Lost block adapter

[LadybirdBeebles]

My Stream 11 has been lost in one of my many boxes for a very long time. 

In many moves over the years I have lost the charging block/adapter, I was curious to know if there was a specific part number I needed or if it was even atill sold??

Hi:

Below is the link to the parts list for your notebook.

You need these part #'s:

741727-001

Smart AC power adapter (45 watt) - 4.5mm barrel connector, non-power factor correcting (NPFC) - Requires 3-wire AC power cord with C5 connector

L19367-001

Power cord - C5 connector, 1.0m long, STK Conv (North America)

What I suggest you do is to go on eBay, search by the power adapter part number and find a used but tested and working genuine HP power adapter.  Those usually also come with the power cords too.
