Question about Compaq Presario CQ60-212US Notebook

1 Answer

Hello, I have a Compaq CQ60 and have problems with the LCD display, which works intermittently. I had the entire LCD replaced about 4.5 months ago. Worked great until a couple weeks ago, the LCD went black again, no dim picture, just black. The laptop itself works fine, and I can view display via external monitor. The LCD came back on about a week ago, then again this evening. Could it be something with the internal display switch? I do not see any such switch externally, as I thought it might be getting stuck. Or perhaps a cable of some sort. Please advise, I would like to try to fix myself, as don't want to put more $$$ into this machine. Machine itself is GREAT. Just not currently functioning as a "laptop". Thank you.

Is this a CCFL LDC
if yes the inverter is bad. (a card tiny, and thin)
its old LT.
the books are gone now.
the service book tells you how to replace the CCFL inverter
find a used good one is problematc.
why not buy a newer LT
or just run the external screen and be happy

I guess you have not read the user guide yet?
about the VGA hot key.
mine has.:
1: external only
2: internal only
3 both
4: auto. (i think only my newer HP has this)
mine is Fn+f4, but on a relic compaq, gee buy the book,
or google search for it for weeks,

next time post to HP< there is no COMPAQ for years.
hp owns it. totally

ever seen this before. the fail like LT batteries do. often.

SOURCE: My compaq presario x-1000 hard drive light and dvd rom light flashes. Won't boot up.

Try disconnecting the harddrive from the case and then place it back in. if that doesn't help you may have a faulty drive, hows warranty? Compaq / HP would fix it for you free if you still have warranty.

let me know.

Thanks,

SOURCE: monitor screen stays black even though it's on

Remove the memory from your unit - power it up it should beep if full communication is still happening across your m/board. No beeps you board has died. if it beeps and your using two diffent memory modules just fitt one leave the battery out and power it up = if no display pull power swap out the memory and try again. if display occurrs you have a defective memory module - throw that failed unit away

SOURCE: Hello. I received a Compaq Presario 1620, needed

There are a few things that come to mind:

  1. Turn off the laptop and leave it off for 5 minutes- then restart it (with the external monitor unplugged). Check to see if you have your video back.
  2. Unplug the monitor, then hit the hotkeys again to switch back and forth between inputs- does the video show up?
  3. There could be a loose wiring/connection issue between screen and the rest of the laptop. Sometimes fiddling around with opening and closing the lid will work. Otherwise, you may need to open the laptop to check the connection between the two (not recommended if you are not good with fiddling around inside computers), or taking it to a tech who can do it for you.
Hope these answers help.

Hi, I have a laptop compaq presario cq 60 .When I switch on the computer the fan start working but the screen is black doesn't start .What could be the problem? Thank you


Hi,

If you see power lights but nothing appears on the screen, it could be a "POST" (Power-on Self Test) problem or simply LCD problem.

Here are some steps that you can try. One of these may work on your case.

1. Remove the battery and the ac adapter then press the power button for at least 20 seconds to drain electric charges left on the system. (You may need to repeat this step to get it work.)

2. If above step doesn't work, try to plug in an external monitor and see if you get display from the external monitor.

3. If you get display from the external monitor, I'm sure your having problem with the LCD components. In this case, check and replace faulty LCD backlight, LCD cable or LCD inverter. The LCD inverter is often a culprit.

4. Try to reinsert the memory module/s (RAM) of the unit, try using one RAM at a time to see if it works. A faulty RAM will cause the laptop not to POST.

5. If reinserting the RAM doesn't help, most likely your motherboard needs to be replaced.

Hope this helps.

Compaq Presario CQ60-215DX. Doesn't start


You will need to buy a new battery, there is no way old one will be OK. To see if it works, remove battery, and use wall adapter ONLY, PC should work fine. If not maybe Flat CMOS, replace, If replace and still NO go.must be bad motherboard (maybe try charge battery 5 hours left alone)

Entire Keyboard and Touchpad don't work! Compaq Presario CQ60


Fantastic, thank you for posting above that removing the battery sorted the problem. I had exactly the same problem as you with being able to sign in with my password but neither the keyboard or touch pad worked past this point. It's weird that the keyboard worked for signing in with the password but then didn't work anywhere else. Wonder what causes the problem coz I can't think of a logical explanation. Anyway I didn't have to hold the on/off button down for 2 mins. Just removing the battery and then replacing it cured it. I can't thank you enough for helping me to solve this.

Compaq presario cq60 keyboard


Hi,
If the problem is intermittent then the problem could just be foreign objects like crumbs and hair that's trapped under the keys.

Turn the laptop off and stand it on it's side with the lid open. Get a soft, dry paintbrush and brush the keys, gently tap the keyboard in various places with the back of the paintbrush to help dislodge anything that's trapped.

Once your satisfied all the keys are clear turn the laptop on and see if it has made any difference.

If it has not then you may need to replace the keyboard.

Good luck.
