Re: hp photosmart m22 wont even turn on dont no why or...
Read 'nightdivers' earlier answer
The problem is that there is a small, less than 1 cm rectangular magnet, embedded in the slide cover just to the right side of the "HP" logo and above the "M22" marking, the magnet activates a metallic reed switch on the circuit board when the slide is move to the right to "turn on" the camera and take pictures also exposing the lens. When the slide is moved to the left, the reed switch contacts are off. This would be an easy fix for a camera shop (as long as you tell them what the problem is) and they would not be able to overcharge you with the knowledge you now have... This is a great camera, and would be well worth the fix
My addition is:
I used a magnetic ended screwdriver and lightly tapped the magnet end over where the badge/logo covers when the slider is opened.
hey presto, my camera sprang back into life!
reed switch must have just stuck

The M22 won't work with your 4GB SDHC card. It only works with MMC and SD cards up to 1GB in size. Having said that, if after cleaning the battery contacts and putting in new batteries, it still doesn't work, I'd toss it and get a newer camera. Giving its age and (lack of) capabilities, it just isn't worth repairing.
There is a magnetic reed switch in front of the power switch and a small permanent piece of magnet just behind the hp logo of the slide door. Try placing a stronger piece of magnet in front of the logo and slide the door again and listen for a click when the reed switch closes. If not sound then the switch could be defective. Replace switch if necessary.
Could be a couple different things. Was the camera dropped or exposed to liquid? If so it may be a problem that needs repair by replacing the damaged parts.
One thing for you to try is to find the small battery door switch beside the memory card slot, is it damaged or missing? Without this switch the camera will not turn on. Put in the battery and with the door open press down the switch gently with a pencil. Now press the power button... does it power?
If it's not that switch then it's most likely the fuse which has shorted out. If you can solder well then you can replace the fuse, they are pretty cheap to buy. Another option is to buy a defective camera online and make one good camera from the two.
If that's not an option you can have somebody repair it for you. If its out of warranty Canon will want $150+ to do it.
DONT throw it in the trash! It's still worth money even if you don't want to repair it, sell it online or sell it to us; we are a digital camera repair business (Google: Darntoothysam com) and would buy it for parts if we can't get the parts to fix it for you.
Hope this helps

You can try switching over to 2500 mAh Nickel Metal Hydride rechargeable batteries and you will see a difference.
Digital cameras with zoom lens need more power than what can be supplied by ordinary batteries.
use different memory card, most troubles i always encountered in digicam are caused by memory cards, many cards works in pc but not in digicam.
hey tapping side by side always takes away the trouble. [;0)
