will CRC-2-26 clean a bad notebook keyboard
TinyTim
it's a Lenovo G530
...I have a notebook unit that has four unbearably sticky keys. C ,
D , (LEFT) ALT , AND SPACE BAR
I think somebody spilled sugar water on a portion of the keyboard.
I am a user... not a professional repair person. I cannot figure out
how to get the thing apart to clean the keyboard...if it can be
cleaned. I tore down a Z770 once and it was hell putting it back
together with all those screws...different sized screws. I think down
and up was 10 hours for me... and I did not always get the screws
where they belong.. They might have a 6mm screw but in three slightly
different lengths
One) can you pull off LAPTOP "keys" one by one and clean around
...and then replace the key? How do you lift them off? Considering
the sandwich construction, do you think an amateur like me can make
that a reliable computer?
Two) After reading their website,
http://www.crcindustries.com/faxdocs/tchdta/101.pdf
and after using the product for 4 years .... often on old electric
switches and motors....I am tempted to give the notebook keyboard
trouble area ....a good strong shower of CRC-2-26 .... and a piano
finger zip back and forth until the sticky keys are loose.
Then...turn it upside to let excess CRC drip.... and finally..... a
big shot of dry compressed air to blow the CRC and hopefully the
sticky fluid residue. I know the CRC is not a good solvent for sugar
water but it may have good enough electrical and lubricating qualities
to salvage the keyboard with removing it or having it expensively
cleaned by a priofessional.
what do you think folks?
I think I answered my own question....the keyboard should be replaced
and possibly professionally cleaned and if I cannot do it...only
someone else can repair it and make it like new. .....
So... I have 15 days to return it for a complete refund... $350
it's a Lenovo G530
or I might ask for them to refund me $180 and I will live with it.
I won

Replacement of the G530 keyboard doesn't look bad:

You have to remove the power panel first, but that doesn't look bad,
either:

It's possible to remove keys, but easy to break the pins on the hinge
underneath. And then difficult to clean inside the switch mechanism.

You already have a sticky, long-lasting film of sugar. Adding another
long-lasting film of oil probably won't help.
I'll add that I used to rescue desktop keyboards after someone dumped a
cup of sugary coffee in them by washing them in a dishwasher with no
soap, then giving them days or weeks to dry. Never tried with a
notebook keyboard.

I did it anyway...and it did work..... enough to make the keys usable

I noticed you have a lot of company..based on a number of computer
repair .blog site. One aficianado said maybe it would not be a good
idea with a laptop because of the
"sandwich" construction.....I'll see when I get it apart.
Thanks again for your time.and tips.

That's a pretty good price for a G530. I just bought one at
$649cdn. Mine is 4446-38U Notebook PC - Intel Core 2 Duo T6500
2.1GHz, 3GB DDR2, 250GB HDD, DVDRW, 15.4" WXGA, Windows XPp.

The price seems comparable to the one I got. Thanks.
