Compaq Evo N1020v

MultiPort

MultiPort is an innovative feature created by Compaq. The idea was that it would use the MultiPort to connect to various expansion cards. The MultiPort used on the Evo N1020v used the USB 2.0 technology. This meant that, as though the notebook has no USB2 controller, and only supported the USB1.1 hub, the MutliPort was a separate technology altogether. There are three major variations of the cards that slot in; namely:

W200 - Wireless LAN (WLAN) 802.11b standard with 11 Mbit/s

W300 - Bluetooth standard with 2 Mbit/s

W400 - GPRS standard for worldwide communication

There are possible other versions which can be built customly on the technology.

Interfaces

The notebook conceals its interfaces behind a flap on the back. This means that the notebook has the following connections:

1x ECP/EPP IEEE1284 parallel port

1x PS/2 port

1x VGA D-Sub DB-15 connector

1x S-Video mini-Din connector

2x USB ports

1x IEEE1394 Firewire 400 connector

1x IrDA connector

1x MultiPort connector

1x Expansion port connector

1x RJ-11 modem jack

1x RJ-45 Ethernet jack

1x 3.5 mm line in

1x 3.5 mm line out

Internally, it contains:

1x mini-PCI

1x IDE hard drive controller and connector

1x Optical drive connector

1x Floppy Disk drive connector

These drives are "set-in-stone" drives and cannot be removed.

Upgrades

CPU and RAM The CPU can be upgraded in this desktop replacement system, but with great difficulty. A maximum of 2.4 GHz should be inserted, as the formula determines this:

where

P is power in watts

C is capacitance measured in farads

V is voltage measured in volts

f is frequency measured in hertz

The capacitance in the CPU is generally around 8.6 nF:

Maximum voltage (VCore) would be reduced to make up for the increase in power and the voltage is minimal as it is. Hence, the frequency increase to 3 GHz for instance, cannot be compensated by this notebook without further study. The maximum power usage of the CPU in this notebook is 56.5 W. This also requires a 90 W AC adapter. The CPU uses a Socket 478 connector.

The RAM can be upgraded to a maximum of 1024 MB or one gigabyte.

Wireless LAN Wireless LAN can be inserted via the expandable MultiPort or via the mini-PCI inside. This method requires the removal of the modem and the insertion of the card with two anntena (or three if using 802.11n). This can be a difficult process but when accomplished, it can work rather smoothly.

Hard disk drive

The backing storage of the initial 40 GB drive is usually insufficient. The drive may be upgraded to a 320 GB IDE drive. These can cost very little amounts.

Optical storage

One expandable upgrade to the drive is a CD-RW/DVD-ROM. This was as far as Compaq produced, but, others have dismantled other drives and formed DVD-RW drives for the notebook, some of which have Lightscribe.

Operating system

The notebook can operate Windows Vista, but it can do this only with great difficulty. As HP did not assign drivers to it for Windows Vista, the graphics card will not function and allow you to run Windows Aero.

Panasonic Tablet PCs Made For People On The Go

Panasonic Tablet PCs offer a range of features focused on specific users, all of them branded part of the Toughbook range. As the name suggests, the computers are built to survive rough treatment by people that require mobile computing because they often work out in the field.

All Toughbook models focus on providing clear display in daylight and protecting the most vulnerable components of a mobile computer, namely, the hard disk, keyboard and display panel. All units in the range can all go the distance when it comes to bumps, kicks and drops. They units fall into three groups; the Business Rugged, the Medical Rugged group and the All Rugged group.

Take the Business Rugged range for example. It includes two models, the CF-C1 and the CF-51. The CF-C1 is featured as the lightest 12.1 inch convertible tablet PC available on the planet. It weighs in at 1,470 grams (about 3.2 lbs) including one battery pack. Despite its lightness, the unit is no wimp. It is designed to withstand a liquid spillages all over the keyboard, high free-fall drops onto a hard floor and even a heavy klutz stepping all over it.

Inadvertent liquid spillages on a CF-52 will not damage the beast. The computer has a unique drainage system that protects the 87-key keyboard and touchpad. A full 170-milliliter glass can spill onto the unit and flow out through draining channels without damaging the computer. All electronics remain dry, unharmed and functional.

Drops and falls are a high probability event for mobile computers. When used in the field, they often accidentally get dropped or fall from their resting surface. Yachtsmen, for example, working at the navigation table of their pitching and rolling yacht know the agony of watching their notebook slide from the table and crash to the floor. The hard drive is very vulnerable to shock from a fall. Business Rugged Toughbooks can survive, hard 76cm falls without sustaining damage; in particular, the hard disk remaining safe and functioning.

The integrated Intel Core i5-520M processor delivers the highest calculating performance with highly efficient energy consumption. A lithium-ion battery provides up to 11 hours of operating time. The CF-31 also incorporates an anechoic chamber, being a non-echoing (or an-echoic) space designed to prevent reflection of electromagnetic waves. This design together with the dual diversity wireless antennae in the display housing combine to allow the CF-31 to deliver optimum data transfer and superior Wi-Fi Internet connectivity.

The CF-31 operating system is Microsoft Windows 7. The unit has a 160GB hard disk, 2GB main memory (DDR3 SDRAM) expandable to 8GB. Interfacing ability includes with four USB ports, one serial port, one modem port (RJ 11), one LAN port (RJ 45) and one external display port and one HDMI port (Type A).

In conclusion, Panasonic Tablet PCs offer style and functionality for mobile computer users. The CF-52 is a relatively high power consumer. It draws about 45 watts of power when operating and as much as 100 watts when recharging in ON state. The computer uses up to 0.7 watts of power even when it is on OFF state; this powers the computer internal clock.

should i upgrade my intel pentium 4 2.8 ghz cpu to a 3.4 ghz? help pls...?

Number of cores1 (max 1)
NameIntel Pentium 4
Codename Northwood
SpecificationIntel(R) Pentium(R) 4 CPU 2.80GHz
PackageSocket 478 mPGA (platform ID = 2h)
Rated Bus speed532.9 MHz
Stock frequency2800 MHz
Motherboard asus P4VP-MX

No! Why?
Because for one, the Pentium 4 at 3.4GHz is getting harder to find everyday. (Might be saying, "Ka-ching!" Like $$$$$$)
Two the performance increase is not worth it compared to what you can get now.

Comparison:
Let's compare an Intel Pentium 4, that operates at 3.2GHz, (Model 540J), to a small Intel Core2 Duo. The E4500.

The Model 540J, has ONE processor core that operates at 3.2GigaHertz.
It has 1MB of cache. (L2 cache)
It has an 800MegaHertz Front Side Bus.

The E4500 has TWO processor cores. EACH core operates at 2.2GHz.
It has 2MB's of cache. (L2 cache)
It also has an 800MHz FSB.

The E4500 is 40% faster than the Model 540J.

FORTY PERCENT!

Runs cooler, uses less power, and can kick a Model 540J to the curb.

Edit: Core2 Duo E4500

Even better for the money spent, and extra performance realized,

Mobo to run it that I would recommend? I base it on the
"Best Bang for the Buck" theory,
