Happy New Year, And Peace on Earth

I'd like to thank everyone for the End of the Year donations.  It really helped, now I am looking at getting some additional hardware to tinker with. As well as getting some newer i5, and i7 systems that have been failing.  For some that had thought I was making it rich with the blog (HA HA HA HA), but your levity is warming. 

Biggest donations : $19.57 

Smallest donation : $00.01
Most recent   $00.16   (not sure what that would be in EURO's but thanks)

Again, I wish all the readers a Happy New Year, and maybe every country can get along, after all no one is leaving the planet too soon, if they do, they usually have to come back.

Something Different - HTC Flyer/Evo View

Doing a number of things got me away from blogging and posting repairs So I'd like to take this opportunity to show something different.

I had gotten an HTC Flyer Tablet in a lot with items that I bought, and it was a nice tablet, but it would not charge! So I first rigged a microUSB port on the top of it to charge the unit.  But with that configuration the cover would not fit. So I searched for the exact replacement, and they are scarce. Very Scarce.  Plus you cannot find them on another tablet because 90% of them have the same problem.
Before and After microUSB mounts

Dead Tablet, No Power will not charge, will not turn on.

Cause -
The pin if broken in the microExt USB port.

Reason -
Failure Problem 1 -The amount of current that the tablet draws overheats the plastic inside the contact because of  how hot the contact gets. Then the internal pin connector sets deeper into the plastic. The microExt USB cable internal contacts pushes down on the connector contact. When the cable is removed, the contact on the connector remains down because the plastic was melted. In that position there is no (+) POS contact on the tablet and it cannot charge.

inverted micro USB replacement
Failure Problem 2 - The microExt  USB port (+) POS pin is pushed back. Instead of making contact with the cable when inserted, the pin is forced back into the connector. Essentially bending and folding into the connector. This sometimes happens with other pins such as the (-) NEG pin. If it happens with a data pin, no data or sync is possible, but the unit will charge.

Complaint -
Poor supply channels and distribution of replacement microExtUSB ports. Not sure if it is a proprietary part from HTC or there are just not enough in the market. 

Solution -
Final before closing up- cover with black electrical tape
Replace with an inverted microUSB port.  This port is readily available, and can be adapted to supply power to the tablet.

Conclusion -
This fixes the charge issue, but data transfer and sync can only be done via microSD card, or wireless, or via Bluetooth. 

The tablet was too good and smooth to just toss it. There are scarce boards that can found but expensive (because so rare) and generally only in China. 

Note:  Both Units Fail in the same manner - manufacturer defective parts - usually after warranty runs out. 

The HTC Flyer and the Evo View are identical except
The Evo is 32gb and Black in color and has a phone built in - 
Usually Sprint for the carrier and LOCKED 

The View is a White/Silver tablet only with either 32gb or 16 gb. All the covers and base is the same. 

Though many are missing USB port covers when purchased.

All Treats, No Tricks

Since a number of requests have been made, and considering others that may not be fortunate enough to obtain the videos.  I have dropped the price.  I cannot say how long they will be reduced, but you may wish to take this opportunity.

Several projects are in the works -
  Book based training
Write a technical manual that covers repairs as well a principles and typical problems. By model 

  Classroom based training.
2 -Facilities available- Chicago, IL area, and Charlotte, NC area

This avails the opportunity for internationals wanting to attend. Major airports direct from Europe and some Asian countries.

30 seat classroom, projector, whiteboard and course materials.  Those attending the course will be given the standard tool set that I use, and will be trained using them. This is to make sure everyone in on the same page and not to need a tool, and don't have it. Traveling attendees should 'check in' items in their luggage.  TSA is not friendly with some items. (oh well). Some chemicals cannot be taken onboard, checked or otherwise, but are available outside the US.

If you are wanting to attend November's class, please let me know now. Located in Charlotte. Because of major American holiday this month time and schedule is limited.
Charlotte,  Nov 18-22
Chicago (area) Dec 9-13

Mid Week Special 2 for 1

New videos coming out soon. DV4,5,6,7 and other headache model.
They will be on a limited time and number of downloads. Sorry but I have to work rather than monitor activity/

And because I will be rather busy with another project I may not be able to answer Technical Questions on laptops by email for a couple of weeks. 

The old videos may be removed or by request only. Since the Donation thing doesn't work, The subscription site is in the works.  352,000 hits and barely a donation. So...

