AC Adapter for ThinkPad Edge 15

We lost the AC adapter for the computer. The Edge 15 Product ID is 0301JAU. I need to know the part number for the AC adapter and power cord. The battery is currently drained down. Googling for the info returns a lot of confusing info. The battery PN shows the following:

 

FRU P/N 42T4753

ASU P/N 42T 4754

 

From what I can determine, I think the adapter should be 20V 90W

 

Thanks

Hi bruce73 and welcome to the community,

 

Your voltage and wattage are right.  Here's a listing that shows all the models that the adapter will fit..

 

Here's your hardware maintenance manual .  On page 146 it lists the part numbers.

Re: AC Adapter for ThinkPad Edge 15

The Hardware Maintenance Manual lists four adapters for xxU (mine is JAU) on pages 146 and 147:
42T4427, 42T4431, 42T4435 and 42T4439

Reading from the manual, I went to the Lenovo Warranty Lookup for my machine ans serial number, and accessed Parts Lookup.

For MFG PN, FRU PN and Description it lists the following:

42T4418 42T4419 ADAPTER 2P

That 42T4419 seems to fit a sequence of numbering schemes for the adapter: 42T4419, skip 4, skip 4 again, then the 4427, 4431, 4435 and 4439 listed in the Hardware Manual. This is ambiguous as to which adapter P/N I need to buy.

Re: AC Adapter for ThinkPad Edge 15

I'm currently using a 92P1103 20V 90W adapter found on eBay using the search terms 'genuine thinkpad 90w adapter'. You might also try 'genuine lenovo 90W adapter' as these adapters are also used for lenovo's other notebook products.

 

Beware of cheap imitations, the ones I have bought have all been OK, both 65W and 90W.

 

I've just checked on eBay USA and immediately found two 42T4438 adapters, one for 16$.99 and the other for $26.88, both in the top half of a search for 'genuine lenovo 90W adapter'.

Re: AC Adapter for ThinkPad Edge 15

 

sgegreen is right, those adapters were used across a lot of lines of laptops. Different part numbers, same adapter.

 

It looks like your machine came with the 42T4419 which is a 60 watt adapter.  You'd be better off getting a 90watt adapter.  It will run cooler and probably last longer.

 

I'm running an X60T and the adapter part numbers are FRU 93P9026 and the part number is 92P1109.  This adapter will fit your machine also.

Re: AC Adapter for ThinkPad Edge 15

Thanks, guys. I'll go with the 90W adapter. The eBay link from Dave is a good price at $25 and free shipping. We will go ahead and order it as a spare, just in case even if the people at the facility where the presentation was given manage to find the original.
