For the last year Pomeroy Computing has been repairing the micro usb ports on tablets of all makes and models. A common and popular tablet I repair is the Asus Nexus 7, both the first and second generation (2012&2013). I think it’s worth it to revive your dead nexus 7 device
Most of the time the symptoms of a bad charge port are physical damage to the usb port (plugged in upside down) dropped, tripped over, or just yanked hard when it’s plugged in. They can also go bad with time and have a loose, wiggle effect having to hold the tip of the power cord in just the right angle to get it to charge.
I do the Nexus 7 usb port replacement for my standard $29 parts and labor rate with $10 return shipping. If you’d like to get a hold us for a repair inquiry you can do it here http://www.pcrepairhelp.net/contact/.
The Asus Zenbook UX51vz is the 15.4″ equivalent to the 13.3″ UX31 series ultrabooks. It uses acompletely different new dc jack I haven’t come across yet and is hard to find. At the time if this writing someone is selling these jacks for $44.99 on ebay. I typically pay $1.50-$3 for jacks so this is pretty high.
The jack itself uses a circular style barrel unlike the solid center pin most plugs traditionally use. In this case the plastic circular barrel had physically broken off leaving the inner wires exposed (See picture). This is a 7 pin socket that’s soldered directly to the motherboard. The notebook needs to be completely taken apart to the main board to correctly fix and replace the jack.
We perform the power jack replacement services for $99 parts and labor on the UX51 series and the tear down guide is featured below.

I do quite a few Asus Zenbook ultrabook laptops these days. Thin seems to be in and this rival to the apple air notebooks is a nice PC based alternative. With making a laptop so thin everything needs to get slimmed down including the power port. The small, thin dc jack on these is kind of frail and can get broken easily. It’s fine under normal conditions but almost no one keeps there ultrabook on a table with no mobile use.
This UX31a came in like many do with a physically broken and cracked plug. The center pin is also missing and was stuck inside the ac adapter. Sometimes you can push the broken pin back inside the charger tip with a bent paper clip but that’s no guarantee it will fix it.
The UX31A like the UX32A uses a 7 pin socket that’s soldered directly to the motherboard. You need to take the laptop completely apart to the main board to access it. This includes removing the battery and disconnecting the keyboard, fan and other connections and ribbon cables. We replace the broken power jacks on these models for $69 parts and labor.

This Alienware M15X gaming laptop came in with a loose power connection. The user reported positioning the power cord at just the right angle to get the notebook to charge. Eventually this stopped working completely. If this is happening to your laptop I would highly suggest you stop wiggling and get it fixed. Putting pressure on the port like that can further damage the motherboard beyond repair.
The M15X uses a nine pin plug that’s soldered directly to the motherboard. You need to take the laptop completely apart to the main board to access it. You can see in the pictures below the two voltage solder points have degraded and oxidized. This is a tell tale sign of what a bad power jack looks like. We perform the jack repair services for this model for our standard $69 parts and labor.

This Asus X53 series (very similar to the K53E and A53E) laptops came in with the typical loose dc connection. You can hold the tip of the power cord in just the right way to get it to power on. Be careful if this happening to you because to much force can easily damage the motherboard beyond repair. I talk to quite a few people that if they had fixed it right away when it went bad the notebook could have been saved. Due to the mid mount style dc jack to much force will snap the motherboard.
The X53 uses a five pin, 2.5mm dc jack that’s soldered directly to the main board. You need to disassemble the laptop all the way to the motherboard to access the broken port like the video guide shows below. We replace the bad connection with a brand new part for $69 parts and labor.
This Asus A54H laptop came in with a loose dc connection. I could hold the tip of the power cord in just the angle to get it to power on. This means the power connection is coming free from the motherboard. We can fix this issue with a dc jack replacement for $69 parts and labor.
The A54H uses a 5 pin, 2.5mm jack that is common to Asus laptop models including the K53, K54, X54, X44 and many others. This plug is soldered directly to the main board and requires the proper soldering iron and tools to successfully remove it safely. The notebook also needs to be completely taken apart to the motherboard to access it like the video below shows.
The A54H is different than the A54C because it has a dedicated ATI graphics card vs. integrated gpu.

This is what it should look like when the jack is removed.
This Asus UX21E laptop came in with an extremely loose power connection. Long gone was a time when you could wiggle the tip of the ac adapter in just the right angle to get it to power on. This laptop uses a rare power plug and costs $99 parts and labor vs. our standard $69 fix for broken jacks.
The UX21E notebook needs to be completely taken apart to the motherboard to access the soldered on port. It uses a 5 pin, very small jack. Know part # on this one was SD from Foxconn. The jack was so loose when I touched the soldering iron to the traces it just fell right off the motherboard with no de-soldering techniques.

Most Asus UX32a/vd laptops I work on come in with a physically broken power connector. In the pictures below you will see the missing center pin and the broken plastic part of the plug. The notebook needs to be completely taken apart to the main board to fix the power port.
The UX32A/VD uses a 7 pin plug that is soldered directly to the motherboard. Known dc jack part # S120508, S131127 (More will be updated when I come in to contact with them).

Like many Dell N5110 laptops, this one came in with a physically broken power plug. As you can see in the pictures the circular barrel that was once there is missing. Some users have reported the notebook can still work in this state if you hold the tip of the power cord in just the right angle to get it to work. This is not recommended and could cause further damage. Sometimes you will get an error “plugged in, not charging”.
This can be fixed by Pomeroy Computing for our flat $69 parts and labor rate repair. This includes the tear down and reassembly and a new dc plug soldered on. The N5110 uses a 9 pin port that is soldered to a separate I/O board or CRT board (Part # 10808-1, 48.4IF05.001, DQ15DN15). This separate board plugs directly into the motherboard. This is a nice design because if the dc jack gets so damaged the I/O board is damaged you won’t need to replace the main board.

The Samsung NP300 series laptops are pretty popular laptops these days and are common ones I work on. They do fall under the $69 parts and labor rate to replace and fix the bad power plug.
Most NP305V5A notebooks come into my shop with a physically broken connection. Some have the loose connection problem but being so new it’s usually because it was dropped or tripped over that broke the jack.
The 300V needs to be completely taken apart to the motherboard to access the socket. It can be replaced but requires soldering and the tricky part is always getting the old broken piece out safely and successfully. Its uses a 7 pin dc jack and has a small barrel for the center pin.
Below is a video of Pomeroy Computing tearing down the laptop to the motherboard to access the broken plug. There is also a video of the de-soldering of the old jack and a new one being installed.
