Hi there I have pentax W90 and now it doesn't turn on, I put the battery on the charger and dew seconds light goes off,removed memory card and batery and put them back again nothing,

When you plug in the power cord is there any lightswhatsoever on the laptop, where the plug goes in or on the AC Adapter of thepower cord?

When you press the power button do you hear fans running, hard drive spinning,lights on the computer, hear any beeps or lights constantly blinking, hear theDvD/CD drive click and the light on the drawer of the DvD/CD turn on for asecond or two? If so the laptop is trying to boot or may have booted, butthe screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with thelaptop and why it is not booting. Most times it's a motherboard issuewhen you hear beeps or blinking lights continuous. Most times the problemis with the memory or Video Card. Count the Blinking Lights or Beeps and takenote of their pattern (1 Long or 1 Long followed by 2 Short).

Maybe your power cord is bad if you don't get anything to happen whatsoeverwhen you press the power button. And if that's true maybe you wasoperating off the battery the last time you had it on and since the power cordis bad, it was not charging the battery so the battery is drained and the powercord is bad.

Maybe you have a Static Charge Buildup. Remove the Power Cord, Remove theBattery, then Press and Hold the power button for 30seconds. After 30 seconds plug the power cord back in (leave the batteryout) and hit the power button to see if it boots. If it does, you can putthe battery back in and let it charge.Maybe your DC Power Jack which is where the power cord plugsinto the computer is bad. Take an ink pen and push the tip inside thejack and see if the little pin wiggles, if so the jack is bad. You'll have totake the laptop apart to fix it. Most times it is soldered onto themotherboard, so you will have to desolder the old and solder a new one.Maybe your memory is bad or the memory slot is bad.Remove the Power Cord, Remove the Battery, Remove the cover that houses the memory on the bottom of the laptop then remove one of thememory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x onit with an ink pen. If it fails to boot then move the chip to the nextmemory slot and try rebooting. If it fails take the chip out and set itaside, then put the other chip in and try booting it in both slots. If itboots, just to verify that the chip set aside is bad, mark an x on it and putit into the open memory chip slot and try booting.

Hi,
Considering the change in time and date,I would suggest you replace the CMOS battery.This battery helps in memory storage of your PC.
Have you tried the charger on another PC maybe?Try it,and if it fails replace it.
Remove the hard disk and re-fix it again.

Hope this helps.Thanks!

Have you tried to remove the battery and put it back in and try to turn it on. Try removing the battery and putting the charger in and starting the PSP. If it starts, it might be the battery. If it doesn't, it's either the plugin for the charger or the PSP is just dead. If it does start with the charger, try putting the battery back in, if it charges awesome. If it doesn't the battery might be dead.

remove charger,
remove battery

press and hold the power on button for 1min

place battery

press power on button,

if it doesnt light up, then check your memories chips. try another one

good luck

Why not look in the manual to see if there are any settings you have inadvertently changed ? BTW, you don't need a tall building - knocking it off a table would probably have the same effect.

The battery is worn out - replace it.

Sounds like a memory card problem. Try using A 512mb San Disk SD Card. Not a San Disk SDHC card. see if that doesn;t help you out. Good-Luck

Hi there please follow the steps and let me know the result.
1. Ensure batteries are fully charged & clean the battery connector point in side the battery compartment.
2. Look carefully between the lens and the camera body for any sand, dirt or any damaged etc.
3. Try turning the camera with the lens facing down and shake to dislodge anything stuck
4. Try removing batteries and memory card, wait 5 minutes and refit the battery only.
5. Now turn on camera( with out card ) and see ,if working then fix the memory card & again turn on the camera. If working then fine . Otherwise format the memory card and fix back in camera again & try. Make sure before format the memory card take a back up all photos in your computer then format. If no luck then reset or restore the camera setting by pressing Menu key for 2 sec .. in not done the press both Menu & self time key for 2 - 4 sec.
i hope it will gives you success. Thanks & Before you leave, if you have found my information helpful and if you haven't already done so then please press the ACCEPT button, this is how I am paid for helping you today. POSITIVE feedback & bonus is appreciated

Consider NOT connecting your camera to your computer.

The best way to download pictures from your camera to your computer involves removing the memory card from the camera and plugging it into a card reader (either built-in to the computer or connected via USB or FireWire). This is likely to be faster than connecting the camera to the computer, and won't run down your camera's batteries.

Once the card is plugged in, it will appear to your computer as a removable drive. You can use the operating system's drag&drop facility to copy pictures from the card to the computer's hard drive, the same way you copy any other files. Or you can use any photo cataloging program.

The camera does some digital noise reduction, to reduce the 'grain' effect when light is low. To avoid the delay (and seeing that message) take photos with more light - e.g. turn on the flash. This is a known annoyance with this camera - it would have been better to offer the option to turn this feature off, and de-noise the picture later on a computer; but it doesn't.
