HP Pavilion dm4 laptop battery www.dearbattery.co.uk

The performance benchmark results with PCMark 8 were rather modest to say the least, clocking up 1389 in Home mode and 2378 in Work mode. Take the SSD away, and these figures could soon turn out to be quite alarming – I wonder how that HDD-equipped Acer Aspire V5-122P gets on?Talking of how things get on, tests with Linux were encouraging and disappointing in equal measure. I wonder how many commentards will have read this far before posting "Does it run Linux?", but I digress.I tried Ubuntu and Mint and both booted up into a command line interface. Mint went the extra mile suggesting there were problems with the graphics drivers, which is no doubt the cause, as there probably aren't any tweaks for the new Radeon HD 8250 yet. I'm sure it's only a matter of time.I started off liking the Samsung Ativ Book 9 Lite. Its plastic casing didn't bother me as I appreciated its light weight and slim form factor, carrying it around a lot and rarely running out of juice. The graphics performance was also pleasing, on the whole.

Even the vague suggestion that this laptop could be running a tablet chip didn't appear to be an encumbrance. Yes, I was prepared to be quite forgiving as I spent most of my time with it presuming it cost £400, which even then seemed a bit on the high side. It was only later I discovered its £500 pricetag, which rather took the shine off things for me. Surely, if you're touting a product as a Lite model, it really should be light on the wallet too – and especially so if you've something to hide. Nothing's perfect. The biggest omission is block-level replication. You can buy any two Sentinels and use DFSR to shuffle files back and forth between the two units. This turns your little RAID 5 into an effective RAID 51.It is an effective and functional technology; I've done this "hobo RAID 51" for over six years in dozens of SMBs using DFSR in every iteration from Server 2003 R2 through to Server 2012. It will handle tens of millions of files and hundreds of terabytes of data (though initial replication on that is…depressing.)

What DFSR won't do is replicate VHDs or VMDKs when they are being used as centralised storage for VMs. For that, you need Starwind.Starwind's iSCSI was included in the last Sentinel I reviewed. With Server 2012 R2 including a proven iSCSI target without requiring you to go download it, I guess it was felt that Starwind was unnecessary.DFSR will do for device redundancy on a filer. Cloud backups will do for disaster recovery, especially if you use something like Asigra and back up your clients to your own datacenter. It just doesn't cut the mustard when you want to use the thing for block storage.The new WD Sentinels are scrappy. I like 'em. When it comes to tossing a file server into a small business that will actually hit that filer hard I am going to have to give WD serious consideration.If I'm really lucky WD will start reaching out to Valley startups and start moving beyond Windows to address the growing use of virtualisation in the SMB world. Maybe a Nexenta-based Sentinel? Or working with a host-based caching company to jump the IOPS barrier?

The possibilities are endless, and WD seems open to exploring them. They've got good hardware engineers that actually understand things like thermal design considerations and that isn't to be overlooked. For better or worse, Western Digital are more than a disk peddler now. [1] While I used Unitrends for testing (they're who I'm familiar with), I should probably point out Arkeia, WD's recent backup acquisition. A little birdy informed me that there will be a lot of integration between the Sentinel and the Arkeia lines in the future.[2] I'd say sorry, WD, but you knew I was going to do this before you sent the thing to me.Will the next MacBook Pro refresh sport a 4K display, one 4,000-ish pixels wide? If Apple wants to ensure that its flagship laptop does indeed feature such a massive resolution screen, Sharp has just the LCD it needs.The panel pusher today said it is sending out samples of a 15.6-inch display with a 3840 × 2160 pixel resolution - 282 dots per inch, in other words. The “Retina display” MacBook Pro has a 15.4-inch screen with a 220dpi resolution.

The beta-test screen uses Sharp’s IGZO technology - IGZO being short for Indium Gallium Zinc Oxide. IGZO is an alternative to the amorphous silicon used to make the transistors embedded in most current LCD panels. Electrons can move more freely in an IGZO circuit than an amorphous silicon one.The upshot: displays made of IGZO transistors don’t have to be as thick as regular LCDs, allowing more light from the backlight to pass through, allowing you to fit a less bright and less power hungry backlight than traditional LCDs need.IGZO transistors can change state faster and don’t need as much power as conventional LCD components to maintain a static image, either.So far only pre-production samples are available, but Sharp said it expects to begin rolling the screens off the lines en mass at its Kameyama Plant No. 2 from February 2014.

