Laptop will not turn on. I have two lights blinking

[999]

Have a compaq presario cq40 215wm and it will not turn on.  The power light and antenna lights are lit.  When I put a disk in the drive it sounds like it is spinning.  The monitor is still black.  I have connected an external monitor and it stays black also.  I have two lights flashing.  One above the scroll key and one next to the cap lock key.

I would suggest you follow the following document on identifying Blank Screen LED error codes to check what is the issue with the notebook:

Hi,

Try to perform a hard reset.

1.  disconnect the battery and ac adapter.

2.  Hold down the power button for 30 seconds.

3.  Plug everything back in and turn it on to see if you get a display.

If not, power down the laptop.  As soon as you turn it on, repeatly tap the F10 key to see if your notebook will boot into BIOS.

If you can boot into BIOS, press the F9 key to reset BIOS to default. Once you are done, visit www.hp.com using your product number to see if there are any BIOS updates for you pc.

This is a link in reference to the blinking codes you are experiencing.

Tried both, no change.  Cannot boot to BIOS.

I have also used two different charges and have tried a different hard drive.

Hi,

I would suggest looking at this document about blink codes for notebook computers. When you have a blinking LED light on the caps lock or number lock key it generally indicates a hardware failure. The document also gives you some additional steps on how to reseat the hardware on your notebook. Hope this is helpful.

Hey gabzzz, 

I'm sorry you're running into this power issue. The white light blinking next to the AC Adapter port is indicating insufficient power. I know you've already tried different chargers. Did you happen to try them in different wall outlets, perhaps a wall outlet that has a working lamp or TV plugged into it? Try plugging it directly into that outlet without a power strip/surge protector in the middle. 

Also, are you using the original adapter or a third party one? Make sure it is 90 or 120 W.

yups i tried different working wall outlets and two different charger which are original and with the same curent supply but it doesnt work

Ok I've got a couple of other things for you to try as well. 

• Hard Reset

1. Remove the battery, AC Adapter and all other peripherals

2. Press and hold the Power button for 10 seconds to drain all of the electricity out of the unit

3. Release the power button and reinsert the battery and AC Adapter

4. Press the Power button to turn it on.

Does the screen light up? Do you hear any spinning (hard drive, CD drive, fan)?

ALSO

• Remove the battery and just use the AC Adapter by itself. Then try turning it on.

AND

• Check the connections on the AC Adapters going into the power brick in the middle of the power cord.
• Inspect both AC Adapters for wire damage or damage to the power brick.

• Try both adapters in other computers and let me know if they work.
