Installing and Replacing Desktop Board Components

Replacing the Battery

A coin-cell battery (CR2032) powers the real-time clock and CMOS memory. When the computer is not plugged into a wall socket, the battery has an estimated life of three years. When the computer is plugged in, the standby current from the power supply extends the life of the battery. The clock is accurate to ± 13 minutes/year at 25 ºC with 3.3 VSB applied.

When the voltage drops below a certain level, the BIOS Setup program settings stored in CMOS RAM (for example, the date and time) might not be accurate. Replace the battery with an equivalent one. Figure 25 on page 51 shows the location of the battery.

CAUTION

Risk of explosion if the battery is replaced with an incorrect type. Batteries should be recycled where possible. Disposal of used batteries must be in accordance with local environmental regulations.

PRÉCAUTION

Risque d'explosion si la pile usagée est remplacée par une pile de type incorrect. Les piles usagées doivent être recyclées dans la mesure du possible. La mise au rebut des piles usagées doit respecter les réglementations locales en vigueur en matière de protection de l'environnement.

FORHOLDSREGEL

Eksplosionsfare, hvis batteriet erstattes med et batteri af en forkert type. Batterier bør om muligt genbruges. Bortskaffelse af brugte batterier bør foregå i overensstemmelse med gældende miljølovgivning.

OBS!

Det kan oppstå eksplosjonsfare hvis batteriet skiftes ut med feil type. Brukte batterier bør kastes i henhold til gjeldende miljølovgivning.

VIKTIGT!

Risk för explosion om batteriet ersätts med felaktig batterityp. Batterier ska kasseras enligt de lokala miljövårdsbestämmelserna.

VARO

Räjähdysvaara, jos pariston tyyppi on väärä. Paristot on kierrätettävä, jos se on mahdollista. Käytetyt paristot on hävitettävä paikallisten ympäristömääräysten mukaisesti.

VORSICHT

Bei falschem Einsetzen einer neuen Batterie besteht Explosionsgefahr. Die Batterie darf nur durch denselben oder einen entsprechenden, vom Hersteller empfohlenen Batterietyp ersetzt werden. Entsorgen Sie verbrauchte Batterien den Anweisungen des Herstellers entsprechend.

D945GPM specifications

The Intel D945GPM is a motherboard that was designed primarily for desktop PCs and is part of Intel's 9-series chipset family. Launched in the mid-2000s, this motherboard has gained recognition for its robust performance and solid feature set for users seeking a stable and efficient computing platform.

One of the hallmark features of the D945GPM is its support for Intel's LGA 775 processor socket. This accommodates a variety of processors, including the Pentium 4, Pentium D, and the Core 2 Duo series. The motherboard supports dual-channel DDR2 memory, with a maximum capacity of 4GB, providing sufficient memory bandwidth for most basic computing tasks and multitasking needs.

The D945GPM is built on the Intel 945G chipset, which integrates the graphics controller, simplifying the motherboard's design and enhancing efficiency. The integrated Intel Graphics Media Accelerator 950 allows users to perform casual gaming, video playback, and standard office applications without the need for a discrete graphics card. However, for those requiring higher 3D performance, the motherboard includes a PCI Express x16 slot, enabling the installation of dedicated graphics cards.

Additionally, the D945GPM features several connectivity options. It includes support for up to four SATA 3.0 Gb/s connections, which allows users to connect multiple hard drives or SSDs for improved data transfer rates and storage capabilities. There are also four USB 2.0 ports available, providing connectivity for peripheral devices like keyboards, mice, and external storage.

The motherboard integrates an Intel High Definition Audio subsystem, delivering clear and crisp audio quality for an enhanced multimedia experience. The Realtek ALC888 audio codec contributes to decent sound performance for gaming, movie watching, and music playback.

User-friendly features include a BIOS that supports a wide range of customization options, allowing enthusiasts to tweak and optimize performance settings. The motherboard is also equipped with multiple fan headers, enabling efficient cooling setups to maintain stable operation during intensive tasks.

Overall, the Intel D945GPM motherboard stands out for its balance of performance, features, and reliability, making it an excellent choice for basic computing, light gaming, and media consumption, reflecting the tech standards of its time.
