Built for basic office use, it has a lot to offer, but is let down here by a significant design flaw.

HP: The Hewlett-Packard Company, founded 1935, commonly referred to as HP, is a technology corporation headquartered in California, United States. HP specializes in developing and manufacturing computing, storage, and networking hardware, software and services. Major product lines include personal computing devices, enterprise servers, related storage devices, as well as a diverse range of printers and other imaging products. Other product lines, including electronic test equipment and systems, medical electronic equipment, solid state components and instrumentation for chemical analysis. HP posted US $91.7 billion in annual revenue in 2006, making it the world's largest technology vendor in terms of sales. In 2007 the revenue was $104 billion, making HP the first IT company in history to report revenues exceeding $100 billion.
Up to 2015, the company was named Hewlett Packard Company. After a split, the computer range was renamed to HP Inc.
In the laptop segment, HP was the world's largest manufacturer from 2014 to 2016 with a market share of 20-21% from 2014 to 2016, but they only exceed Lenovo by a small margin as of recently. HP is not present in the smartphone sector (as of 2016).
Only some 3D games with very low demands are playable with these cards.
Intel Graphics Media Accelerator (GMA) 4500MHD: Onboard (shared Memory) GPU built in the GM45, GE45 and GS45 chipset (Montevina). Because of two more shaders and a higher core clock, much faster than the old GMA X3100. Still not advisable for gamers (DirectX 10 games not playable or only with very low settings). The integrated video processor is able to help decode HD videos (AVC/VC-2/MPEG2) , e.g., for a fluent Blu-Ray playback with slow CPUs.
Intel Graphics Media Accelerator (GMA) 4500M: The graphics core of the Intel GL40 and GS40 chipset features a slower clocked GMA 4500MHD (400 versus 533 MHz). Because of the slower core speed, full Blu-Ray Logo support is not given and the gaming performance is a bit worse.

Intel Core 2 Duo: This is the Core Duo and Core Solo successor with a longer pipeline and 5-20% more speed without more power consumption. As an addition to the Core Duo design there exists a fourth decoder, an amplified SSE-unit and an additional arithmetical logical unit (ALU).
The Core 2 Duo for laptops is identical to the desktop Core 2 Duo processors but the notebook-processors work with lower voltages (0.95 to 1188 Volt) and a lower Frontside bus clock (1066 vs 667 MHz). The performance of equally clocked notebooks is 20-25% lower than Desktop PCs because of the lower Frontside bus clock and the slower hard disks.
T6670: Entry level Core 2 Duo based on the Penryn core. Similar to the C2D T6600 but with VT-x Virtualization and higher temperature specification.
Intel Pentium Dual Core: The return of the name Pentium, though it is a Yonah core. In fact, it is a double Core processor with a very good relation of performance to current consumption.
T4500:
Entry to middle class dual core CPU with 1 MB level 2 cache and no virtualization technology. Compared to the Core 2 Duo line, some power saving mechanism are deactivated.
Intel Celeron M: It is a Pentium M with halved level 2 Cache and limited on FSB 400. The characteristic of this processor is the speed, which is hardly slower than an equivalent Pentium M. However it can change the speed not dynamically like the Pentium M and therefore needs without load more current.
It is also available as Low Voltage Version with very small current consumption.
900: Single core processor based on the Penryn core but many advanced features are deactivated. Due to the missing Speedstep, the CPU may lead to a lower battery runtime.

2.4 kg:
Usually subnotebooks, ultrabooks and quite lightweight laptops with 12-16 inch display-diagonal weigh as much.
2.5 kg:
62.67%: Such a bad rating is rare. There exist hardly any notebooks, which are rated worse.
