1. This model is equipped with a keyboard lock feature; this can be mistaken as a no power condition. To unlock the keyboard press and hold the "menu" button on the front panel for 10 seconds. 2. (Power LED may be on after plug in) check for no less than 4.4 volts DC at pin 3 of PC9A21 on the Power PCB, if low or missing replace PC9A21 part # 268P058020.

Inspiron one 2305 will not come on. Tested adapter and it seems to have continuity but no power to system. No noise no screen nothing.

Hello ,
These all in one systems are similar to laptops because they use a laptop charger.and a laptop power adapter connection. Make sure to see if any lights light up to show if the system is receiving power.. If not then its either the dc connector that is on the system board. If your quite technical I always remove all components like the memory sticks,hard drive and dvd drive, then power the system back on just to make sure its the system board is not be shorted out.I like to rule all that out . Those system boards are not cheap. If your not that savy then just have a tech check it out.

My CD rom drive won't eject the cd on my Dell Studio Laptop. I press the eject button on the comp, and the click eject on the cd screen, and it makes a noise but nothing comes out.

You may have a cd jammed in your drive. Switch the computer off and on the front of the CD rom drive is a small hole, if you push a straightened paper clip quite hard into this hole it will open the drawer.

INTERIOR LIGHT AND CD PLAYER STAYS ON EVEN AFTER THE CAR IS SHUT

Sounds crazy but have your Alternator checked?
Sometimes things will act up in your car if your alternator is trying to quit on you!! happened to me.
i thought the mechanic was nuts but once it was changed everything went back to normal.

Drive is on, won't mount, buzzing

It does not sound good, the hard drive may be faulty or even the drive enclosure could be faulty.
Try thr following:-
1. Take the LaCie drive and connect it to another MAC, if it reads the drive, your in luck.
2. Dismantle the drive case and remove the hard drive and reconnect it again (a few times). The drive may need reseating to make proper electrical connection. Test it in your MAC.
3. The LaCie case could be faulty, remove the drive and insert it into another working LaCie drive case. Test it in your MAC.
4. If the hard drive is faulty, there are hard drive data recovery companies that can retrieve your data, but it will cost you an arm and a leg for their service.

In future I would not rely on a single device for backing up important data. You should get 2 LaCie drives or a dat tape drive plus a LaCie drive and/or burn the data on BlueRay disks.
You should also protect your computer and devices against lightning strikes, power outages/blackouts and power surges with an UPS (uninterruptable power supply), especially when you are editing, burning, copying/back up your data.

Computer powers on, but does nothing

Try putting your windows cd in before you boot up to see, when it starts up if your laptop is set up to boot from cd. If not, can you press F2 or DEL on boot up to see if you can enter the bios screen. Come back here.
