    Is there a way to change the settings on the computer so that it will run properly, without freezing when the adapter is plugged in??? Or is this a motherboard issue that would make it to expensive to repair.?

Identification

  • Computer shops say that up to 20 percent of Toshiba laptops brought in for repair have issues with overheating. Symptoms may be as simple as the keyboard and bottom of the laptop being very hot while the computer is working, or the fans running at maximum rotation while the system becomes very slow for several minutes at a time. More inconvenient issues are common, such as the system completely seizing up and having to be "killed" with the battery pulled out, or the computer may shut down all by itself with no warning. Sometimes the laptop works fine until the user starts any significant memory-demanding applications, like photo editing software, several Internet windows being open at the same time, or an Internet video stream.
Significance
  • A common problem with the Toshiba laptop is that dust becomes clogged between the cooling fan and the heatsink, a device which lowers the temperature by dissipating heat into the surrounding air. Now heat produced by the processor is trapped inside the laptop, and the fan cannot blow it out.

SOURCE: Battery won't charge

Hello,
This is true, you will not be able to charge the battery without the correct charger. For mostly all laptops, when the charger is not maintaining a charge, it is time for a new one. However, it does not have to be the manufacturer's adapter, but I recommend purchasing the battery made for the Compaq Presario M2000 Notebook.
NextTag.com has decent deals on these adapters. http://www.nextag.com/ac-adapter-compaq-presario-m2000/search-html

I hope this helps. Please let me know if you have any other questions.
Thank You, Raph30

SOURCE: Advent 7113 doesn't detect mains

It is highly posible that the jack in your laptop where you plug the main dapter is making a false contcat due to a problem in the welding of its connectors to the main board or to corrosion. Check if the rentral plug is not loose or if the plugs seems to be loose when you plug it.
If it is so, you need some expert technician to solve the problem by re weilding it or replacing it.

SOURCE: power plug socket on notebook has failed.

You will have to have a new d/c jack installed on the motherboard. Not a big job, but you might want to have a techie friend do it for you, as it will require some soldering.

Toshiba satellite L305-s5955 will not power up


If there is no power light and it can't charge your laptop, it is likely that the charger is dead. You need a new laptop charger. So try a new adapter to confirm the real issue.

There are two kinds of ac adapters for your toshiba l305-s5955

Toshiba Satellite L305 AC Adapter 75Watt 19V 3.95A

Toshiba Satellite L305 AC Adapter 90Watt 19V 4.74A

You should choose the right charger depending on your original adapter's specification. If the original one need 90w, you won't buy 75w that will bring damage to your laptop. If it needs 75w you can use 90w too.

COMPAQ V2000 BATTERY NOT CHARGING


Try to isolate the problem first. See whether it's a laptop issue or an adapter issue. If the adapter has a light, see if the light is coming on when you connect it. Also see if the laptop works if you remove the batteries and connect the adapter.
There could be several issues here:
1. Your adapter's light may be coming on, but it still might not be delivering power to the pin. If you have a multimeter, connect it to the terminals of the charger and see if you get a voltage reading; if not, there may be a problem with the cable running from the adapter to the laptop or the adapter itself may not be giving the right voltage.
2. The second possibility is that the adapter is OK, but the laptop's power connector is faulty. This will require a technician to remove the old connector and solder a new one into place.
3. If both the adapter and the connector are fine, then the problem is most likely with your charging circuit, which is inside the laptop. This circuit powers the laptop through the batteries, and will once again have to be inspected by a qualified technician.
Hope this helps

Possible cause: 1. Power adapter failure.
2. Motherboard failure.
Possible troubleshooting steps and repair solution: First of all, test the power adpater. Make sure the apdapter outputs correct voltage. It's possible that the outup voltage is not correct and the laptop shuts down to prevent the damge. Test your laptop with anohter known good power adapter.
If the problem still exists, even after replacing the adapter, most likley it's the motherboard failure. Replace the motherboard.

