Here are the system requirements:

• OS: Windows Vista, XP or 2000

• CPU: 3.0 GHz P4, Dual Core 2.0 or AMD64X2 (or higher)

• RAM: 1 GB for XP / 2GB for Vista

• DISC DRIVE: DVD-ROM Drive

• HARD DRIVE: At least 7.5 GB of free space

• VIDEO: Direct X 9 compatible video card (Video card must be 256 MB or more and should be a DirectX 9-compatible with support for pixel shader 2.0)

• SOUND: Direct X9.0c compatible sound card

The 945GM in your laptop does not meet the requirements to handle this game. The good news is that Left4Dead uses the Source engine which does not have very high video requirements which means that anything as like a nvidia 8600 or a ATI 36XX or newer should be able to handle this game without any problems.

Very doubtful. Not playable at least. Steam has a demo, just try playing the demo to see for sure.

FYI, 3d Gaming laptops that play stuff at a playable FPS are usually very expensive.

Maybe at lowest resolution.

yes it should be ok to run it becuase i have the same sort of pc and its ok
