Acer um09g41 Battery

An Intel 2.2GHz dual-core Core i5-5200U Broadwell chip, HD 5500 GPU and 8GB of RAM give the Spectre a decent, albeit not out-of-the-ordinary performance. The benchmark test scores tell the same story. Averages of 2,400 and 2,650 on the PCMark8 Home and Work test runs were entirely unexceptional, as was the result of the 3DMark Skydiver test.The write speeds of the 256GB ADATA SSD averaged around 280MB/s, which was rather humdrum for this sort of money. That’s down to it being a SATA rather than PCIe affair. The average read speeds of between 500 and 550MB/s were better but still nothing to write home about. HP says this is down to cost. It reckons most punters would rather have a slightly slower 256GB drive than a slightly faster 128GB one for the same money.Another area where HP and MS swapped spit is the 802.11ac Wi-Fi radio, which apparently works over longer ranges with throughput not dropping off as quickly in either the 2.4GHz or 5GHz bands. While I’ve no idea if that’s true or not, what I can say is that wireless reception in my office, which is a bit of a black spot, was impressively reliable, so it appears there’s something in these claims.Battery life is a Spectre strong point, again due to some system fettling by the HP/MS team. This includes a more efficient (and quiet) fan and shutting down unnecessary parts of the system like the sensor in the hinge that works out what mode the Spectre is in; that does things like disable the keyboard. Apparently the Microsoft bods reckoned you can idle this sensor most of the time.HP also opted to remove all the status lights, so if you like your laptop to have a row of LEDs that light up like a Christmas tree when it does something, the Spectre may not be the machine for you. I’m told the Quad HD screen features something called Panel Self Refresh technology which avoids changing pixels unnecessarily to further reduce power draw.

The outcome of all that power saving is that HP reckons a full charge will get you through 12.5 hours. Looping a 1080p video using VLC with the display at three quarters brightness put the Spectre to sleep in 8 hours 15 minutes. That’s not bad and suggests the twelve and a half figure is achievable in mixed use. Spank the battery hard by running PCMark8 continuously and the lights go out after 5 hours 30 minutes.Like most thin 'n' light laptops, this isn't a machine you buy with the intention of taking it apart and rummaging around in its innards. Even with the Torx screws out, the back panel didn’t want to come off. The stereo speakers fire downward out of said panel and do a reasonable, if not spectacular, job. There is plenty of volume available, though.Microsoft's involvement in the development of the Spectre hasn’t resulted in anything spectacular but this is still a very smart and competent package. The impressive battery life, high quality keyboard, generous allocation of ports combined with a stylish design and high quality materials have resulted in a machine worth every penny of its £900 asking price.

I have a generic Windows 7 install, a lot of the modifier keys are non-functional, I also have a trial copy of MacDrive to read an external HD, but it asks for a serial every time I boot. Running Windows 7 on this machine is not atrocious, but some simple things seem to take forever.I've been flirting with Linux on virtual machines for years, dissuaded more than once by the appearance of Ubuntu, I stumbled upon Kali Linux, the deluxe penetration testing and hacking distro compiled by the macho sounding Offensive Security.Now I'm no great hacker, I lack that essential interest in other people’s business, but I do love sniffing Wi-Fi – we all have our little peccadilloes, you understand. It has saved the day more than once when the resident ISP goes titsup.Kali used to be called Backtrack but has since been Debianised and rebadged. To be frank, I don't understand a fraction of it, but am insatiably curious and away from my comfort zone is where I want to be.Apple gives you the illusion of understanding as England gives you the illusion of fair play. Both of my emigrations – home and computing – seem rooted in a desire to be out of my depth, or so it seems.Reckless by nature, I take the plunge. A bootable USB key drive and I'm away, the first moment of joy was upon being presented with a Macintosh keyboard layout option...as a typist I'm inept, but after two decades, my muscles must have retained some memory. The second moment arrived soon after, when my HFS+ external disk mounted on the desktop. The third moment took a while to sink in; no screen problems.Now Kali Linux includes just about every tool you need to snoop back from aircrack to metasploit, password crackers, everything you are ever likely to need to do something you shouldn't, but it includes next to nothing else.
