How to Fix a Macbook Magsafe Charger (L Type)

IMG_1350My Macbook MagSafe charger for the past few months would occasionally stop charging. I would need to patiently wiggle the cord to a certain position to get it to start charging again. This is similar to the HP charger I issue I fixed several years ago.  I know from gut that there is a break inside the main magsafe and the cord. As I’m a DIY kinda of guy I’ve decided to fix it. Instead of buying a new charger of which will cost me $$.

Things you need to get this job done.

  • A pair of pliers,
  • thick cloth,
  • soldering iron,
  • soldering lead and
  • electrical tape.

Step 1: Wrap the pliers with cloth and clamp on the magnetic part and gently pull it from the body casing.
Step 2: Gently pull the innards out from the casing.

Step 3: Cut about an inch from the base.

Step 4: Unsolder from the base, if you can salvage those black shrinkage thing the better.

Step 5: Prepare the wiring then slightly cut the outer cover to reveal the wire and pull them aside. Then make another cut about a few cm on the inner cover to expose wiring.

15 - 7

Step 6: Push the insides back to the body casing and then start soldering back the base.

Step 7: Snap back the magnetic tip to the base. That should be it.

Transfer Analog MiniDV to a MacBook Pro with Firewire 800

If your like me who still uses an Analog miniDV to capture videos on special events, since early 2008 the MacBook Pro now uses a Firewire 800 and went away with the Firewire 400. You would need special cable or adapter to get the job done.

The last MacBook Pro I used which was issued to me when I was working for the local government was an older model around (2007) not the new unibody. Port available to me back then was the  Firewire 400.  The cable I used was a 4pin to 6 pin to convert my analog miniDV to digital.

Here is my Sony HC 32 cradle for my analog miniDV  where I hook up the 4 pin to the second slot marked DV.

So you can either get an adapter that converts Firewire 400 to Firewire 800.

Or  get a 4pin to 9 pin Firewire cable.

I got the 4pin to 9pin cable which cost P900( around $21-$22) in a store I found in SM Megamall.

Now I started to convert all those analog miniDVs I have collected and planning to get a digital camcorder in the future or a point and shoot camera that shoots HD videos.

Sun Broadband Wireless for reliable internet backup

Last week we moved to our new rented house from our old apartment. And with moving comes transferring of my PLDT DSL line which takes awhile. I have had my  Globe Tattoo kit since 2009 which I use for backups. I haven’t used it for exactly three months.  I was not thrilled when after hooking it up, it would connect but no webpages open, the download speed is 0.00. Also the I can’t register with it’s SUPERSURF50 promo. It would send but no reply.  I wasted alot of load trying to connect, disconnect.  I decided to do a quick search so I connected via 3G on my android phone and made a search, turns out there are alot of users having the same problem. It seems Globe’s network is congested as it gets. I called the tech number but no help. After reading which one among Globe Tattoo, Smartbro and Sun Broadband Wireless is the best. Sun Broadband Wireless stands out.

DIY: HP Laptop Power Adapter Repair

Got my wife one of those netbooks HP 2140 last year, the last couple of months it suddenly won’t turn on. The warranty was out and thought of the worst like motherboard failure etc.. Luckily it turns out the battery was drained and the power adapter was not working to charge it. After some googling it turns out this is common on HP laptop power adapters, there is a break going either on the pin side plug or the strain relief. So I was able to pinpoint the problem and just wiggled the strain relief and then taped it to position so it wont move that much. The strain relief is the rubber on the cable wire after the main power adapter box.  Tape fix was not elegant to look at but it worked.

Several days ago the HP netbook went dead again, power supply tape fix is not working anymore, exhausted trying to wiggle the strain relief and cable wire. Using another similar power adapter and netbook charged. So back to the power adapter problem I’m sure you can get a replacement for this online from $10-$25. But here in the Philippines maybe HP service center or distributor it’s pretty much around $20-30. But if your DIY like me, It was time to open it up look in the insides and repair it.

What I needed to do is cut the wires inside the strain relief,  remove the soldered wires, strip out portions of the longer wire to solder them back to board.

The tools I used were:
1. Hammer
2. Long flat knife
3. Cutter
4. Soldering Iron
5. Cable ties.

So first position the knife flat on the opening of side of the power adapter and slightly tap it going from base to up. This will open up the case instead of prying it open with a screwdriver. Do that on all sides then it would come off.

Next there is a metal sheet protector, remove them. On the bottom part it’s soldered to an IC. So heat it with a soldering iron and remember that extended IC as you will iron it back later. Now the strain relief is kinda messy, I had to cut it with a cutter to open it up then cut the wire. Next I unsoldered the portions of the wire connected on the board. Total there were three wires. First is the outer wire, white wire and the blue wire inside. So cut the wire and trim it the wires. Solder it on the same location as you did when you removed the old one.  Tape the remaining expose wires then  put back the strain relief.  Put back the sheet casing, iron the IC to the bottom part like earlier. Close the box and tie it with a zip a couple of cable ties to hold in place.

And there you have it, I managed to salvage the power adapter of my wife’s HP netbook.

PS. Pics are kinda blurry as I only took them with my phone’s cam. HTC Hero phone camera sucks at natural and low light! 🙁

Fixing power problems with your LG Flatron Monitor (LG1753S)

A couple of days ago during the weekend, I booted up my trusted pc lo and behold I heard the Windows startup sound but my LG monitor (LG1753S) screen is blank. I had this monitor for about 3 or 4 years now without any glitch. Used to leave it open for 72 hours sometimes. And this time it had failed to start up. So after checking the power is properly plugged, I shut down my pc again. Turned off the EPS and turn back on, the monitor power lit up(hooray?) but after a few seconds, its gone again.

So its final my LG screen is dead. After a couple of googling on my alternate internet device(HTC Hero), I found out it’s easy to fix. Thanks to this website for the amazing archive of fixing LCDs. http://www.ccl-la.com/blog/index.php/lg-l226wtq-bf-monitor-repair/. Just several capacitors failing me, being the jack of all trade that I am I decided I’ll fix it myself. I went to my trusted electronics shop and purchased some capacitors according to the article, but found out it wasn’t the right one. LOL. I opened up the monitor and upon inspection, the capacitor ratings are 4 1000uf 25v, 1 470uf 25v and 1 680uf 25v high temp. So back to the electronics shop. So after removing the old capacitors and soldering the new ones. The Monitor is good and alive again. Cost around $3 only for the whole thing.

Sorry for no pictures as the pictures got corrupted.

So a little bit of guts and the need to save on service fee, just DIY(Do-It-Yourself), make sure you have the right tools, a Phillips screwdriver, soldering iron, soldering lead and check the ratings of the capacitors before purchasing.
