Battery life
2nd October 2011
In recent times, I have lugged my Toshiba Equium with me while working away from home; I needed a full screen laptop of my own for attending to various things after work hours, so it needs to come with me. It's not the most portable of things with its weight and the lack of battery life. Now that I think of it, I reckon that it's more of a desktop PC replacement machine than a mobile workhorse. After all, it only lasts an hour on its own battery away from a power socket. Virgin Trains' tightness with such things on their Pendolino trains is another matter...
Unless my BlackBerry is discounted, battery life seems to be something with which I haven't had much luck because my Asus Eee PC isn't too brilliant either. Without decent power management, two hours of battery life appears to be as good as I get from it. However, three to four hours become possible with better power management software on board. That makes the netbook even more usable, though there are others out there offering longer battery life. Still, I am not tempted by these because the gadget works well enough for me that I don't need to wonder about how money I am spending on building a mobile computing collection.
While I am not keen on spending too much cash or having a collection of computers, the battery life situation with my Toshiba more than gives me pause for thought. The figures quoted for MacBooks had me looking at them, even if they aren't at all cheap. Curiosity about the world of the Mac may make them attractive to me, only for the prices to forestall that, and the concept was left on the shelf.
Recently, PC Pro ran a remarkably well-timed review of laptops offering long battery life (in issue 205). The minimum lifetime in this collection was over five hours, so the list of reviewed devices is an interesting one for me. In fact, it even may become a shortlist should I decide to spend money on buying a more portable laptop than the Toshiba that I already have. The seventeen-hour battery life for a Sony VAIO SB series sounds intriguing, even if you need to buy an accessory to gain this. That it does over seven hours without the extra battery slice makes it more than attractive anyway. The review was food for thought and should come in handy if I decide that money needs spending.
A useful little device
1st October 2011
Last weekend, I ran into quite a lot of bother with my wired broadband service. Eventually, after a few phone calls to my provider, it was traced to my local telephone exchange and took another few days before it finally got sorted. Before that, a new ADSL filter (from a nearby branch of Maplin as it happened) was needed because the old one didn't work with my phone. Without that, it wouldn't have been possible to debug what was happening with the broadband clashing with my phone with the way that I set up things. Resetting the router was next, and then there was a password change before the exchange was blamed. After all that, connectivity returned to allow me to upgrade in the middle of it all. Downloads are faster, and television viewing is a lot, lot smoother as well. Having seen fairly decent customer service throughout all this, I am planning to stick with my provider for a while longer, too.
Of course, this outage could have left me disconnected from the Internet but for the rise of mobile broadband. Working off dongles is all very fine until coverage lets you down, and that seems to be my experience with Vodafone at the moment. Another fly in the ointment was my having a locked down work laptop that didn't entertain such the software installation that is required for running these things, a not unexpected state of affairs, though it is possible to connect over wired and wireless networks using VPN. With my needing to work from home on Monday, I really had to get that computer online. Saturday evening saw me getting my Toshiba laptop online using mobile broadband and then setting up an ad hoc network using Windows 7 to hook up the work laptop. To my relief, that did the trick, but the next day saw me come across another option in Argos (the range of computing kit in there still continues to surprise me) that made life even easier.
While seeing if it was possible to connect a wired or wireless router to mobile broadband, I came across devices that both connected via the 3G network and acted as wireless routers too. Vodafone has an interesting option into which you can plug a standard mobile broadband dongle for the required functionality. For a while now, 3 has had its Mifi with the ability to connect to the mobile network and relay Wi-Fi signals too. Though it pioneered this as far as I know, others are following their lead, with T-Mobile offering something similar: its Wireless Pointer. Unsurprisingly, Vodafone has its own too, though I didn't find any mention of mobile Wi-Fi on the O2 website.
That trip into Argos resulted in a return home to find out more about the latter device before making a purchase. Having had a broadly positive experience of T-Mobile's network coverage, I was willing to go with it as long as it didn't need a dongle. The T-Mobile one that I have seems not to be working properly, so I needed to make sure that wasn't going to be a problem before I spent any money. When I brought home the Wireless Pointer, I swapped the SIM card from the dongle to get going without too much to do. Thankfully, the Wi-Fi is secured using WPA2 and the documentation tells you where to get the entry key. Having things secured like this means that someone cannot fritter away your monthly allowance as well, and that's as important for PAYG customers (like me) as much as those with a contract. Of course, eavesdropping is another possibility that also is made more difficult. So far, I have stuck with using it while plugged in to an electrical socket (USB computer connections are possible as well) but I need to check on the battery life too. Up to five devices can be connected by Wi-Fi, and I can vouch that working with two connected devices is more than a possibility. My main PC has acquired a Belkin Wi-Fi dongle to use the Wireless Pointer too, and that has worked very well too. In fact, I found that connectivity was independent of what operating system I used: Linux Mint, Ubuntu, Windows XP and Windows 7 all connected without any bother. The gadget fits in the palm of my hand too, so it hardly can be called large, yet it does what it sets out to do, and I have been glad to have it so far.