Toshiba a135-s4407 quit charging when pluged in, replaced battery and charger is putting out 17 volt 4.75amp


Whenyou connect the power adapter into the laptop, does the power LED light up? Ifnot then - The battery adapter or the adapter's power lead or the laptop's powersocket could be faulty. Check power adapter's DCplug that connects into the laptop power socket with a multi-meter, the voltageshould be slightly higher than the voltage that is printed on the label on thebottom of the adapter. If the voltage is zero or way below the voltage that isprinted on the label then the power adapter is faulty and needs to be replaced. If the adapter is OK thenconnect it to the laptop and power it up, then look at the power/batterycharging LED light and wriggle the power plug in the laptop's powersocket. If the power/battery LED light flashes and in a certain position thisLED light stays firm, then the power socket is either faulty or it has a drysolder joint where it is connected to the motherboard. This model Toshiba may have a power socket that plugs onto the motherboard.
This can be repaired but itrequires the laptop to be completely dismantled to get at this power socket andrepair. If you cannot DIY then I suggest you get a quote first.

I have a toshiba LT a205; the LED flashes 6x; what does that mean? the psu is rated at 19vdc, and puts out 18.5 vdc. The end of the power connector that goes to the mb only has 0.5 vdc on it, so I'm...


19volts is a nominal value. The AC Adapter will be fine from 18 volts up to 20volts because the power unit on the motherboard regulates the voltages very accurately.
You say you only have 0,5volts on the Mother Board power input. There's your fault. Between the Mother Board socket and the AC Adapter.
Replace the AC Adapter or Laptop Connection lead if you mean there is 0.5volts actually on the Mother Board but full oiutput from the Adapter.

My Toshiba A205 Satelite laptop runs on battery, battery gets charged using adopter when system if off. But the sytem will not run only with adopter or battery and adopter together. Reason ? or an easy...


First, you need to make sure your power adapter is providing enough power to both run the laptop & charge the battery. A very good way to do this is to compare your laptop voltage & ampere requirements (written on a sticker on the bottom of the laptop) with the voltage & ampere ratings of the power adapter. Voltages should be the same, or the power adapter's voltage about up to 0.5 volts more than the laptop's voltage rating. Amperage of the power adapter should be at least equal to or greater than the laptop's rating. It should never be less than the laptop's rating, or else the power adapter will be providing insufficient amperes to charge the battery. Of course, the power adapter's nominal amperage might be ok, but it degraded on usage. You can verify this by testing using a good or new power adapter.
If the battery did not charge using the new power adapter, take the battery off the laptop, & using a dry tooth brush, scrub in between the fins of the battery connector on the motherboard & on the battery it self, then put the battery back into the laptop & try again.
If this still did not resolve the problem, then the battery itself could be bad. Try it on another laptop, or try a good or new battery in your laptop.
If this did not work, there might be a possibility that the charging circuitry on the laptop's motherboard is defective & needs servicing. In order to do this, the laptop needs to be disassembled & the motherboard checked for defective/burned out components in the area near the DC jack. Any defective/burned out components found should be replaced, or you might need to replace the laptop's motherboard altogether.

Laptop won't power up without battery, needs 135W adapter


The ASUS power adapter is below spec and it may damage the adapter because the HP is drawing 45 W more power than it can deliver and will cause it to overheat.
The 17" HP requires 18.5 or 19 volts depending upon the model of the HP laptop (check the power requirements on the label on the bottom of the laptop). If the ASUS adapter doesn't deliver this voltage, it most likely won't power up the HP laptop.
Use the power supply/adapter from the other 15" HP. If this HP's adapter has a voltage output of 19 volts and the 17" laptop requires 18.5 volts, don't worry a voltage difference of 0.5 volts, the only problem is whether the power plug will fit into the power socket of the 17" HP laptop.

Toshiba m35-s456 no power


To test if the adapter is faulty check it with a multimeter.
Test the output voltage on the connector that plugs into the laptop. The voltage should be 19 volts (the voltage is printed on the label on the adapter) or slightly higher because the is no electrical load on the adapter.
If there is no voltage or if the voltage fluctuates when you flex the power connector, then the adapter is faulty.

If the adapter is OK, then plug it into the laptop and the jiggle the connector a observe the charging LED light and if it flickers the fault is the power connector on the laptop. This can be repaired, it needs to be resoldered or replaced.
