CQ-nnnnn what is nnnnn , may Cq57 made, all different nnnnnn
QC-100,.-200.,300, 400, series
your service tag tells you the full model number.
nor the OS (unstated)
XP, VISTA, W7 or W8?
this is what was used for the full series of production runs.
and they are NOT THE SAME.
tell what BACKLIT means. LEDs dead but at least name ONE>?

Please tell the helper this.
what OS first.?
tell exactly what Backlits (lights) fail, name them.
caps lock or ? what? give examples of what fails and what you are attempting to do..
on my newer HP, there are no keyboard lamps at all
not one but the HP has back panel that glows for that.
but needs the HP software loaded to make that work
only HP software works on that feature, period.

what operating system is this.?

the CQ57-400 is the last series is this it. why must i guess?
support for it is limited to this.

ill guess 400 for you as 1 example
then ill guess w7 32b
then you see this and load all these driver.

now il guess 100
here

looks like last one made was 2012 (Compaq ended in 2013 at HP)
so has support until 2022. at HP.com
load all your drivers for you PC on the HP page.
skip BIOS. (line)

the problem here is HP used 2 processors here.
Intel
and AMD
mixing drivers up is problematic. here.
takes skills to do this.
why not ask at HP do this is.
real HP forums.... BINGO?

SOURCE: Can I replace my non backlit keyboard with a backlit one?

If it is for your exact model than that keyboard should work. The backlight function is built into the keyboard itself not the laptop. I hope that helps

How to turn on keyboard backlamps on compaq cq57 laptop.


CQ57 what, it has full service tag.
what is the tag tell you. post that please.
http://pcdied.com/TAG-jive/tag.html


with that the manual on your PC is 100x time more easy to find
on that matches perfectly is the correct book.
and then all things you can push is covered

here is my wild guess. this?>
https://support.hp.com/us-en/product/compaq-presario-cq57-200-notebook-pc-series/5091489/model/5111956/manuals


are you asking for all keys to glow in the dark
or asking how to type blindly in the dark, be so nice of you to tell why you need this feature, no?
or only the normal keys,
caps lock.
Num lock.
name a key or some.
the above manual shows no such thing
why do you expect this.?
others have it and you dont and therefore want it?
others have differnent PCs.
others have disktop and then bought $100 keyboard that does that from CORSAIR. like mine ,now.

I have a compaq Presario CQ57 laptop and cannot get the up/down etc arrows to work. Don't have a numbers lock key so I don't know how to get them to work again.


Here are some options:
1) Use an external number pad
2) Use an external keyboard
3) Replace the keyboard (a small Phillips screwdriver and a flat head are all that are needed.)

I would like to mount on my laptop (Compaq Presario CQ57-304sl) a backlit keyboard...i've seen some Hp laptops with very similar keyboards...is it feasible?


I have a Pavilion M7 that had a back lit keyboard. Unfortunately it was for the wrong country so I changed it for a standard UK keyboard. Have a look on ebay for keyboards, there may be one available for your machine.
