wow, posting with NO OS stated, no Operating system stated.
windows what?, OS2, Linux, what? be specific or help will not be correct.

connecting. we don't know at all what connections you have,
none stated?
is this an Ethernet cable (cat5/6-RJ45) ? to your ROUTER?
or wifi to your home router, what?

if Ethernet cable works and wifi not then we know is wifi only.
why not use a cable, buy one for $3 and keep it handy.

btw , the cables allows getting long winded windows updates 100x faster. or if installing an new or updated or restore OS even faster.

we have no idea at all what OS is there.
nor if it was upgraded to a higher version without HP support.
its and HP computer now, Compaq is gone.

if you look in DEVICE MANAGER.
see all net work chips there, ?
are all of them happy, no red, no yellow marks or missing ?
if yes, then your DRIVERS are wrong, or corrupted.
that is step one,
not get connected. get connected can not fix bad drivers.
so DM is first.
but first first is what , DRIVERS matching your unstated OS.

I have a Compaq/HP Laptop Model C762NR and I have found an intermittent cable I need to replace. I am looking for a cable that is bundled and connects from the motherboard on the left side, then runs...

this LT is a relic, there are no new parts
so go to EBAY, see that LAPTop there, what you see there is all you get. or wait for 6months each day checking, for hard to find parts.

that is and LCD cable simple ./

there is no HP(compaq) support on any pc this old.
leaving only the used parts market./

google that yet, like "compaq, laptop parts"
its like having a real old car, and needing parts.
hard to find, yes.

Possible failrue of the display unit. removve the panel and check the conection to the display. If there is any signs of the display coming on when the connecctions are touched clean and carefully look for any loose connections. If so use a thin iron to touch up the solder.

My wife dropped her computer and the plastic surrounding the keyboard cracked. The cover and everything else is ok. What is price for the plastic cover arround the keyboard? Is it difficult to replace?...

Well it is a bit of a mission to replace, however if you get yourself a Service manual, for your exact model, it will make it a lot easier, as for cost, less than $100.00 But I would check out eBay or shimmy up nice to your local PC repairman and you may even score one for nix... many of us have old laptops cluttering up the place that we would gladly give away to get some space back.

Compaq presario C762NR notebook pc I have trouble charging it, the blue light turns on and off. Once I plug it in I need to move the charger around in order to start charging

You either have bad wires or loose connection. Take the prongs on the plugin and bend them both outwards. Use wrench if needed. Bend them just enough so they will stay in the outlet without being loose. This is the most common problem with charging
