Interface (connectors): Parallel ATA a.k.a. IDE, ATA, ATAPI, UDMA and PATA — legacy, wide 40-pin connector for disks produced few years ago. In case of notebook drives pins are smaller, and there is also power supply in the same plug. Serial ATA (SATA) — modern connector. Most modern laptops use it. 6 data pins and 15 pins including power ...

The problem is that allowing people do unpaid overtime on their own kit is very cheap, so managers aren't so willing to stop it; but will of course be happy to blame IT when there's a leak... Only a strongly enforced policy is going to prevent this. It's down to management where they want to strike the balance, but it's very much a people problem. I've ...

I only recently was working on this, and while I can't give you an answer, I can give some observations: For $500 you won't get much of a developer laptop - $500 will get you a consumer laptop from BestBuy (or Dell if you order online). If that really is your budget all I can recommend is to look at the specs and try and fill the following which are in ...

Are you looking for something like this? http://www.microsoft.com/windowsxp/using/networking/setup/adhoc.mspx It's called Ad-Hoc wireless networking and it can be used to connect PCs to each other (and to the internet via ICS) without a router.

Our company requires whole-disk encryption on all company-owned laptops. Sure, there's an overhead, but for most of our users this isn't an issue -- they're running web browsers and office suites. My MacBook is encrypted, and it hasn't really impacted things enough that I've noticed, even when running VMs under VirtualBox. For someone who spends much of ...

More RAM is the way to go. Running multiple applications, that extra RAM will do a lot more good than a faster HDD which is still physically restricted to it's single spindle. Once you run of RAM and the OS starts paging to the HDD, your system will crawl irregardless of how fast your HDD is.

Unfotunately, it seems that your battery has reached the end of it's life. See this article for guidelines on how to maintain lithium based batteries. Four main points from the article: Avoid frequent full discharges because this puts additional strain on the battery. Several partial discharges with frequent recharges are better for lithium-ion than ...

This is the eternal question, but there is only one simple answer: It is always the wrong time. Whenever you buy anything remotely technical (computers, cars, ...) you will always have the "new model" available relatively shortly after your purchase, or the prices just drop. However there is some "soft" advice: Do not buy the latest and greatest products, ...

Short answer: yes, this will damage your battery. Take it out for extended periods when it's not going to be used. Lithium Ion batteries (as in your laptop) have a pretty short life anyway. Even if you leave it sitting on a shelf, never used, within 5 years or so it will be useless (which is why I feel sorry for people who are buying the $100,000 Telsa car, ...

Check out ThinkWiki; it has SOOO much information on thinkpads and good configurations, etc. And I'd personally suggest a T-series thinkpad, just cause a bunch of my friends (and myself) have them, and Linux works incredibly well with them (after a bit of tuning, of course).

From a hardware perspective, there is no straightforward way to do that. The video ports on most laptops are outputs, not inputs, and you can't reverse that. The keyboard/mouse ports are inputs, not outputs. Most USB controllers inside your server and laptop will fight over devices connected to the same bus, so attaching them via a hub is also not ...

Laptops don't have multiple processors Laptops don't have 192+Gb of RAM Laptop CPUs are often low-power versions (both in terms of watts and processing power) Laptop CPUs often put themselves into low-power mode to conserve battery power Laptops don't have RAID disk systems Laptops don't have Fibre Channel HBAs Laptops don't have mutliple ethernet ports ...

I would focus less on the equipment itself, and more on the data involved. This will help avoid the problems you're running into now. You may not have the leverage to mandate policy on personally owned equipment. However, you had better have the leverage to mandate how company owned data is handled. Being a university, we have issues like this come up ...

ARM chips are RISC processors that were created by Acorn and the design is now owned by ARM Limited. They license the design out to manufactures to add on to their own chips to create “systems on a chip” that contain many feature on one chip, and with the ARM design are able to include the CPU as well. The ARM is very prevalent in low power embedded ...

A few things here: 1) Batteries last 2 years under the absolutely ideal conditions (a user who never leaves the computer plugged in for days on end, and who regularly fully discharges and recharges the battery). 2) No user has ever used a battery under ideal conditions. In my experience doing laptop repair and working with laptops, the batteries last 18 ...

