If you are already aware of this, please ignore. I posted it because\nseveral people posting/lurking here are D5000 users.\n\nUpdated: August 12, 2009\n\nNotice to users of the Nikon D5000 Digital SLR Camera\n\nThank you for choosing Nikon for your imaging needs.\n\nWhile Nikon takes great measures to assure high quality in its imaging\nproducts, it has come to our attention that an electronic component\nrelated to power control in some Nikon D5000 digital SLR cameras does\nnot meet factory specifications and may, in certain circumstances,\nprevent the camera from turning on, thus preventing operation of the\ncamera.\nIndications of this issue include:\n\n1. The camera cannot be operated when the power switch is on, even\nwith a fully-charged battery.\n2. The camera cannot be operated with the EH-5a AC Adapter\nconnected through the EP-5 Power Connector and the power switch on.\n\nThe solution:\nNikon has isolated the issues related to this and has effectively\nresolved them. Preparations have been made at a special Nikon repair\nfacility to streamline the processes associated with the solution.\nService related to this issue, including the cost of shipping affected\nD5000 cameras to Nikon, as well as their return to customers, will be\nfree of charge. To further minimize customer inconvenience, Nikon will\nreturn serviced cameras to customers promptly, employing (whenever\npossible) transportation that limits transit time to two days.\n\nIs your D5000 affected by this Service Advisory?\nTo determine if your D5000 is affected by this Service Advisory, click\nthe Check Serial Number link below and enter your D5000 serial number\nwhere indicated.
