Hi,

This is a notebook not a desktop computer.

Try this and let me know if it works.

Remove the AC power cord and the battery. Hold down the power button for 30 seconds to dispel any residual power from the laptop.
Then just plug in the AC power (leave the battery out) and try to boot the laptop up.

If it boots up let it load the operating system and then shut it down. Reinsert the battery and see if it will boot up.



Good luck.

Fit my Compaq Presario CQ61?


accu Compaq Presario CQ61 100 percent compatible with you Compaq Presario CQ61. I bought two Compaq Presario CQ61 batteries from http://www.accukorting.com/compaq-presario-cq61.html two weeks ago, I felt very surprised, because it fits nearly as good as the original battery.

I've had my compaq presario cq61 for about 2-3 years. A while back it would occasionally have a kind of shaky/blinky screen but just in the past week it's like the screen has stopped working.


The problem may be due the graphics card or data cable or backlighting.

The data cable can be severed over time though opening and closing the display. This can be replaced.
The backlighting/inverter dies, some-times the windows desktop screen can be seen if one looks carefully. This can also be replaced.

Try connect your notebook to another computer's monitor via VGA or HDMI out.

If this works then the problem lies with your LCD screen.

Take care!

I have a Compaq CQ61-319WM & when I turn it on the screen is black, the caps & the # locks key blinks...what could be the problem?


Whoever wrote the answer to this is awesome. I have the same type of computer and it would not turn on even though the charging light was on. So I took out the battery and unplugged it. Then repeatedly pushed the power button. After that I put the battery back in and pushed the power button and it worked! Thank you sooo much!!

I have a Compaq CQ61-411 Notebook the battery went out the computer was working great but a message came up saying replace battery and it cut off and would not charge back up so it took me a few months to...


HP.com
see your manuals and what the blink codes mean.
each PC has PDF manual that covers that.
blink codes are BIOS warnings.
to tell you what catastrophic failure happend
like low power
bad memory
processor dead
GPU dead.
and more, some have 12 errors possible (newer)

if the BIOS screens are dead, its lost power.
or one of the above.

Please kindly reply me, My Hp Compaq Presario CQ61 would flash the caps lock light severally thereby preventing the system from entering into bios. This would last for a while.


Go to this link that is for your PC.

http://www8.hp.com/us/en/support-drivers.html

Select "Troubleshooting"
Type in or copy/paste your PC - Compaq Presario CQ61 (Look for the US version)
Then type in your problem at - "Key Word or Questions" Caps Lock Light Blinks


Follow instructions from HP Site that basically say shut it down, remove a/c, remove battery, press power button for 30 seconds. disconnect all usb and other connected devices. then insert battery and turn on.
Hope this helps'

We have a Compaq CQ61 and my son turned it off and back on and the screen is black. We tried the brightness, turning it off and on again and nothing is working


Hi,

You can try the following steps,
  • Turn off the notebook
  • Disconnect the power cable
  • Take out the battery
  • Press the power button for 15 secs (to drain out static electricity)
  • Connect the battery back on the notebook
  • Connect the power cable
  • Turn on the notebook
Note: You may also check if the light on adapter is on (if there is any) and the light where the power cable connects to the notebook is glowing. If the light is not glowing it is the adapter which went back.

Regards,
Shrey

I have a presario cq61 and have forgot my password can u help


Try starting the computer in safe mode. Turn on the computer and once the COMPAQ screen clears press F8 a few times - don't hold down the key however. Winodws stops loading at teh Startup Options screen (black, text only). From that menu use the cursor keys and ENTER to select "Safe Mode". Once Windows loads (it may look humungous!), login as the Administrator (which should now be visible). Use this account to reset your forgotten user password. Restart once complete - the computer will automatically start normally.

I have a Compaq presario CQ61, an when i turn it on the screen is black other than some really dim writing i can hardly see. Help?


Try attaching an external monitor to the laptop & see if you could get any display on it. If this is successful, then you might have either a faulty LCD cable or screen inverter board.
The LCD cable transfers data signal from the motherboard & video card to the LCD screen. It also supplies high voltage DC power to the screen inverter board. The screen inverter board works as a power supply for the backlight lamp mounted inside the LCD screen. It converts low voltage DC power to high voltage AC power needed for the backlight lamp.
