Power adapter causing laptop to utilise 100% of CPU

06/03/2016 Leave a comment

 

I had a bit of a problem with my notebook the other day…and I could not explain why. It happened last week. I detached my laptop’s battery because I had fully charged it the night before. I then connected the power adapter on my desk to my laptop. When I turned on my laptop, it started to really lag. Thinking that I might have malware, I downloaded and installed the excellent MalwareBytes malware detector. The strange thing was that I detected no malware at all.

The next thing I did was to start up a free tool named Process Explorer. It too did not detect anything amiss. So here I was at wit’s end, wondering what in the world was causing this issue. I did not think much of it because I had to go off to a client’s place for a meeting and that was that. I packed up my laptop and left

Now while at my client’s place later that afternoon. I was thinking to myself if may laptop was screwed. But surprisingly, at my client’s place, when I started my laptop (I was using the fully-charged battery) all was fine! Laptop was as zippy as ever! So I was thinking it was an anomaly (I have learnt that Microsoft Windows has its quirks) and thought nothing more of it.

The next day, when I arrived at the office, I started up my laptop and noticed that I had only about 50% of my battery left. So I used it till it was about 10% in remaining charge before I plugged in my charger. Blow me down. Laptop started lagging…again! So I started thinking to myself and working it out logically what was causing the issue. When I started Task manager, it showed all four cores of my CPU at 100%. Then I started thinking…could it be the power adapter? So I unplugged the power adapter and would you believe ut? The CPU load went down! Bloody hell! So I unplugged my adapter, got in touch with my IT manager and asked him if he had one. he gave me another one and when I plugged in that one, I had no issues.

Was it really my adapter that caused that issue? Now, my instinct and logic tells me no. I mean, how could it? Maybe it is an older adapter with different voltage? All I know is my laptop was a HP and when I did a search on the Internet, lots of cases that echoed mine were HP laptops! Go figure!

Battery for my HP EliteBook 2560p

21/02/2016 Leave a comment

My office gave me this HP EliteBook 2560p and I am very happy with it. Ever since I changed to an SSD drive, I am even more happy with it. It does not matter that the size of the SSD is only 80Gb…it starts up in a flash (literally) and the battery lasts for quite some time. But there is a limit as to how long this battery lasts. So I am looking online for a battery to replace this one when it croaks. I have come across some compatible ones and indeed, I have bought some compatible batteries for my various mobile phones but batteries for laptops, they are a whole different story. I have heard some horror stories of batteries made in China that exploded and I cannot afford for that to happen. Just the other week, I had a power cable smoking and about to catch fire. I was lucky I spotted it in time or else I do not know what would happen. But the problem is that this notebook is an obsolete model so finding parts for it, in this case batteries, may be a bit of an uphill task.

HP EliteBook 2560p

23/09/2015 1 comment

My office gave me an “upgrade” of sorts, with this HP 2560p notebook. Now I am no stranger to the notebook because I used variants of this in my former company. It is a good, solid notebook that performs very well and has excellent battery life. This is what I got from HP’s website

HP EliteBook 2560p Notebook PC has 12.5-inch diagonal LED-backlit HD display with a choice of an Intel Core i7 or Core i5 standard voltage processor for maximum performance. It has been enabled with Intel vPro technology which repairs PCs over the network, even if a system’s Operating System (OS) is inoperable.

So far, i have had no issues with it. It comes shipped with 4Gb of RAM but the supplied operating system is Windows 7 32-bit. That in my eyes is a silly thing to do. Why would they do that? So when I got it, I brought it back home and reloaded it with Windows 7 Ultimate 64-bit. Now, it s able to take full advantage of the RAM on board and the ting just flies. From what I can see, HP did well with this notebook

Lenovo ThinkPad X61 CPU Fan and Heatsink FRU 41V9748 42X3804

07/04/2015 Leave a comment

Whenever I start up my trusty Lenovo X61 notebook computer, the fan always rattles. I have a feeling that the fan is coming to the end of its very long life. Trust me, when I say that this notebook fan has had a long life, I am not joking. In any case, I came across this fan and heatsink that was advertised on Ebay, costing about US$39. The advertisement claims that it is an original. But I found another online for almost half that price. They say that its a used one however. I have a decision to make now. I suppose I will have to change it and change it soon. I like this notebook. It is good and sturdy and that is one of the main reasons why I want to keep it, as “old” as it is.

Lenovo u330p laptop

14/10/2014 Leave a comment

 

My friend has this very same laptop that he uses to DJ in the pub that he is spinning at. This laptop is hooked up to a Pioneer DDJ-SB. The first time I saw it I was impressed. From the side profile, it looks lie a Macbook Air but that is where the similarity ends. Its a full-on PC running Windows 8.1, is endowed with a metal shell, a long-life battery and technologies like voice and motion control. Ports-wise, it has 1 USB 3.0, 2 USB 2.0, HDMI-out and a 2-in-1 card reader. For hard drives, you have a choice of:

  • Up to a terabyte of HDD storage – [500GB / 1TB (5400 rpm)]
  • Up to 500GB SSHD with integrated 8GB NAND flash (this is a hybrid drive)
  • Or up to 256GB SSD

I must admit that I love the laptop and its built to be prety sturdy. It costs about a thousand bucks here in Singapore. Not too expensive either.

HP Pavilion dv6 notebook computer

07/03/2014 Leave a comment

My workplace gave me this computer to use and I must admit, I like it. There is so much to learn in the world of computers nowadays that it almost seems that the moment you blink, you miss out on a lot of stuff coming your way. When I did a search on The Internet, I did not find much on the exact model of this notebook because there are so many variants of this. But I will tell you that it is pretty heavy, sports an Intel i& dual core processor and comes with 4Gb of DRAM in it. It also sports a 500Gb hard drive and has a very clear display. I use it with no issues at all and I must say that while it is heavy, it is a solid performer with excellent battery life. Yep…HP made a winner in this one.

Acer Aspire One AO756 notebook

04/09/2012 Leave a comment

Yet another notebook I came across in Comex 2012 a couple of days back is this one, for the low price of $499. It is the Acer Aspire One AO756. Pretty interesting notebook. Measuring 11.6″, it is more like a netbook but instead of an Atom processor, this comes with an Intel Celeron 877 Processor. Not too bad considering and pretty good in specs. It comes with Microsoft Windows 7 Home Premium and with 2Gb of RAM and a 500Gb hard drive. I figure that this would have been a great choice but I want to see if it is available at the next IT show in December. It is relatively small and unobtrusive and I think that it would be ideal for the job when I DJ. Specs-wise, from the Acer websiite:

  • Windows® 7 Home Premium – 64-bit version
  • Intel® Celeron® Processor 877 (1.4GHz, 2MB L3 cache)
  • 4GB DDR3 SDRAM
  • 500GB hard drive
  • 11.6″ HD Widescreen CineCrystal™ LCD display (1366 x 768)
  • Intel® HD Graphics – Mobile Intel® HM70 Express chipset
  • webcam
  • high-definition audio support
  • built-in stereo speakers
  • multi-gesture touchpad
  • 802.11b/g/n
  • 10/100 LAN
  • HDMI®
  • USB – 2-in-1 card reader
  • 4-cell battery
  • full-size Acer FineTip keyboard
  • 2-year limited warranty

Pretty good stuff at a pretty good price. I wonder if Virtual DJ will have problems with this notebook when hooked up too it? OK. I have the radar trained on this. Let’s see if it comes out again at the next IT show!
