    Accidently spilt little coffee on HP Pavilion DV7 switch cover. Cleaned LED assembly with white spirit, and left it to dry for 48 hours. Still lights flash before POST boot. Unplugged and removed the battery for 48 hours, but the fault/problem not solved. Please help/advise. Thank you.

    All parts are cleaned and dried. I found the solution: faulty switch panel assembly board as none of the LED controls work.

    I found the solution: faulty switch panel assembly board as none of the LED controls work. That faulty assembly is replaced, and got the computer to boot-POST. However, in addition to that, I discovered there is no power going to the battery, and so trying to trace and replace the faulty parts (component level). Thanks for the three replies so far.

No post at all? No power at all? it sounds like the liquid got down into the motherboard and fried it unfortunately. Also this isn't covered by any warranty since it is considered physical damage. You will need to get HP to repair the machine, which they will. Give them a call at 800-474-6836

    Sure thing, well glad you have it operational again, to a point... But now you say you have no power going to the battery? That is very unusual, it must either be the ac adapter port or the actual transformer at the port that converts the ac power into usual energy for the battery. That should be pretty easy to figure out if you figured out that panel...


    Thanks

Hello,

It seems the coffee as gotten to the RAM slot, you will need to disassemble all the parts on your system, remove the battery, unscrew all the screws to access the RAM and hard drive, remove/disconnect all the IDE cable from the hard drive and leave them all to dry very well before you couple back. Ensure you clean the RAM and the slot, after the components are dried, you can now couple, that should fix the problem.

Take care.

Hi! Please remove the battery first and then let it sit for another 48 hrs. This may reset the system and get it back to normal working condition again. Please write back on the progress. Hope this helps and thank you for using FixYa!

Found this while looking for Battery Release Latch. You may find it interesting,

Latch is part of the Base Enclosure. (Bottom Cover)

Point?
From where I sit, (Computer chair at my house.....), it looks as though you may have to disassemble, to access where the Battery Release Latch goes, to reinstall.

How do I remove/replace the keyboard from a HP Pavillion dv7-2277cl


1. Remove 6 screws from the bottom of the case (as shown). These screws hold the accessory cover.

2. Remove one screw securing the CD/DVD drive. Slide the CD/DVD drive to the left to disconnect it from the motherboard. Remove the CD/DVD drive.

3. Remove all marked screws from the bottom of the notebook.
The yellow circled screws secure the keyboard cover, and the green one secures the HP Pavilion DV7 keyboard.

4. Turn the computer display-side up and open it as far as possible. Insert a guitar pick or small flat screwdriver between the keyboard cover and case and slowly move along the side.

5. Lift the keyboard cover. Be careful, it's still connected to the motherboard. Release the zero insertion force (ZIF) connector and disconnect the cable from the LED board. Remove the keyboard cover.

6. Remove the four screws that secure the HP Pavilion DV7 keyboard.

7. Lift the rear edge of the HP Pavilion DV7 keyboard until it rests at an angle. Slide the keyboard back to disengage the tabs on the front edge of the keyboard from the top cover and rest it on the display.

8. Release the ZIF connector to which the keyboard cable is attached and disconnect the keyboard cable. Remove the HP Pavilion DV7 keyboard.

My ph pavilion dv7 touch pad's light is off, what must I do to get it on again?


Looking at a picture of the laptop, it is like most HP computers. There is a button directly above the touch pad. This is your on/off button. Press it and wait a few seconds, and the light should turn blue.

I managed to crack the LCD on my hp dv7 laptop. What is the easiest way to get the screen out to replace it?


Typically there are two screws on each hinge that is mounted inside the back of the laptop. You'll have to get the top indicator panel off to get to the connector(s) coming from the LCD. The usual process is unclip the wiring harneses and then remove the screws, and the screen and hinges come out. Replacement is the reverse.

Some laptops you have to remove the entire top of the laptop (keyboard/touchpad first, then the cover assembly. Others you can just pop the rear button cover (usually where the LED indicators and power button are located) and access the LCD connectors there. Best way is to go to HP and find the service manual information which will tell you how to remove that specific piece of hardware.
