It's a low-power (25W TDP) mobile Sempron 3000+ clocked at 1.80GHz with a 128KB L2-cache, 754-pin lidless package, 1.20V Vcore, 95°C max temp, revision DH-E6.
The correct part number is 'SMS3000BQX2
LF', not 'SMS3000BQXB
LF', by the way.
Unfortunately, specifications for AMD mobile parts (excluding older pre-K7 parts) are not publicly available at present.
This may change in the future, as AMD has recently published specifications for a couple (well, three models to be exact) Turion 64 MT-series processors.
Right now, however, you're out of luck if you're looking for AMD mobile specs on their official site (except Turion 64 MT-37, MT-34 and MT-32 models).
Now as for your upgrading plans, your Notebook should generally be able to accept any 754-pin mobile AMD processor with a 25W TDP, which means either low-power Semprons (fastest model is a 3300+ @ 2.0GHz/128K L2) or Turion 64 MT-series (fastest model is an MT-40 @ 2.2GHz/1MB L2) parts.
It depends pretty much on your machine's BIOS whether your new processor will be properly recognized, but since you already have a revision E part, your chances to get a Turion 64 MT-series part to work properly are pretty good in my opinion
To be on the safe side, I strongly recommend you ask your Notebook's manufacturer whether an upgrade is possible for you and if they can provide you with an upgraded BIOS-version (if needed).
Also, if you perform the upgrade yourself, your warranty may be affected (again, ask your manufacturer about this).
