyone unfamiliar with working with electronic equipment and the risks involved to attempt this repair.

It may well respond to careful cleaning of the rubberized contact strip that sits under, and is actuated by, the keys. The pcb pads underneath that act as contacts should be cleaned too. It's a good idea to remove any loose dust and debris with a vacuum and a soft brush before lifting the contact strip out, this reduces the likelyhood of introducing problems on other keys. I then used some isopropyl alcohol and a cotton bud on the underside of the strip and the pcb pads. Very little pressure should be used in this process, as extremely fine layers of gold are involved, it's vital for reliable contact. I prefer not to clean areas for keys which were not affected.

There may be an additional issue, if the coke really was the cause then there may also have been acid corrosion of pcb track over the years. This should be repairable though. Inspection with an illuminated magnifier is recommended, or a cheap USB microscope will do a good job too.

Personally, I would say that this really is a job for someone qualified and experienced.
