This is a standard fault with the m35. In fact, it's so common that there is really no need of any voltage measurements or looking for new power adapters and batteries...
Here's a simple way to see what the problem is: wiggle the power plug when it's plugged into the laptop. If it wiggles up and down then you'll need to open the laptop, and resolder the power jack. I've seen literally thousands of complaints about this issue, and I had to repair my m35 twice for this same problem...and then a year later it died (LEDs blink, fan spins and in a matter of seconds everything shuts down). The power jack, together with the Maxim power regulating chip make the m35 a touch challenge, and an easy fix at the same time. I wrote an illustrated PDF tutorial for these two problems and it takes about an hour to dissemble the laptop, repair the motherboard and put everything together. If you're interested, go ahead and read up on how to repair a dead Toshiba m35 laptop.

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 is turning on and off


Remove the AC adapter (Charger)

PROPER method is to disconnect the power cord of the AC adapter, from power; THEN unplug the AC adapter from the laptop.

Same thing in reverse to plug the AC adapter back in.
AC adapter is plugged into laptop, THEN AC adapter is plugged into power.

Unplugging the AC adapter from the laptop, while being plugged into power; can cause a Voltage Spike.

You may get away with it for years, and several laptops; and have no problems.

However it only takes ONCE, to fry out the SMD fuses, Multi-Layer Ceramic Capacitors, and Power MOSFET's, on the laptop motherboard's DC to DC circuit.

Jus sayin'.

Moving on........

AC adapter removed, remove the Battery.
Press the Power On button in, and hold in for a count of 10 seconds.
Let go.
Do this procedure 2 more times.

(Draining residual power)

Reinstall the Battery. Attach the AC adapter, plug AC adapter into power. Let the Battery charge 24 hours.
Then turn the laptop on, and tell me what happened.

Laptop wont recognize charger


Maybe you did damage a component due to overheating? What caused the Laptop to overheat? Does the battery work on another laptop?

My laptop won't boot. It's start and then it turn off by it self.


Here below are possible causes and troubleshooting steps of laptop that can't power on, hope it may help:
Possible causes:
1.AC adapter failure.
2.Power jack failure.
3.Motherboard failure.

Possible troubleshooting steps and repair solutions:
1.Test the laptop power adapter with a digital multimeter. It's possible that you have a failed AC adapter. If you don't have a multimeter, test your laptop with another known good AC adapter.

2.It's possible that power jack (socket where you plug the AC adapter) is broken. Remove the motherboard and take a closer look at the power jack. In some cases you can fix the jack by resoldering it on the motherboard. In other cases you have to replace the jack with a new one. Using a multimeter, test if the power goes to the motherboard through the jack.

3.If replacing the AC power adapter and jack on the motherboard doesn't help, most likely you have a bad motherboard. Replace the motherboard.

There's seems to be a short where the AC adapter goes into the Laptop. Loose parts in that area of the Laptop where the adapter goes in. It won't turn on. Maybe it's the battery.


Unfortunately, this is a frequent issue with laptops. Being moved around frequently can cause the AC Adapter to pull at the DC Jack on the laptop. If it is loose, it can mean there is a broken connection within the laptop. What you can try is powering the laptop on with it plugged in and the battery removed. If that doesn't work, I'd recommend going to your local Best Buy and picking up a universal AC Adapter. If that doesn't work, you can always return it, even if opened.

My Acer aspire 4935 is not recognizing the AC adapter. When ever I shutdown the system and connects the AC adapter, it works and the charging LED lights up. Once I press the power button to boot the...


Problem description:The battery charges only when the laptop turned off. The battery charge LED lights up as normal and the battery gets charged to 100% while the laptop is off.
When the laptop is turned on, the battery charge LED goes off even if the adapter is still plugged in.
Possible cause:1. AC power adapter failure.
2. Battery failure.
3. Broken/loose power jack.
4. Motherboard failure.
Possible troubleshooting steps and repair solution:1. This problem could be related to a faulty AC power adapter. It's possible that the AC adapter doesn't provide enough power when plugged into the laptop. To find out if this is your problem, you'll have to test the laptop with another working adapter.Replace the adapter if needed.

2. There is a slight chance that you have bad battery. Test the laptop with a know good battery and replace the faulty one if needed.

3. The battery charge problem could be related to the power jack. Maybe the jack is broken or not making good contact with the motherboard. It is necessary to remove the motherboard and take a closer look at the power jack. Resolder or replace the jack if needed.

4. If the power jack is in a good working shape and new power adapter with battery do not fix the problem, most likely you have a faulty motherboard. Replace the motherboard if needed.
