Description

CROSS-REFERENCE TO RELATED APPLICATION This is a continuation application of and claims the priority benefit of U.S. application Ser. No. 18/624,005, filed on Apr. 1, 2024, which claims the priority benefit of Taiwan application serial no. 112141306, filed on Oct. 27, 2023. The entirety of each of the above-mentioned patent applications is hereby incorporated by reference herein and made a part of this specification. BACKGROUND OF THE INVENTION Field of the Invention The invention relates to a laptop computer. Description of Related Art ESG is the abbreviation of three English words, namely Environment, Social, and Governance. The United Nations Global Compact first proposed the concept of ESG in 2004, and it is regarded as an indicator for evaluating a company's operations. ESG is a measure of a company's sustainable development indicators, which are the carbon reduction and sustainable development goals desired by international and domestic governments. In the past, business operations only needed to pay attention to financial data. However, even if the financial reports are promising, if the operations violated human rights, discharged wastewater, infringed on the rights of consumers, and harmed the living environment of the Earth's creatures, the international goal of promoting earth sustainability is violated, prompting institutional investors to reduce investment and cooperation in such companies, and even affecting the company's reputation. Today, companies that value the ESG concept not only have transparent financial reports, but also have stable, low-risk operating models, and their long-term performance is also relatively stable. For the above reasons, for the electronics manufacturing industry, whether the products manufactured thereby may meet the above conditions has become one of the product evaluation conditions. Taking laptop computers as an example, the evaluation content thereof is based on the amount of energy consumed in the manufacturing process of the product and whether the product has the ability to be repaired (renewed). In order to achieve the above goals, the member design and assembly configuration of laptop computers require corresponding new techniques and measures. In terms of assembly and configuration, the assembly process of existing laptop computers includes the positioning and buckling of tenons or hooks, the welding of members or electronic elements, screw locking and fixing, and the docking of related electrical conducting members (connectors, cables, or wires, FPC). . . . etc. In addition to the high complexity of the process, related accessories and consumables often do not meet the above sustainability conditions. Especially for subsequent maintenance and disassembly, the relevant connection ports or connectors of the members are readily covered due to stacking, making it unlikely for the operator to readily disassemble and assemble the members. At the same time, the electrical connection relationship between members also needs to be taken into account. Due to the complexity of electrical conducting members between existing electronic members, during the assembly process of the members, in addition to performing wire management operations, the operator also needs to worry about accidents such as misconnection of connectors. In addition, after the assembly is completed, there may be situations such as members being separated due to vibration or falling, etc., or the electrical conducting members falling off. Based on the above, based on the configuration and connection relationship of existing electronic members in laptop computers, the above sustainability goals are not readily met. SUMMARY OF THE INVENTION The invention provides a laptop computer, in which electrical connections are completed during the structural assembly process via a stacked structure of combined circuit boards and via an intuitive assembly method. A laptop computer of the invention includes a first casing, a first sub-circuit board, an input module, a second casing, a motherboard, and a bridge circuit board. The first sub-circuit board is disposed at the first casing. The input module is disposed at the first casing and electrically connected to the first sub-circuit board. The motherboard is disposed at the second casing. The first casing and the second casing are assembled together, such that the first sub-circuit board, the bridge circuit board, and the motherboard are partially overlapped, and the first sub-circuit board is electrically connected to the motherboard via the bridge circuit board. Based on the above, the member configuration of the system host of the laptop computer, especially the assembly configuration of the circuit board, matches the assembly method of the first casing and the second casing of the system host, and adopts stacked assembly to effectively simplify the assembly process, wherein the first casing and the keyboard, the touch panel, and the first sub-circuit board
