When I play my TV tuner on LIVE television, my Qosmio G25-AV513 will shut completely down after about 15 minutes. No lights will remain on and in about 3 minutes I will see lights and then can power it back up. I always hear a winding sound prior to its shut down. However, if I watch programs that I have recorded I can watch the whole program without any problems. I suspect I may need another fan. It makes a funny winding, stuttering, and hesitating sound more often now. I can configure regular PC's and would like to tackle replacing whatever I need to...

Your laptop may become overheated and that is why it shuts down, make sure the laptop is on a hard service so that the fan can get air. hot weather can cause problems as well.

Toshiba satellite L750-iq6 won't shut down or sleep?!?


That is a software issue with the OS. Was it always like this? If not, try a system restore to some time in the past when you know the unit was working fine.

Hi.

Take out the AC power jack and then remove the laptop battery. Plug AC power back in and see if the laptop will turn on. If it turns on let it boot the operating system and then shut down as normal, remove the power cord and reinsert the battery and again see if it will switch on. If it does then there has been a glitch with the battery. If it doesn't then there is a problem with the battery.

If the laptop won't switch on either with or without the battery then there is a possibility that the motherboard has developed a problem.


Good luck.

Hey! I recently bought SiPix A6. It works almost perfectly as it shuts down everytime when i have printed one page. Same thing on AC or batteries. If i try to remove batteries and reinsert, or remove AC...


I don't have a real solution but I do have that problem. first page prints fine. If I try to print again, the printer shuts off. I'm using a usb to serial adapter and I realized that if I unplug the usb plug then plug it back in, VIOLA it works agail BUT only for 1 more page! After each page, I have to unplug and replug the usb cable from the computer. I definitely think that this is a driver problem and not a power problem. On one laptop it work ok but starts making the above problems when changing paper settings.

I've read on the web about this problem. Does anyone have a solution?
