Backlight type of T400 2765-8JG

2014-08-14, 17:22 PM

Hello,

 

How can I guess what the backlight type of "Lenovo ThinkPad T400 - 2765-8JG" is? Is there any service url where I can enter the MPN or something else to look it up?

 

Thank you in advance.

Welcome to the forum!

 

Quickest way is to install HWInfo (Freeware) and check the model number of your panel, then google it to find out if it's a CCFL or LED.If you don't find anything post the model number here and we try to help.

Thank you for your prompt reply!

 

The problem is that I do not own the laptop yet I just plan to buy it. The current owner is not really into computers so I can't simply ask him to install some software and to check the part number for me. And because it is old laptop I suppose that the CCFL would be near the end of its lifespan so for me it is not wise to buy old CCFL-backlighted machine.

 

Perhaps there is another way to simply lookup by some number?

 

I'm not sure if this community is the right place to ask or maybe I should open new thread but perhaps any of you guys can recommend a better alternative for second hand Lenovo notebook?

 

Thank you.

Hello, and thank you for your input!

 

I can only guess that you got that data from the following URL:

 

http://support.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-t-series-laptops/thinkpad-t400/2765/8jg/documents/PD001345

 

I found that particular information about 2765-8JG earlier but I wasn't sure if it's not regarding new replacement parts. Indeed, according to the info there, all 2765-8Jx LCD displays should be with LED-backlight.

 

Can you just confirm that the information there is regarding the components during the time of manufacturing and not new replacement ones?

No, on the "old stile" support site. But information is the same.

Information about service parts, FRUs on support site is actual, for present time.

From time to time new parts appear and replace old ones, every part (new and old) has its own unique p/n (FRU). But if you see your laptop MTM in the service parts list, new parts are compatible with "old" laptop as well old parts were compatible before.

You might find compatible service parts list for your personal laptop and its parts if you know laptop serial number.

So, in other words, If I got you right, even if the listed LCD-LED panels are new replacements, it would mean that the old panel has to be LED too, because CCFL configuration would not be compatible with the LED configuration, right? I mean, for CCFL you need inverter, set of cables, maybe even the mobo is different, and for LED no inverter, different set of cables. It won't be possible to just unplug, plug and swap the different panels or am I wrong about that one?

I might be able to obtain the S/N, P/N, Manufacturer of the screen.

1. yes
2. different type panels are not interchangeable w/o additional parts you've mentioned as well as others - bezel, cover kit... I.e.different type panels need different laptop screen design and set of parts

- LCD panel, 14.1-in. WXGA+, LED backlight, FRU 42T0498 or 42T0504

Just out of curiositiy (not trying to be a smart@ss, I', just struggling a little with the new site) how did you manage to rule out the non LED options? If I check the current support site with the provided MTM number I also see the CCFL versions listed, like 42T0583, 42T0579 & 42T059

Tasurinchi,

you are right, there are FRUs for WXGA+ you've mentioned. But look at the page above (the link in the nightrider's post) or on the "old" site - only FRUs 42T0498 and 42T0504 matches MTM 2765-8JG (to be clear 2765-8Jx).
