T520 DVD security retention screw.

My T520 didn't come with a DVD security retention screw. How do I get one?

Re: T520 DVD security retention screw.

I have a T510, and have never heard of such a screw. Where is it supposed to be located and what does it do?

Re: T520 DVD security retention screw.

It doesn't come with one AFAIK.

It's generally to prevent you from accidentally ejecting the UltraBay hard disk because you forgot about it and your OS is running off of it. Not as necessary with a DVD drive.

Re: T520 DVD security retention screw.

Thanks for that info. I use the Ultrabay III with the T510 just about all the time, but only as a data drive. I have to chuckle a bit that it is to prevent accidental release of the UB adapter. In order to release it, I have to disconnect all cables and turn the unit upside down to manipulate the release button and push the slider. :smileyhappy: I gather that the T520 is easier to release?

Re: T520 DVD security retention screw.

The new T520 is the same as on the W520.

It was a lot easier to eject it in UltraBays prior to the T510; flick the switch and pull the tab. I had a T400 and would absentmindedly fiddle with the eject tab. The redesign was probably to reduce that. :smileytongue:

Right. I also have a T60, and that has a very good mechanism - it popped out a pull tab - and you had to pull it. If you popped it out by mistake, you just shove it back in.

I am going to be putting a 1 TB drive in ultrabay securing the laptop with a kensinton cable but also need to secure drive with this screw. Any one have the part number.  The partnumber for T61 was 42W3824.

 

What is new part number.

IBM Parts, Lenovo Support, and Lenovo sales have no clue.

 

 

UPDate Found Part number!!!!!

UPDATE:   Shortly after I posted this, I found out that systems being built in June, 09 onward, we were eliminating this small bag of 2 screws from the ship group . We found that  few users actually used these screws.   This eliminated waste and reduced cost allowing us to be more competitive.  The amount saved was actually fairly significant, believe it or not.   For our more technical customers who would like to take advantage of this feature, I would recommend either ordering the assortment of service screws (FRU 42X4676 for T61 era systems or FRU 45N3853 for newer T400/T500/W500 systems).  These assortments are handy to have as they include spares of all the different screw types used in the system)
