Question about MSI Computers & Internet

Open Question

I took my Msi ge 70 1757 apart to replace the charger pin. Unfortunately the pin failed several times. Long story short the last time I took it apart it had no power when I turned on the switch.

I disassembled all the cards. laptop about 5 years ram is seated OK I replaced the switch, still no power only the battery light on.

Check your overload breaker. If it is tripped or bad you will not charge or invert power.

SOURCE: 99 Jeep Cherokee Sport, 4.0L -won't start

you need to have it connected to an OBD2 machine and watch if you are missing the cam sensor showing RPMs
or if your missing crank sensors RPMs,
it could be a wiring problem or computer if your seeing the RPMs from both sensors,and the last thing i would check is hooking up a fuel gauge to the reed valve and watch what fuel pressure you have while cranking,if the cam sensor is the culprit it will turn the fuel off after the cranking.

disconnect one terminal of the battery then measure charging voltage betwen +ve and -ve it should be 13.8vdc for one 12v battery if charging voltage is not present then battery is ok then connect ammeter to measure the current in Ampere .take care it should be in series if current if no current then battery must ok opern the ups there is a charger transformer measure i/p voltage to transformer if not present then check i/p path if present then check diodes at o/p of charger if faulty replace it also check capacitor and regulator ic if faulty replace it your problem must be solved

SOURCE: Hp laptop... black screen... caps lock flashes 5

When the Caps Lock flashes, it is then being used in a diagnostic mode. 5 times flashing means a problem with the System Board.

Motherboard.

I don't doubt it.

Two common problems, all based on one issue.
Overheating.

1) Problem One;

Primer;
The Processor, and the GPU are the two hardware components that produce the most heat.

[ GPU = Graphics Processing Unit. Slang? Graphics chipset,

Chip and Chipset are slang terms for I.C.
Integrated Circuit,

http://en.wikipedia.org/wiki/Integrated_circuit

GPU,

http://en.wikipedia.org/wiki/GPU ]

It could be something as simple as foam has melted, and melted down onto the motherboard, near the Processor socket. Removal puts the laptop back into service again.

It could be much more complicated, and follow an issue that has beleaguered the HP Pavilion dv2000 series, dv6000 series, and dv9000 series.

The cooling system for the GPU is inefficient. Allows the GPU to overheat.
Constant overheating partially melts the solder connections of the GPU to the motherboard.

The graphics chipset (GPU) is mounted to the motherboard with a BGA surface mount.
Ball Grid Array,

http://en.wikipedia.org/wiki/Ball_grid_array

To explain the BGA surface mount;
Compare to an older Intel Pentium 4 processor, and it's Socket 478 processor socket,

http://en.wikipedia.org/wiki/Socket_478

The processor has contact pins on the bottom. (478 of 'em) These line up with matching socket holes in the Socket 478 processor socket. (478)

With a BGA surface mount there are no contact pins, nor socket holes.
Solder Balls take the place of the contact pins, and Copper Pads take the place of the socket holes.

The graphics chipset's Solder Balls, are lined up with the matching Copper Pads on the motherboard.
Heat is then applied at a specific temperature, and length of time.

This procedure melts the Solder Balls, and solders the graphics chipset to the Copper Pads.
(Motherboard)

With constant overheating the solder connections that were created, start to melt. This creates a poor connection.

The professional method to repair this problem, is to use a BGA Rework Machine, to Properly re-solder the connections.

Due to the location of repair shops that have a BGA Rework Machine, and the C-O-S-T, many are attempting to perform the procedure with a non-professional method.

A thin metal shield is cutout in the middle, for the graphics chipset. This shield is set over the graphics chipset, and lays on the motherboard. Heat is then kept just to the graphics chipset, and the other components on the motherboard are protected.

Heat is applied with a propane torch, or a hot air gun, (Not hair dryer), in a circular (Spiral), pattern to the graphics chipset. With a more proper method used, the tip of a thermometer that can read this heat range, is laid on the chipset, and is used to keep the chipset at a specific temperature.

(Too much heat will burn up the chipset. Too little will not properly remelt the solder connections. A Cold Solder joint, or joints, will result)

The heat from the heating instrument, (Propane Torch/Hot Air Gun), is rotated around in a spiral pattern on the chipset. Constant moving around to distribute the heat evenly.
(You do not want a 'hot spot')

When the specific heat range is met, the heating instrument is slowly moved away from the chipset.

Move up an inch or so, keep spiraling. Then move up another inch or so, and keep spiraling the heat source. Slowly move up in increments while spiraling. S-L-O-W-L-Y back away. Method is used so that the chipset slowly cools down. Otherwise a cold solder joint, or joints, could result.
(Right back to where you started)

This link is to a video that shows one style of the procedure. It is not an advertisement for the video, just linked for the procedure information,

Temp, fuel, speed, RPM, Mileage guages are not working, Check engine light,abslight and alarm set lights are on. What is the problem and solution?


I had the exact same problem. The next thing you'll experience is immediate engine stall/quit right after startup.
Found the solution on another site: the fix is an easy do-it-yourself project: the solder used to connect the multi-function wiring plugs to the instrument panel has become brittle. (widely known to Chrysler and many repair shops. Their suggested fix is to replace the entire instrument cluster for 2-300 dollars (parts only; add several hours for labor).
For an hour of your time and a small battery-powered soldering pencil, you can simply re-solder each of the pin connections to the circuit board. Use new flux-core solder; it will make a lasting repair.
There's a You-Tube video out there showing the entire dash area disassembly and cluster removal. I did it twice; the first time, I only re-soldered one of the plug sockets. Disassembly took an hour- reassembly took 15 minutes. I should've re-soldered both. Second time, disassembly and reassembly each took 15 minutes. The actual soldering took about five minutes.
While apart, you can replace any burned-out dashboard illumination lightbulbs, too.

If the laptop battery is more than 3 - 4 years old then the battery could be worn out. Rechargeable batteries have a finite number of charge and discharge cycles and will lose their charge capacity over time, i.e. won't charge to 100% and gradually the charge reduces until the battery won't charge up at all. OR The battery shows a 100% charge but when the adapter is disconnected the battery drops off to zero capacity in a very short time. If the battery drops to an unacceptable charge level then the battery needs to be replaced. Rechargeable batteries will fail if stored in a discharged state for long periods.

Three long beeps may signify a keyboard error, and 3 short may refer to memory error. These are best guesses, because MSI uses several BIOS manufactures. Test your RAM one chip at a time to help isolate bad dimm.

It has not got a complicated power supply. I don't understand why it would take 5 weeks to repair. Parts are available from Mouser/Farnell/RS etc.
Repairs would not be expensive. Replacement is another story but a competent engineer will repair the faulty unit.

My katana lx wont charge. It took awhile to connect and charge last time, but now nothing.


I am going to assume that when you say it took you a while to get it to charge last time, you had to wiggle the charger around and then get it in just the right spot to get the phone to charge, if this is the case there are only 2 solutions try another charger if that works you just have a bad charger, if that fails than something in the port on the phone is bent loose or broken and it will need to be repaired in your providers repair center, if u have insurance u might need to file a claim.

You have a stuck pad on the control board. Push every button several times to try and clear it. If that does not clear the stuck pad you will have to replace the electronic control.

Dead unit


My Quest2 has a short in it that drains the battery even when it is turned off. But the battery lasts normal 15 to 20 hours when fully charged and unit is on. Whenever the battery is completely dead, I have to place it on the charger for a hour or two before the unit will even start even though it is plugged plugged in. The battery can be replaced by the staff at batteries plus for under $60.00
