Unit has locked up.

i found this after a brief search

Straight from the service manual....just use the last 4 digits when doing a search, makes it easier to find the specific code as not all manuals are the same in how the code is displayed.

Boot into Safe Mode by pressing F8 during boot and...
Try disabling startup programs. Go to Start > Run (search in Win 7) and type MSConfig. In Startup tab, uncheck anything that you don't want Windows to load automatically. It will make Windows boot faster and use less resources while running. This just disables them in startup. Programs will still load, but when only you initiate.

HI. That code is in reference to the door locking mechanism. It is experiencing difficulties at this time. A Door Lock Error occurs if the door cannot be locked. It will try to lock it 6 times before displaying the error.

The necessary actions are to Check the wire harness connections to the Door Lock/Switch Assembly and Central Control Unit (CCU). This can be achieved by removing the top and front panel. The door assembly must be removed as well. Once you have exposed the door locking mechanism and its respective connections to the CCU, kindly, inspect each connections for a loose fit. The CCU will be located on the top of the unit, just to the rear or side of the interface panel. Check the linking connections that run to the door locking mechanism for a loose fit, as well. If all connections check out ok,simply, replace the door locking mechanism(switch assembly). This will correct the issue.

I have included a service manual for this unit. This duet service manual will guide you through the necessary disassembling process, as well as, the proper testing procedures for the door locking mechanism and CCU. The common fault here in your case will be a damaged door locking switch assembly, and replacing it will solve the problem. Click here to access your service manual.

Component accessing procedures will begin on page 4-1. The door switch assembly removal procedure will start on page 4-3. it is part of the door removal section. Follow it carefully to extract the assembly. Componet checks start on page 5-2. You can test the CCU door lock solenoids for proper ohms by referring to the ohm chart on page5-3. The CCU pin connector location is labeled on the top of page 5-1 under door lock solenoids. Due to the fact that there is a very small possibility that the CCU may be damaged, you can test the pins to verify that the CCU is indeed functioning with a good set of door lock/unlock solenoids. This will, essentially, isolate the door lock switch assembly as the lone culprit.

• Be sure to unplug the unit before attempting this repair and use caution.

This is a Hard Drive error. If your unit is under one year old, you can get the drive replaced by Dell.
The drive can be accessed outside the laptop to retrieve the data, but it may fail all together very soon.
If you have no data on it, just get a new Hard drive installed. Dell should be able to replace the drive and start the system restore for you.

I would recommend upgrading the E80 and the DSM to the newest software levels:

E80 - 5.52
DSM - 4.12.

You can download the software off raymarine.com and load them onto different compact flash cards. Both softwares are upgraded through the E80 display.

Page iv identifies the location of the scanner lock

Page 44 contains the following

• You unlock the scanner bed. For help locating the scanner lock, see the picture of the printer on page iv.

Page 51 contains

Unlock Scanner message
The scanner is locked. To unlock it:
1 Press Power to turn the printer off.
2 Use both hands to lift the printer (scanner unit) until the scanner support
holds it open.
To the left and beside the scanner support is the scanner lock. For help, see
page iv.
3 Pull the scanner lock toward you to unlock the scanner.
4 Using both hands, lift the printer (scanner unit).
5 Push and hold the scanner support back.
6 Lower the printer (scanner unit) until it is completely closed.
7 Press Power to turn the printer back on.

Hope it helps.

Without being about to do a HANDS on inspection of the laptop, it could have a couple of possible problems.

Here is my Best guess as to the probable cause. You have a loose/damaged connection on the Display screen. More than likely the power supply line to it. When it reboots it cools enough to pull away from its connection. Then gives you trouble rebooting until you apply and remove power several times. Why this is working by my theory is that each time you apply power it is sparking in that loose connection and slowly warming it back up until it finally connects again. Then all is fine until you reboot again and start the process all over.

This is a theory and I Can NOT guarantee that this is the problem. If it is. Then unless you are experienced at dealing with small electronics and high voltage. I would strongly recommend having it looked at by an experienced technician.

Sorry I couldn't be of more assistance

Purchased two of these VCR/DVD recorders (for the ATSC-digital tuner) in March 2007 at Best Buy. They play PAL/region 0 out of the box. To enable region-free playback I used the CD-ROM previously made for my LG LST-3510A. Visit this link for the files to burn your disc:

http://aiwaownersnetwork.tripod.com/pages/lg/5000_series_firmware.html

Next:
--Power on the player and load the CD-ROM
--In a few moments a text box appears displaying current DVD region and a second line to change DVD region
--Press the number you wish (most likely "0") on the remote control
--Press "Enter" on the remote control
--In a few seconds the player will eject the disc. Remove the CD-ROM from the tray and power off

Upon powering on the player my region 2 and 4 DVD's play fine but Macrovision still remains.
