Chosen Solution

Hello, I have a Toshiba Satellite L300 which is 3 years old by now. 2 months ago it started to freeze or restart after some minutes connected to AC power, in battery it works nice, and it’s able to recharge the battery when turned off. I took a long to identify that it was the AC power because it used to work for some minutes before shuts down. As the days go by the problem got worst and now it hangs at the same moment when I connect the energy. I’ve read a lot about this problem and tried different solutions. Tried another cable, cleaned the fan, monitored processor temperature, I’ve disabled one of the processors using BIOS, changed processors frequency to “always low” in BIOS, changed memory cards, removed the battery, pressed the on/off button for 30 seconds, removed hard disk and tried to use a live CD, I also have tried to configure laptop-tools (a linux tool to manage energy) but I don’t know if I did it right, I was trying to set (in linux) the notebook to behave the same way in terms of energy with battery and AC power. My readings indicates that’s a common TOSHIBA problem and it’s hardware. I send to 3 technicals assistance and they were unable to solve the problem. One of them told he changed the “BGA” chip (i don’t know what it is), he said it worked for some time but later the problem appeared again (I don’t believe it). Some people say they can use it in Windows safe mode, but I don’t have Windows installed. I’m running Ubuntu Linux and I definitely think it’s not an OS problem since I tested with other OSs including Windows, actually I tried to install Windows but I was unable to finish since the battery autonomy is not enough (<1h) and in AC power it freezes anyway. If anyone knows how to do it, tell me please. My battery now just hold 30 minutes and my notebook is almost useless by now. Best regards, Felipe Costa

Solutions :- THIS IS BECAUSE OF MOTHERBOARD PROBLEM, U NEED TO REPLACE CAPACITOR PACK WHICH IS AVILABLE BOTTOM OF MBD. thanks………..

100% ok…………go to safe mode in windows ,, go to ,cantrol panel … go to device manger and disable both processor 100% pc will ok

OMMMGGG I THINK I HAVE THE SOLUTION TO THIS!!!!!! WELL I HAVE HAD A PROBLEM WITH MY MSI GAMING COMPUTER FOR SOOO LONG!!! WHAT I DID WAS GO TO -CONTROL PANEL -THE DEVICE MANAGER -THEN GO TO BATTERY -THEN DISABLE Microsoft AC Adapter and Microsoft ACPI-Compliant Control Method Battery after you do this you will see that the battery notification thing on the bottom right of the screen goes away… but it will still run and still charge your battery if you plug in your charger. HOPE THIS HELPS!

Hi Felipe, As an owner of this laptop, and as someone who does computer work for spare $$- it sounds as though the actual internal connection may have broken (where the power pin is inserted)…It’s possible that the solder has broken/cracked & this may be causing a short. I’m only guessing (obviously)- but based on what you’ve said here, there’s not much else…You did say you “replaced the cable”- but did you actually replace the entire power unit, or just the one cord? Places like the large electronics shops (Best Buy, etc) have generic chargers that run around $80US. Ask to verify it will power your unit- if it doesn’t work- don’t buy it. Lastly, I bought a generic, new, replacement battery on ebay for $38. Cheers! Tracy

please you do not need to change the mother board, all you need to do is go to control panel then power option then put it to high power or maximum then see how it behaves,

I had that problem (restarted when plugged in) I disabled both processors and for a time it was good, but after sometime the problem came back again, so I took the laptop to a repair shop told them what was the problem and that they needed to replace the NEC/TOKIN OE128 Proadlizer Capacitor, they did that, I paid 86 euros and the problem is gone. All is fine now.

My HP Probook hang, I reinstalled Windows many time but no success, if I remove AC Power it does not hang. I think bad AC Power mostly causes this hang. I will try new AC Adapter.

go to safe mode in windows ,, go to ,cantrol panel … go to device manger and disable both processor 100% pc will ok saved a Toshiba Satellite A305 with Windows 7 64-bit from being thrown in the garbage. Thanks Amjad.

Not too sure, but I’m thinking this refers to reducing the max performance the CPU will operate at? I’ve read this in other places, as well. All I can think is that, at the 100% setting, the motherboard in question is overheating- or that the CPU is unable to sustain a 100% output (defective/overheating perhaps due to improper heatsink placement?). So, by going into the performance/power settings, you’re able to reduce the high-end of the CPU from 100% to whatever you’d like (say, 75%). It may slow the PC a bit, but it’s better slower than “dead”? Read here. FYI

Your Laptop will definitely be OK . Just try this - In the search box write services and click. Go to power options in rigth hand side of the services box. In General category change start up type from AUTOMATIC to DISABLED. Click Apply - Ok. Restart your computer. Your problem is solved. Dr Rajneesh

you need new original charger
