I am slowly beginning to hate Dell
Posted: 18 Apr 2013, 21:39
My laptop, which as you know is screamingly fast and VERY expensive, started becoming slower and slower. I knew I'd finally hit the limit of memory with my virtual machines and had to finally do the upgrade I always planned. My experience index (WEI) had dropped from 7.5 to 7.1 and I assumed it was down to the new drivers for the graphics card.
So I buy the newer, faster, memory for my laptop and fit it. Reset the WEI and tada, it's 4.7. WTF!!!!
After significant faffing around, I finally plugged in the original power adapter that came with the machine. Re ran the test and Hey Presto, back to a WEI of 7.5.
Now why did it do this?
A little known fact about Dell computers (Alienware is Dell), is that they put identifying chips in their power supply. The computer reads the chip on the power supply via the pin in the middle of the power plug and if it's not the one it wants it won't charge the battery. No real issue for me as I just run it at a lower charge. It still gives mains power and the battery doesn't discharge any more.
So far so good. Except that if the power is less than 100% and the laptop is not actively charging, then it starts to throttle back the CPU. As much as 45%. Killing performance and dropping the WEI.
I now have the original power supply in it again. But that weighs a good 3 kg and it's bigger than a house brick. Not very portable. Replacements are all the same size and weigh the same. Oh and they cost a minimum of £120 because Dell have a monopoly on the codes in the chips in the power supplies....
Not amused. I never wanted a Dell in the first place. The build quality is incredible but things like this just irritate the hell out of me.
Nice to have my machine report 9% memory usage when it starts up though. Instead of 40% or 50%. Of course with all the Virtual machines running that goes up to 45 - 50% but, still, that's fine.
SSD D drive next. But that's a different story. They are still £250 - £330.