We use TrueCrypt. For laptops we insist on a BIOS password as well.

Why stop at gigabit? This device allows you to connect a pci express 16x card using an external box and the laptop's expresscard/34 slot. Now you put a 10gig card with sfp+, like one of these, into that. While you're at it, grab a couple of passive fiber taps. Now you've got a box that allows you to snoop any link you may encounter short of a sonet link, ...

Yes, actually: see this USB-to-KVM thingie. It is rather expensive, but does exactly what you want. If it wasn't so pricey, I'd have one in my bag.

Others have already commented on the disadvantages. I'd like to say a few good things. Advantages to using laptops: Power backup - assuming that the batteries still work, they would provide a sort of built-in UPS for the servers. Lower power consumption - as you've already mentioned. Built in KVM - no need for external monitors/keyboards, assuming the ...

Its actually possible to Run ESX as a virtual machine on your laptop:-) See the PDF here (Run VMWare ESX 3.5 & ESXI on Server 2.0 link) Also here Ran pretty well on a Dell laptop - as long as the Processor has V enabled in the bios and is compatible

1.) Working remotely For developers, remote desktop is a very good solution unless 3D is required. The performance usually is good enough. In my eyes, remote desktop is even safer than VPN, because an unlocked notebook with VPN active allows quite a bit more than a view to a terminal server would. VPN should only be given to people who can prove they ...

You'll have to gauge this for yourself, but in general I answer Yes to this question. The level of security measures you implement is largely about how much risk you are willing to assume. You have the financial risk of losing assets, as you've mentioned, and also the risk of losing data. If you are unwilling to accept that risk then yes, they should be ...

You asked how to shop for notebook hard drives. I prefer to hit my favorite review sites and look in their storage review sections. One of these always seems to have a good comparison review between hard drive vendors: TomsHardware storage section - most recent comparison is the 2.5" comparison charts. These are way too detailed, though. Anandtech ...

Factors affecting Li-Ion battery life: Everything I've read says that Li-Ion batteries last longest if they're kept cool and lightly cycled: run them down a little bit and then charge them. They basically have a fixed number of discharge/charge cycles, so keeping them plugged in most of the time is fine. I see 300-500 cycles mentioned frequently, one site ...

If you have an existing laptop, then you could consider a KVM2USB solution by Epiphan Systems. Although it is $399, you have to consider that purchasing some kind of "laptop kvm" type of device would probably be at least, if not more expensive. Consider how much rack mounted KVM displays go for.

Li-Ion degrades with use, so you should prefer shallow discharges. I.e., always charge it as soon as possible. This is in contrast to Ni-Cd and Ni-Mh accumulators, which do like to be fully discharged from time to time to keep their full performance. So normally you should plug in your laptop whenever possible. Another thing that is bad for Li-Ion is heat, ...

K-12 district here. We have 8 schools with 43 notebook carts (both 15 and 30 unit models) throughout the district. Buildings have [or will soon] eschewed traditional computers labs in favor of notebook carts. A couple things we've discovered over the years using these carts: 1. Standardize your notebook model. One of our earliest issues was the varying ...

If this was me, and you do not want a headache later... buy a second hard drive - 5400rpm's are around £30 for a cheap one or £50ish for a cheap 7200RPM and replace it with the one in the laptop. (edit - this assumes that the laptop is not running TPM / Bitlocker or anything where the machine is locked to using a single hard drive) This would be a easy swap ...

Having your "dropbox" folder encrypted is a good first step. I use a dedicated TrueCrypt partition for data, and use two passwords on the laptop -- one for Windows login, and another for the TrueCrypt data partition. One weakness here is that browser history, last opened file names, and many other potentially interesting kinds of user data are left ...

In practice your USB 2.0 interface will max out at around 30-40 MB/s. A single 10.000 rpm SATA 2 drive such as the WD Velociraptor will already saturate that connection. If you want to overcome the USB 2.0 bottleneck you can go for an eSATA ExpressCard. Models exist that have the RAID controller on the card. As for keeping it simple and compact you will ...
