HP Pavilion notebooks have always sounded great, so it’s not surprising that the hp pavilion zd7000 has the best sound of any notebook with a 17-inch screen we’ve tested so far. The integrated Harman/Kardon stereo speakers produce loud, clear audio from a panel that extends across the front; the setup is great for listening to music or watching a movie playing in the fixed DVD+RW drive located on the right side of the unit. The huge screen is impressive, with a standard native resolution of 1440 by 900 pixels. Aided by the top-notch GeForce FX Go 5600 graphics card and 128MB of graphics RAM, the display is sharp and easy to read and offers room for comfortably viewing multiple documents side by side.

Our review unit had the Windows Media Center upgrade ($175, included in our listed price), which comes with an external USB TV tuner and a remote control for recording and watching TV programs on your notebook. If there were a subwoofer (to fill out the bass) and a complete set of audio-control buttons on the notebook–all you get is a volume toggle at the top of the keyboard–the Zd7000 would be the perfect big-screen multimedia portable.

The model we tested also came with a preinstalled 802.11g Mini-PCI card. The laptop is ready to be connected to other devices too, sporting a whopping four USB ports (two more than usual) plus a FireWire port, an S-Video-out port, and two PC Card slots. The multimedia card reader located above the notebook’s infrared port on the right side can read SD/MMC, CompactFlash, SmartMedia, Memory Stick, and Memory Stick Pro cards.

Like most wide-screen notebooks, the hp pavilion Zd7000 is bulky and heavy. It measures almost 2 inches tall and weighs 9.3 pounds (11.1 pounds including the power adapter). Size has its advantages: The Zd7000’s expanded keyboard includes a separate numerical keypad, useful for people who work frequently with numbers. The extrawide metallic-skinned touchpad incorporates a textured vertical scroll zone and a handy lock button that prevents you from accidentally repositioning the cursor while typing. A presentation shortcut button not only launches a customizable presentation application but also stores a preset resolution (for an external monitor or projector) and power scheme.

But size does not always guarantee a better design. The Zd7000’s battery is one of the most difficult to remove that we’ve seen–we had to use the flat end of a screwdriver to pry open the bottom release. The big battery (one of the largest we’ve encountered) does not translate into long battery life, either, as the hp pavilion Zd7000 lasted only 1 hour, 48 minutes on one charge. However, since you’d likely have this hefty desktop replacement near an outlet all the time, battery life may be less of a concern.

Both the hard-drive and RAM slots are easy to reach in their compartments on the bottom of the notebook. Four small screws hold the panel covering the drive; RAM shares a cavernous compartment with the notebook’s wireless network Mini-PCI card.

The 2.8-GHz Pentium 4-equipped notebook earned a PC WorldBench 4 score of 110, about the same as results we’ve seen from similarly equipped systems running Windows XP Professional, but slower than the scores from systems using mobile Pentium M processors.

If the Zd7000 will be your primary PC, HP’s $249 Notebook Expansion Base could be a worthwhile addition (we didn’t test it). It includes built-in Altec Lansing speakers and serves both as a port replicator and as a stand to elevate the notebook screen to eye level. The notebook docks front-end first into an upright sleeve and connects via a proprietary connection located on the left side. Also included in the package are a wireless keyboard and a wireless mouse. HP Laptop Battery 

Home users looking for a desktop replacement that can double as a digital video recorder would like the HP Pavilion Zd7000; it would be ideal for college students who want both types of devices but have limited space. It is a heavy notebook with a weak battery, but these issues won’t be important if you stay put most of the time.

Many people find laptop shopping to be a bit of a chore. In previous years, the selections available would always leave one wanting more. This has changed in 2003 with Apple, Compaq, Dell, Toshiba, and IBM all producing svelte yet powerful laptops, making the past dreams of a true desktop replacement a reality. IBM T42

Excellent battery life usually is near the top of any list of must-have laptop features, with a good warranty a close second. My previous laptop had been a Gateway Solo 2500 which gave me about 3 hours of battery life when I first purchased it. The Solo 2500 also had a great warranty (which came in handy one more than one occasion). So with these requirements in mind, it was time to score a new portable. When the dust settled there was one laptop still standing: The IBM ThinkPad T40 Series. After reading about the prowess of its Pentium M CPU and excellent battery life, we were excited about buying ours and digging in. IBM ThinkPad T40

