Question about IBM ThinkPad X41 Tablet PC

Open Question

Is it possible to unsolder a processor from a motherboard without sacraficing it?

I took apart my laptop only to find that the processor was soldered to the mainboard. I want to change out the processor because it burned up. I don't care if I ruin the processor, I only care about the motherboard. So, is it possible to replace it with another one of the same type? I have a camera, a desoldering pump, solder, and a soldering iron.

What do I use to resoder on motherboard of irulu ax101 tablet?


If you are asking how or what to use/do then maybe you shouldn't be doing it. Electronic circuits are not really forgiving when it comes to heat or shorts. Many electrical items can be ruined by too much heat or improper install. If you are trying to refloat a chip or processor you could ruin them or the circuit board.
If you must try you will need a quality soldering iron, solder (silver for electronics), flux, de solder wire, heat sinks, etc... who knows what else. Wouldn't advise doing it.

How do I get this apart so I can change/remove micro chip


Hi there,

I think you would need to check with the manufacturer, and the specifications of your tablet, to see if that is even possible. In many cases like in notebook computers the processor, is going to be soldered to the board. Assuming that it is a removable item, then you would need to find the compatible processors as well as a service or maintenance guide for the specific model of tablet for any assembly instructions.

I have an XO tablet for my kids but they've broken the charging port... is there anyway to replace the charging port myself


Hi Johhnie,


To repair a charging port you will need the following:

  • fine tip soldering iron (Weller 15 watt)
  • Dremel tool with cut off wheel
  • De-soldering Braid
  • Torx T5 screwdriver
  • small flat bladed screwdriver (optional)
  • Diagonal cutters
  • small hemostat or fine tweezers
  • Panavise, helping hands or similar bench top holding device.

Take off the back cover and remove the battery.
Next, whip out that Torx T5 and remove the screws holding the phone together. On this one, there were only four to remove.
With the screws out, gently pull the phone apart. The lower half of this Motorola clips together, so I gently worked around the edges with a small flat screwdriver until it came apart.
The SIM card board easily separates from the phone via the flat SMD connector. Just gently apply pressure near the connector and it comes right off.
Next, the flat ribbon cable needs to be detached in the same manner, and the main PC board removed from the phone. It should pull right out once the cable is disconnected.
As you disassemble the phone, put each of the pieces into a parts bin. Any sort of container will do, but I'd avoid a static generating plastic Tupperware container.
Carefully place the board in your clamp/Panavise/whatever - I had to line up the buttons with the slots in the vise, or I probably would have damaged them when I clamped the board
You'll need a new connector before you can fix anything.
In order to check the condition of the pins, clip the two tabs that hold the rear shielding on to the connector with a pair of diagonal cutters.
With the rear shield removed, we can access the rear pins - Unlike the front, everything looks pretty good. The advantage of surface mount parts is that they don't require much solder to hold together. Unfortunately, when you're replacing a surface mount part, a small amount of solder can keep you from removing the part without damaging the board.
To keep from burning this foam seal, peel it back and stick it off to the side.
Enter the rotary tool. Sliced the top off of the connector by cutting the sides lengthwise.
Next, cut across the center of the connector. The bent pins should be gently cut loose and the upper half of the plastic connector will probably fall apart. The shielding on the sides should be cut to allow each leg to be removed individually. (Be careful not to cut the PC board below!)
Working from one side to the other, heat up the solder pad on each pin. Then use some tweezers to grip each pin of the connector. (I used a small pair of alligator forceps) If the solder is hot enough, the surface mount pin should come loose with little to no force. It's vitally important to be as gentle as possible with each one. The solder pads on the PC board are very delicate, and easy to pull up if you're not careful. Unfortunately, overheating the pads can also cause them to pull up. So be quick about it!
With the delicate pins out of the way, I carefully cut apart the remaining plastic and removed it.
Finally, the remaining legs of the shielding were heated and removed from the board.
After the new port is aligned (double check the pins in the rear!) solder one of the shielding legs to the board. Double check the pin alignment again, and solder the other legs. Now the port should be solidly mounted.
Next, the pins on the new port need to be soldered. The super fine tip on my 15 watt Weller pencil made this easy. Alternatively, you can use a wider tip to solder things and go back over the pins with de-soldering braid to remove any solder bridges. If you forgot to remove the rear shield, you'll have one hell of a time soldering the pins. On this particular phone, the metal shielding behind the port made it impossible to access the pins without removing the rear shielding.

Regards


Martin

The charge light will no longer come on and my wife's Nextbook 10se will not charge, and the battery has gone dead. Where can we get another AC Charger for this Nextbook 10se?


Not sure if you have Princess Auto like here in Atlantic Canada but Walmart may carry something suitable. Staples as well; believe it or not! Ebay if you have PayPal or can wait a few weeks until it's all set up and you transfer funds from your bank account, takes about a week to get set up so you can but stuff on ebay or anywhere that accepts PayPal. I always look for local stuff on www.kijiji.com and YouTube offers a lot of videos on fixing most everything. Oops, just noticed the wiggle part in your description. Depending on where the wiggling was done the end of the charger cord can be cut apart and re soldered on but if the problem is inside the laptop then laptop will have to come apart and is either soldered directly on the motherboard or is a plug in on the end of a cable connected to the motherboard. YouTube search your device and problem for videos on how to fix this problem.

Tablet wont charge


I had this problem. I took apart the two sections of the charger plug and there were two silver wires in there. I thought they were leaning a bit together, so I just gently pulled them apart a little, put it all back together, and it works. Asus tablet, also dock, always charge successfully since. I hope yours does too if you try this.

Possibly a new battery, or charger. But it also could be that inside your device could have detached/unsoldered from the connection slot. If you know how to use soldering with electronics then that may be able to get it working if that is the case. I would not recommend this approach, the manufacturer or dealer may have to get it taken cafe of for you.

Hi i have a gateway laptop, im having a hard time fixing the speakers,it started wen i tried to use my speakers for my ipod.when i took the cord of my ipod out of my laptop,the laptops speakers arent...


You have possibly broken the switch, inside the units Phono Jack, this is a common thing, there is a little switch, in the Jack, that cuts OFF the Internal speakers, when used. Sometimes the ball on the end of the Plug can force the contacts too far apart and they don't make contact and cut off the internal speakers. This is a difficult fix, as the whole laptop must be disassembled, the part unsoldered, and another good part re-installed. As a cheap workarround, get an inexpensive USB soundcard, and some small external speakers. Otherwise it's off to the repair shop, or get yourself a service manual and do it yourself.

I have a Stylistic 5032D, running Windows XP Tablet, SP3. 2Gb RAM and 1.20GHz processor. I'd like to prolong its life - can I upgrade the processor or anything else to increase power? Thanks, Steve


Sorry no.

The CPU can't be upgraded as its a Pentium M 753 Ultra Low Voltage/ULV CPU.

Which is soldered directly to the motherboard.
And the max ram is 2gb which you have.
You can try a faster hard drive if currently you have a 5400rpm buy a 7200rpm drive, but this always brings more heat, and heat means lower battery life/time.

Good Luck.

Is a processor upgrade possible


no, it will not handle a pentium4, but you could get a much faster p3 for it. and the ram amount doesnt depend on the processor type, it depends on the motherboard and os. and it looks like 256 is the maximum ram for that model.
