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.

Cameras can't upload if low on power. Charge batteries or plug in the ac adaptor to an outlet and try again.

Ac power doesnt work only in battery mode,adaptor output is ok


sounds like the power connector (where you plug into pc) is going bad. try twisting / wiggling connector. pause for a few seconds between twists to give circuitry chance to reconize power input. sometimes there is a green led that will light up when power adaptor is inserted. you can use that as a reference.

Ac adaptor for psp


this i'm afraid is a problem with the psp. to charge the psp off a computer usb mode doesn't need to be entered. so it will charge automatically and if not either the battery or psp charge port are stuffed. try a borrowed battery first then if that doesn't change it trade it in to eb games and get yourself a new one

very first thing u have do is if u have any other laptop try and connect the aac adaptor with that laptop and also try the battery if it is working with the other laptop that means the motherboard of the computer has gone bad u need to replace it and what also u can try is disconnect the ac adaptor and take out the battery from the laptop and the without ac adaptor and the battery press and hold down the power button for one minute and then connect the ac adaptor and put the battery back in and then try and turn on the computer and also what u can do is shut down the computer first and then just hit the power butoon once only to turn it on and then keep tapping f8 key on the keyboard and it will take u to windows advance options and select safe mode with networking and then try if it turns on to the windows screen or not......and if it doesnt turn ono then definately replace the motherboard...good luck....

R51 will only start on battery.


Well it sound pretty much like power is not reaching the laptop components so neither the computer turns nor charges the battery using the power adaptor. You mention that you used the power adaptor from other laptop (hopefully same model he he) so it is clear that the fault is not it.

It might be the power "inlet" , I mean the socket where the plug is inserted, it can always get broken.

Another theory is that it might be the power regulation circuit on the mainboard.

In both cases it requieres to send the laptop to be repaired.

A home made "solution" might be to dissassemble your laptop and test the power on the mainboard using a Voltmetter, this requieres some skils so if you decide to try it be cautionous.

Good luck!!

Toshiba Satellite A135 Battery Issues!!!


Here's what happened (The fix is at the end):

8 months after buying my Toshiba A135 the battery began charging only intermittently. It also would not run without the battery. I put up with it for a month then took it back to Best Buy to get it repaired under warranty. They kept it over 2 weeks then gave it back saying it was the battery, which they replaced. One week later I had the same problem again. Back to Best Buy. The guy at the counter said it was probably the battery, they had encountered a lot of that. I said no, explained it, and gave it over to be fixed. 2 weeks later I got it back. They had reset the BIOS, no hardware replacement. I got it home and it was not fixed. I took it back the next day. They kept it 2 more weeks. They replaced the motherboard. I took it home and...you guessed it the same problem on the day I got it home!!! I took it back with one week left on my warranty. I don't remember what they replaced the last time but I think it was the motherboard again. I got it home (2 weeks later) and THE SAME PROBLEM on the day I got it home. So, the lesson there is that Best Buy computer maintenance SUCKS!!

I called Toshiba to try to get them to fix it for free, and out of warranty. After several frustrating minutes of conversation with an accented person who just kept telling me that my warranty was up, I hung up and called back and got an English speaking person. SHE was very helpful, listened to my problem, agreed to give me a one-time fix ticket. They paid for the postage. When I got my computer back it was mostly fixed.

The problem was the module at the back of the computer where the power cord plugs in. It was defective. Some wire or solder had gotten loose. They replaced it and it worked fine after that, except that when it goes into sleep mode it will not wake up. I fixed that by turning off all the sleep mode options. BTW, a friend of mine with the same computer is now having the same problem.

Lap top problem


Hi

If the AC power light is blinking, try the following steps:

1 Cut off power to the computer by disconnecting the AC adaptor and removing the battery. The error condition will be interrupted, and the AC power light will stop flashing.

2 Put the battery back into the computer. Do not connect the AC adaptor. Try turning the computer on again. If the computer starts normally, the AC adaptor may be
defective and will need to be replaced. If the AC power light starts flashing, remove the battery, and continue with the steps below.

3 Connect the AC adaptor to the computer. Leave the battery out of the computer. Try turning the computer on again. If the computer starts normally, the battery may need charging, may be depleted, or may be defective. Turn the computer on, insert the battery, and then leave the computer running for several hours, which will deliver a slow, steady “trickle-charge” to the battery. Once the battery has been trickle-charged, it may begin working correctly again. If the trickle-charging does not prove effective, consider replacing the battery with a new one.

4 Connect the AC adaptor to a different power outlet, preferably in a different room. If the computer starts normally, there may be a problem with the AC outlet itself, or the voltage level available from it.

5 Verify that the AC adaptor is the correct unit for your computer model. The computer may not be able to start from an AC adaptor that is rated for less current (amperage) than the computer requires, even if the rated voltage is correct, and the plug fits correctly in the DC-IN socket. The labels on the bottom of the computer and the AC adaptor show the specifications for voltage ("V") and current ("A") for each device. The voltage level must match exactly. The amperage rating of the AC adaptor must be equal to or greater than that required by the computer