The laptop
We decided ultimately on the T40 2373-91u. The full specs on the machine are as follows:

Pentium M 1.6 Ghz
512 MB PC2100 DDR
Hitachi Deskstar 80GB, 4200rpm
14.1″ SXGA (1400×1050)
ATI Radeon Mobility 9000 / 32 Meg
Intel Pro1000 gigabit Ethernet chipset
56k V.92 modem
CD-RW/DVD Combo DRIVE IBM T40 
Usually the first remark you hear about the T40 is that it is built like a tank. Indeed, the rumors are true. While it is not completely indestructible, I have no fears about my T40 getting damaged in any minor calamity. While the lid gives a little when twisted, its magnesium alloy construction makes it nowhere near as malleable as the plastic on most laptops. The lid is attached to the base with two large metal hinges, and it would take a lot to break them off. The lid is also designed so its edges come around the base a little when it is closed. This provides a little more assurance against injury when you throw it in your bag.

All T40 models have dual USB 2.0 ports, S-video out, dual PCMCIA ports, and a parallel port. I would have loved to have seen FireWire standard on this notebook, but I don’t think the omission is anywhere near being a deal breaker. The other drawback to the T40 is that only one of the memory slots is user-accessible. So you might want to max out the base RAM when ordering.

As far as software goes, the T40 is light in that department. The laptop comes preinstalled with Windows XP SP1, Norton A/V (Trialware), IBM recordnow (a.k.a., Stomp Recordnow), and Acrobat Reader. Most of the other applications IBM included basically duplicate the functionality of other programs. One example is the IBM Update Connector, which updates drivers and IBM software. We could not think of a reason to use this instead of Windows Update. Another odd inclusion is IBM Access Support. This software includes a handful of diagnostics and troubleshooters for the computer, which do about the same thing as the troubleshooters in Windows Help. In general, Windows comes with better software to do the same things all of the IBM software does. Fortunately, you are in no way forced to use any of these utilities. At least IBM does not load the system with apps that just waste away in the system tray.92P1011 6600mAh

There was no media packaged with the laptop, so in the case of total hard drive disaster, you are required to call IBM. What you get instead is a restore partition on the hard drive. This makes it easier for a large company to deploy their own images for easy restoring, but to the average user it means you pay for 6GB of disk space you can’t use without reformatting. It also means that if you have a hard drive failure, you will be SOL. Fortunately, IBM will speedily send you a restore CD if you request one from tech support, or will send you a new hard drive if it is completely unusable. It would be nice if you could request to have it shipped with the computer.

One of the things to keep in mind about the ibm thinkpad t40 series t40 series is that it is designed in many ways for being deployed in droves across a large business. Features like Access IBM are more useful to large IT departments than to individuals who just want a laptop.

The ThinkPad comes with a standard three-year limited warranty, with a one-year warranty on the battery; pretty much standard issue. If you so desire, a more comprehensive warranty is available, which provides for next-day on-site repair. Past experience with the IBM warranty department has been pretty good, they are very hands-off, no off-base questions asked.
 

Specifications of MacBook as reviewed:

• 2.0GHz Intel Core 2 Duo
• 1GB memory
• 80GB hard drive
• Double-layer SuperDrive

Reasons for switching:

Apart from being greatly impressed by the OS X Operating System, I have recently been on the look out for a more portable notebook solution. After having ceased to play computer games due to excessive workload issues, I began to notice how big and heavy my 15.4 inch Asus A6Va really was. Also, as my university course has been focusing more and more on UNIX based systems in the past year and sensing that the trend is not going to change, I began to develop the need for a UNIX based Operating System. Linux, of course, would be an obvious solution, but I often find the popular Open Source Operating System act particularly unfriendly towards me.

Of course, friends are always a great factor in influencing my purchasing decisions. A number of them own MacBooks or iBooks, Macbook Pros, and Mac Minis. Although the Macbook Pro and the Mac Mini are both excellent machines, I did not quite like the Macbook Pro as I did not fancy the feel of its keyboard, and I do not see the point of spending a few hundred pounds extra for a dedicated graphics card I would never use. I did not like the Mac Mini because it meant that I would have to carry around a spare monitor. A1189

Feel free to contact me if you wish to hear all the other reasons that influenced my purchase decision.

