Remember some while i posted about getting a third party universal power adapter for my conked out adapter for my Lenovo 3000 Y410, last week i got a nasty shock twice or thrice when i touched certain parts of my laptop. After testing it with a multimeter and tester, even though the output voltage was correct and my earthing system was ok the output power from the adapter is seemed to be AC power rather than DC power whereas the now replaced but still somewhat malfunctioning original AC adapter didn’t have this problem.

Huntkey power adapter

Next thing I went out bought a somewhat properly certified Universal Laptop power adapter from Huntkey matching my power requirements of 65W 19V, but this even though the power output matches the value it still shows current leaking out some metal parts of my laptop. I dont know whether the problem is related to the DC output or is it related to grounding the current (even though my grounding of the current seems fine)…

If you any ideas / thoughts please post your comments here…..

After a post on Laptop maintenance a while back, I thought of posting thoughts on protecting not only laptop but all electronic gadgets and gizmos from the main villain “Electric Power”. Even though these gadgets nowadays needs power and comes with inbuilt stabilizers and protectors I think the main source of motherboard problems in computers is due to lack of proper ‘grounding’ of electricity.

So I make sure a electrical technician has checked the power supply, grounding of my power supply and use a surge protector to make sure my laptop is protected from power surges and other power irregularities. And during lightning and rains, I make sure unplug the power cord and telephone cord too.Let me know your thoughts on this topic and post your comments here !!

When one of my friends was hunting for a netbook, I had suggested some options like netbooks from samsung like N120/N140, Acer Aspire One D250, Lenovo S10-2, HP Mini 210. But a friend who owns a network of electronic showrooms suggested Asus EeePC 1005HA for which he offered a good deal. Its specs at a glance,

  • Intel Atom N280 processor
  • 2GB DDR2 RAM
  • 250GB Hard Disk
  • 10.1″ Screen
  • Wireless LAN / Bluetooth
  • 0.3 MP Webcam
  • Card Reader
  • Windows 7 starter

asus eeepc 1005ha

This he gave at a price of Rs. 18,500/-(410 US$) which when compared to other models and retailers here was a good deal since it had according to me 2GB RAM to power Windows 7 and Asus was one of the first to bring netbooks and has quite a good reputation.

The black glossy finish and the overall sturdy finish was excellent to look and feel. And inside the keyboard was quite amply spaced and was ok to type at and the multi-touch touchpad was good too. The other thing which impressed me was the screen resolution 1024 x 600 which made viewing text a pleasure (as I’ve seen in some netbooks the font sizes being very tiny and makes our eyes squint). I think this was by some font sizer software provided by Asus. And there were some easy launcher tools by Asus for accessing settings, multimedia files.

It is supposed to have some power saving feature to power the netbook for almost 8 hours , so i think it should probably be good for 5-6 hours but it will depend on the usage.In my first test run the netbook was pretty nippy. As you can see from the photo, he also gave a Belkin netbook pouch for Rs. 600/-(13 US$) which was nice and handy to put the netbook (the netbook didn’t have any pouch / sleeve in its packing)

The 2nd year of my Ideapad didn’t have a auspicious start with my AC adapter conking out. Doubting whether warranty would cover it I was on the lookout for a AC adapter when I was given three choices – 1) Original Lenovo AC adapter – Rs. 1,500 2) OEM Lenovo AC adapter – Rs. 750/- 3) Universal Laptop power adapter – Rs. 650/-

Even though I was hesitant to buy a Universal power adapter main because whether it will be reliable and safe to my laptop, my fears were allayed by my friend so went ahead and bought it. I did my research on the net and found what size adapter pin is for my laptop and what were the power ratings.

As you can see from the above photo, that was the contents of the package. Even though the adapter box and the power plug doesn’t seem as solid as the original one. It was ok and there is a switch at the side to control the output voltage and a light at the top to indicate the output voltage. I think its safer to put a tape above the switch to avoid accidental changes. Moreover I tested it with a multimeter to check the actual voltage indicated is the output and it passed that test. So for almost a month now its been going without a hitch.

It seems it can fit multiple gadgets provided the pins (6 were in the set) and the output voltages matches the needs of your gadget. And it comes with a 6 month warranty.
