Laptop board repair

We fix more than Macbooks! Asus, Acer, HP, Dell, Lenovo – we bring these back to life every day. And cheap, too! Normally, it’s just a simple short on a power rail, a failed FET, a bad capactitor and/or liquid damage. Same stuff.

Most recent repairs include;

  • A Dell and an Asus needed sneaky naughty capacitor replaced. Maybe a new FET. Parts we have in stock. Cheap parts, just a matter of diagnostics.

Out the door, running again for $140 with 90 day warranty.

 

  • A Toshiba with a charred shorted area where DC Power-In jack solders to the board.

It was obvious what the problem was. The remedy was an entirely different issue; It shorted for a reason! Diagnosis found manufacturing defect that lead to eventual short of copper layers inside board substrate. Thermal image verified charred region as suspect area. My dremel tool was used to grind away that area until + and – read a  much higher resistance. Into the kOhms…that looks good. I conformal coated and corona doped the ground away area to protect them from future damage and to KEEP them separated (gotta keep ’em separated), rebuilt power and ground planes up, soldered new port on; it works. NEXT!

$140 – 90 day warranty

  • A common laptop issue; The center pin on the DC-in power jack cracked! I see this alot. Why does it crack? At the strangest place, too. Stress, strain. The DC-in jack build is flimsy. I soldered some of my desoldering braid across this crack. this will allow some movement and not crack ever again without transferring undue new strain forces onto the circuit board through-hole pad. This was a remedy that shows an appreciation of what happened. A real fix that addresses and solves the problem instead of just putting a band-aid onto the effects of the problem. Better than a mindless replacement of the DC-in jack with the same OEM time-bomb trap built-in. THAT’S a service.

I charged the customer $70 and gave 90 day warranty.

Macbook repair

 

This is important. Battery not charging is a common fault. Sometimes it is a bad battery. Most of the time liquid damage has done its damage. The SMC must see proper battery present, battery charge control IC is a middle-man in this communication channel. If I find these signals at the battery – it proves all.

Check battery charge data line;

I like Pomona test leads, There is no such thing as a good CHEAP bench meter. It’s my livelihood – this Keithley 2001 is a good one for me. Doesn’t fall into battery saver auto-off in the middle of chasing down a problem…got enough on my mind at such a time…Multimeter_ON

Ahhh – the TPS51125 IC chip. It should give your macbook board the 3.3V and 5V it needs. The 3.3V is *so* important…This is what we need for the power button to work.
