[. . . ] PCM Upstream -- Increases the upstream data rates from the system to the ISP, which reduces the upload times for large files and e-mail attachments. A maximum upstream data rate of 48 Kbps is possible, compared to the previous V. 90 standard and maximum upstream data rates of 31. 2 Kbps. However, the PCM Upstream feature is ISP dependent. While PCM Upstream does increase upstream speeds, it also reduces download speeds at the same time. Because of this, Dell has disabled PCM Upstream on the computer. Modem-on-Hold The Modem-on-Hold (MOH) feature requires an applet to put the modem on hold to receive the incoming call or to place an outbound call on the other phone line. Modem-on-Hold is disabled by default. NOTE: MOH requires call waiting service from the phone company and V. 92 support from the ISP. V. 44 Compression V. 44 compression is a new ITU standard designed to improve data compression rates between the computer and the ISP. These higher compression rates, which increase between 20 and 60 percent on average and as much as 200 percent, mean more data can be downloaded in the same amount of time. Since HTML text files are highly compressible, you notice the most significant improvement when browsing and searching the Web.

As with all newly designed processors, these CPUs are not backwards compatible with older units. However, you can swap a single-core with a dual-core processor since they share the same socket design and pinouts. Unlike the newest desktop processors that use the Socket T design, the connector pins are not located on the system board but are still found on the processor itself. This design is more reliable for a mobile platform since the pins seat more securely. Take care not to bend the pins when removing or replacing a processor. For more information on these processors and their features, visit the "Processor Technology" section. Centrino Technology Centrino® has been around for several years and is Intel's complete wireless solution. Internet connections can be made with either wireless LAN or wireless WAN (cellular) cards. For a system to bear the Centrino Duo logo, the system must contain the following hardware: q q q Intel Core Duo processor Intel Napa chipset Intel wireless card Thermal Solution The thermal solution for the Latitude D620 is unique. In addition to a thermal pad that adheres to the bottom of the heat sink, an additional EMI pad covers the entire processor. Since the heat sink itself does not fully cover the CPU chip, this pad protrudes from the bottom of the heat sink. Additionally, the heat sink is different depending on the video solution of the system. The discrete version has a different design than the integrated solution, as seen below. Integrated Graphics Thermal Solution Discrete Graphics Thermal Solution Parts Replacement When the processor is sent for replacement, a heat sink is automatically included. Remove the protective backing that allows you to adhere the pad to the processor on the unit.

The Alps driver allows you to customize the touch pad and track stick's behavior. Biometric Reader The biometric reader on the Latitude D620 is optional, so not all systems have this device. It is located between the touch pad keys towards the front edge of the system. [. . . ] Next, it finds the INF file being used for the driver installation and verifies it was properly installed. Once this step is complete, Modem Helper checks if the associated COM port can be opened; if so, it tests the phone line for a dial tone. If it detects a dial tone, then the HTML screens instruct the customer to contact a DellTM Remote Technician if connectivity problems are being experienced. If no dial tone is found, the HTML screens notify the customer to run Modem Helper and display a hyperlink to start the diagnostic.
