ASUS 19-volt router power supply

03/01/2017 Leave a comment


A few days back, on the eve of the eve of the new year, one of my clients had a problem with their ASUS wireless router. So we took the router back to the office and  checked it. Router was fine but the power supply was dead. So I thought ok, no worries, let us get a compatible power supply and fix it. Then it hit me. Upon checking the dead power supply, I found out that the bloody thing was 19 volts DC.

I started to think to myself. Bloody hell. 19 volts? Where am I going to get an adapter like that? I had heaps of 12 volt DC power supplies and most of the Linksys routers (well, actually not all of them) take in a 12 volt power supply. The only power supply that give out 19 volts are the power supplies used by notebooks. How in the heck was I going to solve that?

So what I did was to come back home to check my spare parts box. I knew I had a spare power supply in there somewhere that I did not use anymore. So I took out an old HP one. Too bad. 20 volts. I took out an old Lenovo one but it was 18.5 volts. So I dug deeper and found an old ASUS one, rated at 19 volts. Where that one came from, I have no idea. I must have picked it up from somewhere. So I cut off the cable from the dead power supply and “grafted” it to the ASUS laptop power supply I found. Plugged it into the router and it worked a treat!

Moral of the story? Keep old junk. You never know when it might come in useful someday. As for ASUS, shame on you for making power adapters that break down like that.

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

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.

HP Pavilion dm4

21/01/2013 Leave a comment

I had the chance to use this PC the other day and I must admit that it feels pretty good. I have never been much of a fan of HP products but I can honestly tell you that this laptop feels good, and fast, It only had 2Gb of RAM loaded into it, with a 500Gb hard drive but the Windows 7 64-bit operating system felt zippy. I was thinking of looking for another PC for DJ’ing and this one came to mind. Specifications-wise, it has an Intel® Core™ i5-460M Processor Turbo Boost Technology. Not that update but fast enough. It can support a maximum of up to 8 GB DDR3 memory. The one I played with only had 2Gb and it was plenty fast! Storage-wise, it comes with a 640 GB SATA Hard Disk Drive. The one I played with only had 500Gb but that is a lot of storage space, considering the fact that my own personal computer only has a 320Gb hard drive!  It does not have a dedicated graphic card but the usual Intel® HD Graphics shared memory. I suppose if one puts in lots of RAM, it should take care of that.

Great laptop. If anyone sells it, I might take up their offer.

HP Mini netbook

09/09/2012 Leave a comment

Imagine. When these HP Minis first came out, I was very hesitant to buy one, even though many of my friends were saying that it would be a very good buy. I am now kicking myself for not getting one. Why you may ask. To put it simply, I have finally had the chance to try it out. Yes…three years after they made their debut I am trying one of them out and it is a lovely machine. It just works and performs marvellously, running on Microsoft Windows XP.

First off, it is a netbook, running on an Atom processor, to be precise, a 1.60 GHz Intel Atom N270 unit. Secondly, it only has 1Gb of RAM, but you can bump it up to 2Gb and that is the highest that it can go. It comes with an 80Gb 1.8″ hard disk drive so that is the Achilles heel of this laptop…the drive is not upgrade friendly. It will be very difficult to find a drive that size to replace it with when it goes. Maybe that is the reason that put me off this HP Mini. I know something put me off. But still, a nice and light netbook would do wonders for my aching back, toting this 15″ Dell Inspiron N5050 around.

Tablets have come to replace netbooks but for DJ’ing applications, these cannot be beat. I did not know back in 2009 that I would be requiring a notebook to mix in the future. Now I know that for a fact. OK…the hunt for an ideal laptop is on, once again.
