Question about Compaq Computers & Internet
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
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.
mixing drivers up is problematic. here.
takes skills to do this.
why not ask at HP do this is.
real HP forums.... BINGO?

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

Yes it can , If you know what your doing , open the laptop up to expose the keyboard , then clean and dry the keys very well and put it back together , let me know what happens ,,,,,,Goodluck Roy