Making the purchasing decision:

As a university student in the UK, I had access to discounts via the Apple Higher Education Store via the Apple website. Therefore, I decided to phone Apple and order through the phone to put their sales department to the test.

A cheery sounding sales person called Rod answered my call, who gave me the Higher Education discount after I told him I was from Imperial College. Note that the italic word does indeed mean what you think it means. I did not need to provide him with any proof of identity at all. But then again, I have heard that Apple do checks on the profiles of their customers during the few days before dispatch.

The Higher Education Discount meant that I only had to pay £755.50 for my MacBook as opposed to the usual price of £879. Other than the MacBook, I also ordered an HP Deskjet 5940 and the Brenthaven Edge 13.3″ Black Macbook case, which I might review at a future date if the demand for it arises.

The first information to provide would be the make and model of the equipment that you require the battery for, e.g.  HP F4098A Battery, or SONY PCGA-BPZ51 Battery . There is also usually a label on the battery, and some of the information on the label will help our sales team to identify your battery quickly. This information includes the voltage of the battery pack (note: this is not the same as the voltage on the power supply), the capacity of the battery pack and the chemical construction of the battery pack, e.g.Li-ion, Ni-MH or Ni-Cad. This information can be used to ensure the information you have provided matches the information we have about your battery. Many battery packs also have part numbers on the label; this can sometimes be used to help identify the battery. We would suggest that it is best to have all this information written down or close to hand before you call our sales team. This will help us deal with your call in an efficient manner.

In electronics, a battery is two or more electrochemical cells[1] connected in series which store chemical energy and make it available as electrical energy. Common usage has evolved to include a single electrical cell in the definition.[2] There are many types of electrochemical cells, including galvanic cells, electrolytic cells, fuel cells, flow cells and voltaic piles.[3] A battery’s characteristics may vary due to many factors including internal chemistry, current drain and temperature.

One common division of batteries distinguishes two types: primary (disposable) and secondary (rechargeable). Primary batteries are designed to be used once only because they use up their chemicals in an effectively irreversible reaction. Secondary batteries can be recharged because the chemical reactions they use are reversible; they are recharged by running a charging current through the battery, but in an opposite direction to the discharge current. Secondary, also called rechargeable batteries can be charged and discharged many times before wearing out. After wearing out some batteries can be recycled.  Laptop Battery

Although an early form of battery may have been used in antiquity, the modern development of batteries started with the Voltaic pile, invented by the Italian physicist Alessandro Volta in 1800. Since then, batteries have gained popularity as they became portable and useful for many purposes.[6] The widespread use of batteries has created many environmental concerns, such as toxic metal pollution.[7] Many reclamation companies recycle batteries to reduce the number of batteries going into landfills.

A camera is a device used to capture images, either as still photographs or as sequences of moving images (movies or videos). The term comes from the Latin camera obscura for “dark chamber” for an early mechanism of projecting images where an entire room functioned as a real-time imaging system; the modern camera evolved from the camera obscura.

Cameras may work with the light of the visible spectrum or with other portions of the electromagnetic spectrum. A camera generally consists of an enclosed hollow with an opening (aperture) at one end for light to enter, and a recording or viewing surface for capturing the light at the other end. Most cameras have a lens positioned in front of the camera’s opening to gather the incoming light and focus all or part of the image on the recording surface. The diameter of the aperture is often controlled by a diaphragm mechanism, but some cameras have a fixed-size aperture.  Camera Battery

The  Dreambox is a Linux-powered DVB satellite, terrestrial and cable digital television decoder (set-top box), produced by German multimedia vendor Dream Multimedia. Its firmware is officially user-upgradable, since it is a Linux-based computer, as opposed to third-party “patching” of alternate receivers. All units support Dream’s own DreamCrypt conditional access (CA) system, with software-emulated CA Modules (CAMs) available for many alternate CA systems. The Dreambox is based on the DBox2 units that were distributed by Kirch Media for its pay-TV services before its bankruptcy; it uses the same Linux-based software originally developed for the DBox2. The built-in Ethernet interface allows networked computers to access the recordings on the internal hard disks on some Dreambox models. It also enables the receiver to store digital copies of DVB transport streams on networked filesystems or broadcast the streams as IPTV to VideoLAN clients. Unlike many PC based PVR systems that use free-to-air type of DVB receiver cards, the built-in conditional access allows receiving and storing encrypted content.

