Question about HP Cameras

1 Answer

I have a HP camera CW450t camera and cannot turn it on with the power button on top. I know the batteries are good because I can turn on the camera with the review button and review the pictures that I have taken. When the power button is pressed the green light on the back of the camera flashes but the lens does not come out and the led screen does not come on. when you take your finger off of the on/off button the green light goes off as well.

Had the EXACT same problem with the CW450 model. I called support because I was mad and wanted it replaced. The support tech helped me through the issue. The answer is- NiMH. Alkaline batteries are unstable and not powerful enough for use with this camera even though the camera supports it. He asked me what I was using and I told him Alkaline. He said try some NiMH right now- by dumb luck, I had a charger in the wall with nickel batteries. This is what he had me do:
Put the NiMH batteries in. Take out your SD card. Turn on your camera. Go to options and go to memory kit and format. Go to options and do a factory reset by selecting Reset All. Turn off the camera. Put your memory card back in. Turn it back on and go crazy with it trying to take video and pictures.
I have been messing with it for an hour now and it works perfectly. He told me to test it for at least 2 days and if it still malfunctions they will send me a new one. If the fix I shared with you didn't work call them up and work with them. 1-866-694-7633 if you are under warranty they will replace it for you.

My camera is a hp cw450t It continualy reads memory card locked how do I remove it ? thank-you in advance.


Look at the memory card. SD cards have a slide switch along one edge. The position farthest from the contacts locks the card, protecting it from writes. The position nearest the contacts unlocks the card.

I had the exact same problem. What I found out was that certain types of batteries have more power to power the camera and make sure the batteries are brand new because they might have been sitting in your cabinet or where ever and run out of power and not be able to open the lens or turn the power on, and the manual (disk) that came with the camera says not to take the batteries out if the camera's on and if your lens isn't opening properly it's because your batteries are low on power. Well I hope I helped. Bye.

Hp photosmart R927. No power, no operation, no LCD, battery good.


Your problem may be due to corrosion on the battery contacts inside the camera which can prevent the full power of the batteries from flowing into the camera. Try this free fix before you do anything else: remove the batteries and wipe the camera contacts firmly with a dry cloth (heavy corrosion may require cleaning with a wire brush, steel wool, or sandpaper). Remove any residue that may have fallen into the battery compartment during cleaning, then wipe both ends of the batteries and place them back in the camera. This cleaning clears the problem about 90% of the time. If it doesn't work for you, the camera may have a problem that requires professional repair.

If this response helps, please take a moment to post a rating for me. "Very Helpful" would be appreciated.

The on off button is stuck in. is there anything you can do or do i just buy a new one.


Reset the camera
  1. Turn off the camera, if possible.
  2. If an SD memory card is installed, remove the card.
  3. Remove power from the camera as described below:
    • If you are using only batteries for power, open the battery/memory card door and remove both batteries.
    • If you are using only the HP AC power adapter, disconnect it from the camera.
    • If you are using both batteries and the HP AC power adapter, remove both batteries and the power adapter.
  4. Wait for 15 seconds. Then reinsert the batteries and close the battery/memory card door or reconnect the HP AC power adapter to the camera. If you are using both batteries and AC power, try each method separately.
Turn the camera on and off. If the issues is not resolved do the following

Connect the camera to the optional AC power supply
  1. Connect the camera to the optional AC power supply. Ensure that the AC power supply is connected to a working power outlet.

  • If the issue is resolved , you do not need to continue with the rest of the instructions in this document.
If the is not resolved ,then repeat setps 1 to 4 abiove but remove the batteries and keep the AC power adapter connected.

How to turn on the camera


aeloveforev9
all camera's have a switch, button or lever to turn the power on. look through the finder if any light is on or the meter needle is moving then the power is on. some turn on when the shutter button is pushed in slightly. make sure the battery is good and no corrosion is in the battery compartment.

Hp M525 repair needed


My wife brought this camera home from work for me to look at. It had the sunken/broken power button problem.  The T-shaped hinge was broken where it connects to the power button section. I couldn't see any way to glue or repair it that would be strong enough so I came up with an alternate fix.
The actual power switch is below the broken button, just a touch below the "ON/OFF" text. I decided to make a button that pushed the switch directly rather than pivoting like the original.
I needed a push-button shaped object with a shoulder on it (so it wouldn't fall through the hole I was going to drill in the back). I ended up using a small green LED (3mm size I think). I drilled a hole big enough for it to move but not so big it would fall through. I cut the leads off flush with the body and sanded them flat. The hole I drilled lines up with the little bump on the original plastic switch piece.
So I put the LED in place, the original plastic piece over it and added a little bit of self adhesive felt (that you would stick on the bottom of something to protect your furniture) at the top where the silver button is (just to keep the original button from sinking inward). I put the back on the camera and checked that the power button clicked nicely. It did so I put the camera back together and it's as good as new. 
And it has a snazzy green power button now.
So if you are handy you can probably fix the camera yourself.
Good luck - Greg

Power on n off


sounds like a battery power problem or problem with the terminal of the camera ; you know the point where the battery meets the camera.
I would recommend a service center

Camera wont turn on.


Main power led to on/off switch is crushed and not enough power gets through.
you have disassemble the camera.
I would think first before tring this.
Remove 3 screws on bottom, 1 in battery compartment, and 1 at very top of usb flap (look good).
Now slide the side piece starting at the usb flap then apply pressure to top and away from unit.
now look for 1 silver and three black screws (facing back and front, look good).
See the big red wire leading to main on off switch if it crushed thats the problem.
I replaced it with a longer piece of wire.
Remember to replace battery door first if it fell off during process.
*TEST NOTE: You can place batteries in and place a penny across the bottom to test before you put it back together.