Sharp has had more than its fair share of troubles of late and was last year forced to seek financial assistance from Taiwanese contract manufacturer Foxconn, which just so happens to be one of Apple’s key suppliers, though primarily for iDevices. Foxconn spent $800 million earlier this year on a 9.9 per cent stake in Sharp’s LCD factories.Something for the Weekend, Sir? Good news. A year on from the ICT debacle at my son’s school, he has ditched the joint and found another place where his skills are more appreciated.Faithful readers may remember - as for all you unfaithful readers, I understand the political parlance is to call you "sluts" - that a couple of days before he was due to embark upon that mighty educational experience and life-affirming struggle known as A Levels, the school decided that timetabling his ICT lessons was too complicated for them to be arsed with, and thus phoned up to tell him to pick another subject instead.

I don't mean to overrate my progeny’s affinity for computing but I remain shocked even now that his potential career in digital things could be dispensed with in such an off-hand manner by The Powers That Ought To Know Better. What if a spotty, teenaged Tim Berners-Lee had been told he had to drop Maths in favour of Home Economics, or a timetable cock-up had forced a youthful Stephen Hawking out of Physics and into Tap-Dancing classes?Just imagining a world in which Berners-Lee is a celebrity chef while Hawking is an X Factor judge is enough to make my head spin. What if Richard Dawkins had been bumped off the zoology course at Balliol College and sent to a seminary instead? What if Bill Gates had left school at 16 to get a labouring job on a road-digging crew? Oh, don’t tempt me.Inevitably, my son's first year in sixth form was a shambles, but as Manilow B (Yr 9) might have put it, he made it through the rain, and achieved the grades A C D C.With such auspicious grades, my son had no choice other than to land himself a place at the School of Rock. And so he did. He is now in Freshers' Week, which I imagine involves going to gigs around the town, carrying binoculars in order to get a better view of the lead guitarist’s chord sequences.

Upon securing his place at the end of the summer holidays, he received a congratulatory present to die for: my brother-in-law handed over a trunk containing his entire collection of several hundred audio CDs. It’s wide-ranging in style and all top-quality material. Several weeks later, we’re still looking at the jewel cases stacked up near the front door. Where the heck is he going to find the time to rip all those CDs? He did a few and then had to move on: this dude has other things on his mind, such as scales to practise, driving lessons to take and Steam updates to download.Personally, I like the idea of audio CDs in the same way that I liked vinyl albums and 45 RPM singles before them. Because they are physical objects you can pick up and throw around, you can share them very easily. When I buy music, I pay extra for the CD so that my wife and kids can pop it into the hi-fi when they like, and they do the same for me.

What CDs are rubbish at, though, are party playlists and personal stereos, but there you go. My view is that you can always rip a CD for personal use with a clear conscience, but copying your MP3s to lend to someone else feels exactly like the infant-slaughtering piracy that the law says it is.Back to the Manhattan skyline of CDs in their jewel cases at the front door, and we’re not sure how to tackle them. We now have so many CDs that finding the one you’re looking for is no longer an option. Years ago, my wife tried putting ours in alphabetic order in racks. Then I bought a new CD and put it in the wrong slot in the rack, causing a shift in the Earth’s axis, producing volcanic eruptions and plagues of locusts before triggering the End of Days itself.Up until this point, I was dismissive of seemingly pointless products such as digital jukeboxes like the Brennan JBs. Actually, I’m still dismissive: what are they for? Don’t answer, I already know. They are for fuddy duddies who don’t own a computer and therefore can’t make MP3s by themselves. Or maybe not. I just don’t understand them.

Perhaps what I need is one of those old multi-tray CD jukeboxes – not a Wurlitzer but those expensive things that we used to keep in the network backup storage cupboard back in the day – to load them and rip them ten at a time. Do these still exist? Can they be automated via iTunes? Have I nothing better to do than concern myself with this?My son probably wonders what I’m bothered about, since his smartphone can only hold about 4GB of music and he’s dropped it so many times that the headphone socket doesn’t work any more anyway.When he wants to listen to one of his uncle’s CDs, he goes to the front door to fetch it, takes it out of its case and puts it into his laptop. He feels absolutely no compulsion to devise devious ways of wasting a week of life filling fragile hard disk space with illegally produced MP3 files, some of which he may never ever listen to.