The combination of third-party developers and network connectivity which facilitates card sharing, makes Dreambox use particularly common among enthusiasts and those who intend to obtain services without payment. Third-party software for this purpose is neither officially endorsed nor supported by Dream Multimedia and voids the official warranty; however, unofficial web sites support a very large community of enthusiasts.

In 2007, Dream Multimedia also introduced a non-Linux based Dreambox receiver, the DM100, their sole to date, running on unspecified hardware, but still featuring an Ethernet port and a USB port. [1] The speed of the USB port is not specified, the manufacturer only says it is of “B” type, the one found on peripherals connected to PCs.

The “Pandora’s Battery” as they call it, is just a regular PSP Battery . The battery of a psp has flash memory on it with boot information for the system. When converting the battery for this downgrade procedure, the psp program that you use actually dumps the batteries flash and puts a bin image with official sony firmware 1.50 and some developer code. When you place the converted battery into the psp it boots and runs the developer code and downgrades the psp. At this point, they say that the battery is useless. They have come out with an update that will convert the battery back and thats why they dump the flash first. After the psp is downgraded, if you use the converted “pandora battery” as your power source, it will only run a partial of the 1.50 firmware because of the missing battery flash files. in order to have full 1.50 you must convert your battery back into a normal one.

The reason a PSP running 1.50 or custom firmware is required to create a pandora’s battery is that you have to run some unsigned (i.e. homebrew) programs from the PSP itself to create the battery. Also, a memory stick pro duo is also required. Most people are suggesting to use a 256MB one, as it is the smallest pro duo you can get, plus it’s guaranteed to work on one that small. You can’t create a ‘jigstick’ (that’s what they call the memory stick that works with the battery) out of a 4GB or larger one. A jigstick will work as a normal memory stick, but you have to have a jigstick to use the pandora’s battery. Creating the jigstick is part of the process of creating the battery in the first place, so if you get a spare battery, a 256mb-2gb memory stick pro duo, and have access to a 1.5 or custom firmware PSP, just follow the instructions and you’re set.

On August 22, 2007, Team C+D released the “Pandora’s Battery” that can convert a spare Memory Stick Pro Duo and battery into a “Magic Memory Stick” and a “JigKick Battery”. The Memory Stick and the JigKick battery couple is called “Pandora’s Battery”. The Memory Stick and battery can then be used to downgrade any PSP of any version or to recover from a brick. To convert the Memory Stick and battery another PSP which is able to run 1.50 homebrew is needed. The Memory Stick can also be converted without using a homebrew PSP by using a Pandora’s battery program, such as Pandora Easy GUI. After the downgrade/unbrick service has been completed, the Memory Stick and battery can be restored for normal usage.

A “JigKick Battery” is a battery with the first adress in the EEPROM chip changed to 0xFFFFFFFF. This unlocks the service mode of the PSP and launches the IPL from the Memory Stick (instead of from flash0). A “Magic Memory Stick” consists of a reverse-engineered IPL and a minimal subset of the firmware 1.50 stored on a Memory Stick Pro Duo. This downgrader can downgrade all firmware versions. The original version is incompatible with the PSP Slim & Lite due to the 1.50 IPL being incompatible with PSP Slim & Lite hardware. However, on September 28, 2007, a version that works on both the old style PSP and the Slim & Lite was released. The new debricker is called Despertar del Cementerio, and is also known as the Universal Unbricker, which was developed by Dark_Alex. Instead of installing firmware version 1.50, it installs a custom firmware.(PSP Battery )

The “JigKick” battery can also be created by lifting the fifth pin of the EEPROM on the battery’s mainboard, circled here. This is somewhat dangerous because it disables the EEPROM entirely, and may have side effects such as overheating if pin 5 is shorted to other pins while desoldering.

The battery that is included with the PSP Slim can also be converted into a “Pandora” battery by using the hardware modification method mentioned above.

There is now a method that will enable users of custom firmware above 3.71 M33 which does not automatically have the 1.50 firmware kernel to create a Pandora battery. This method can be found here.

Though Sony advocates against use of any homebrew, representatives have said that the Pandora’s Battery will not physically harm the PSP in any manner, as this is the same method used by Sony when customers send in their bricked PSPs for repair.
