My laptop will not charge my battery?

by

This section will try to answer the most often asked questions I get.

My laptop will not charge my battery?

This question gets asked quite often. In an older system the battery may be weak, and the cells have died which would require a new battery.

If your system has a loose jack, this would also cause your battery to power poorly. Simply unplug your battery, and try powering it on on straight DC power. If your power cable does not require handling to power on, your battery is bad or an internal fuse.

If you have a bad 2.5mm jack, I sell wiring harnesses to convert your 2.5mm or 1.65mm jack to a wired 2.5mm that mounts to the case lowering the risk of any future DC jack breaks.

Some systems also have internal ceramic fuses that are 10A, 12A, and 15A that may blow. These fuses are soldered directly to the motherboard.

What if my need is not listed?

As an electronics technician, laptops and desktops are not the only items I work on. If you have a specific need that is not isted above, please feel free to email me at

Can your local laptop or computer shop fix that?

by

As a computer repair shop we see a number of damaged computer-related electronics pass through our door daily, but we also see a number of strictly electronic items from time to time. For example we had a gentleman in our local town bring us a solar panel that had a damaged crystal oscillator, if you need an explanation this will help here: http://en.wikipedia.org/wiki/Crystal_oscillator, that we tested, changed, and repaired his unit.

To the point, we are not just an average break fix computer company. We are not just a degree holding computer repair facility. We are not just a reflow and reballing facility. We are an electronics company.

We fix TVs. We fix amplifiers. We fix stereos. We fix laptops. We fix desktops. We fix TCUs. We fix printers. We fix battery chargers. We fix about anything that can be soldered or tested with a scope, multimeter, or continuity tester.

We use only Hakko-branded equipment for our fine pitch soldering. We have all Fluke-branded electrical test equipment.

Below is an example of a system that was sent to a Florida-based repair facility off of eBay who could not fix the unit. Their solution was to replace the motherboard. For all their soldering knowledge, testing equipment, and time they only could suggest a motherboard replacement.

In the picture above the mosFET, http://en.wikipedia.org/wiki/Mosfet, was damaged due to a short overloading one of the gates. This simple solder work can only be performed by hand, with the right equipment, and with the correct knowledge.

After the pick and place parts repair was performed we had a fully working and functional machine for our client in less than 24 hours.

Now can your computer shop do this for you? If not, then we are willing to offer you a deal to try our service out in the state of Georgia.

This does not equal that.

I have found out over the past few weeks that local repair shops have been selling users one thing and delivering yet another.

I have seen this as a policy held by such shops as Leaping Liz’s, which seems to be a premium quality repair facility located in Dalton, GA, and The Computer Guys.

THIS PICTURE ABOVE DOES NOT MEAN YOU HAVE RECEIVED RAM. I am seeing too many users bringing me systems and calling me out to check systems that run slow after being worked on and upgraded that have never been upgraded. If you have a system that you have taken elsewhere and received a receipt saying you received RAM upgrades and were billed $50.00 for virtual memory you have paid for nothing.

Keep in mind virtual memory is not physical RAM or memory. If you are billed for a memory upgrade and get virtual memory that is, in my opinion, border line theft. To better explain it, virtual memory is not RAM but your operating system’s page file that copies running information from the physical memory to the hard drive and vice versa as programs are maximized and minimized and are clicked on or ran.

I have personally worked on a system last week that a user brought to me that was custom built by Morrison’s Computers that he had taken to Leaping Liz’s for a virus repair. The receipt stated he had been upgraded with 1.5GB of RAM. Upon opening his system up his desktop had the memory from Morrison’s original build in it, but his VIRTUAL MEMORY stated 1524MB of virtual memory. He had paid $50.00 for that upgrade.

As a consumer you have the right to a second opinion. If you have questions feel free to call me or email me. Both are free. I can be reached at 706-307-9689 or emailed here
