Power Consumption
As an ENERGY STAR partner, HP has determined that this product meets the ENERGY STAR guidelines
for energy efficiency (Windows 2000 only). This value is only achieved when “Suspend to RAM” (S3
mode) is enabled. To enable Suspend to RAM, enter the PC’s Setup program by pressing F2 during
startup and select the Power menu.
In normal mode power consumption will be around 50W.
NOTE The power consumption figures given in the table above are valid for the standard configuration as shipped. For more
information, refer to the product’s data sheet at HP’s web site: www.hp.com/go/desktops
When the computer is turned off with the power button on the front panel, the power consumption falls below 5W, but it
is not zero. The special on/off method used by these computers considerably extends the lifetime of the power supply. To
reach zero power consumption in “off” mode, either unplug the power outlet or use a power block with a switch.

System Features
20 Evo D310 Micro Desktop
Processor
The Compaq Evo D310 Micro Desktop is equipped with either a socket 478B
Intel Celeron or Pentium 4 processor. The processor is connected to the
system board through a Pin Grid Array (PGA) 478B Socket.
A heatsink and fan (not shown) cover the processor to prevent it from
overheating. If the heatsink is removed, the thermal interface material
between the heatsink and the processor must be replaced by a new one. If no
thermal interface is used or the old one is re-used, then cooling may be
impaired and the processor damaged.
Intel Pentium 4 (Socket 478)
The Intel Pentium 4 processor has the following features:
•Speeds ranging upto 2.4GHz
•Data bus frequency of 400MHz
•Dual Independent Bus architecture, which combines a dedicated 64-bit L2 cache bus (supporting
256KB or 512KB) plus a 64-bit system bus that enables multiple simultaneous transactions
•MMX2 technology, which gives higher performance for media, communications and 3D applications
•Dynamic execution to speed up software performance
•Internet Streaming SIMD Extensions 2 (SSE2) for enhanced floating point and 3D application
performance
•Uses multiple low-power states, such as AutoHALT, Stop-Grant, Sleep and Deep Sleep to conserve
power during idle times.
The Pentium 4 processor is packaged in a pin grid array (PGA) that fits into a PGA478B socket. The
Pentium 4 integrates the following cache memories on the same die as the processor cache:
•A trace instruction and L1 data cache. The trace cache is 4-way set associative
•A 256KB or 512KB L2 cache. The L2 cache is 8-way associative.
Intel Celeron (Socket 478)
The “new” Celeron (socket 478) processor is based on the Pentium 4 architecture. It is supported by the
Intel 845GL chipset. The “new” Celeron processor also features the following:
•Processor speeds ranging from 1.7 to 1.8GHz
•Front side bus 400MHz
•128K cache.