End of 2012

Have a Happy New Year, Joyeaux Noel, Feliz Navidad, Froehlich Neue Jahre.

End of the year, and end of the video download.   I am trying to close out 2012. So if you would like the Videos download please see the previous post. AS they may not be available at this price in 2013.  Also expect additional videos to be coming soon. Well worth the price.

Also if you have gotten a solution - consider a donation.  That makes it inexpensive for all and worth posting the solutions.

Need Classes?

Classes forming for training in Laptop Repair.

The first class for training will be in 2013.  More details will be forthcoming as I am working out the locations for these classes.  Cities under consideration.

  • Dallas
  • Chicago (area)
  • Boston
  • Bay Area (CA)
  • Atlanta
  • Seattle

Classes will be 5 days covering laptop diagnosis, part identification, common problems and hand 'How To', Dead laptop, No Video, DC/USB Jack Replacement.  Since many tech become confused following circuits, this too will be covered.

Class size is limited to 10, due to space.

If you have questions related to this subject - Email Me

The DC and USB port replacement is being covered is that many techs will spend hours and hours replacing what could be done in little as 15 min.  This increases your profitability. Many tech  are still trying to replace Dell jacks with a soldering iron and solder wick, or desoldering iron alone.

Heat management - heating it up without burning the board or nearby plastic or LED's.
Identifying failure area whether it's PCI, GPU or memory related.
Clearing BIOS/CMOS passwords on some models.  Toshiba/Dell/HP

Two other possible international sites under consideration: London, and Belgrade. Depending on interest.

How to save your flooded laptop

This advice is for qualified technicians. 
If you are not qualified, do not continue because you may cause even more damage

How to properly clean laptop AFTER Flood or water damage. In most cases this will get your laptop back on, and if screen is damaged, you can use an external monitor to get your data off.  Backup immediately!!

First I want to mention that this may or may not help.  Depending on the amount of damage done electrically.

1: Do not attempt to turn on your laptop if it has gotten water damage!
2: Remove the battery immediately
3: Disassemble unit completely.
4: Disconnect CMOS battery or remove coin cell.
5: Remove Hard Drive.  (allow it to dry either by sunlight or air dry)
Do not reconnect HDD!, use USB adapter to connect it externally to known working unit.                                             Your data is more important than your laptop or screen!

In most cases your hard drive data should be safe if your unit was not on, or not in use during the event. They are sealed (except vent holes on older drives) SSD may have the best results.

What may be damaged beyond repair
a: LCD/LED screen - water gets between layers of glass and plastic - cost $65-100
b: Keyboard - water gets between membrane and contacts. - cost $12-24
c: DVD/CD - lens may have gotten dirty, but can be cleaned.

How to clean a motherboard after it has been under water.
After removing CMOS battery, place motherboard in pan. (turkey pans work well, or plastic bin)
Using distilled water. Aqua Fina works best, or the 5 gallon jugs from dispenser machines (cheapest method).
Not Dasani, Not sparkling water. 
No fancy brands with added flavors or sugars.

Bring water to boil in pot, or clean coffee pot (Walmart $18) Not a used coffee maker!!
Pour the boiling water over the motherboard, front and back.  Do this 3 times.
Blot on towel, Tap, turn over, Blot again.

Using compressed air, remove as much additional water as possible from the entire board. This includes under the legs of chips and between USB/HDMI connectors, SATA/IDE connectors and do this in a pattern from left to right or right to left. Just remove as much water as possible.

After that is done, set oven to 200 (not higher, higher temps will not help- only harm)
200 degrees should be sufficient to aid in drying, without damaging plastic covers, stickers and labels. Allow oven to preheat to temp. for about 20-30 min.  Check and if all is well and dry set aside a few minutes.

Remove, allow to cool.
Reassemble  - DO NOT CONNECT LCD/LED Screen!!!
test using External Monitor first.

Visually check LCD if it had gotten wet.


Water can become trapped between LCD layers
Water can be trapped inside the lid and short both board and screen!!
Models with CCL back lights use an inverter that takes the 12v through a small transformer and makes it as much as 300v to light the florescent backlight tube. LED screens do not use inverters.

Remember this is not a rush job and to follow steps, because it is a one way path you cannot backup or reverse.

Reassemble unit, and test.  Remember - do not connect LCD/Screen

Notice: I am not able to respond to the multitude of questions. This is simply an attempt to provide an answer for those that need it.

No guarantees, but it may help someone.
