Question about Toshiba Satellite LP154W01 Notebook
Replaced mother board due to ac adapter problem -
Now laptop has two major issues -
1) system will sometimes freeze up and have to be turned off -
and when turned on then -
(a)- sometimes video display does not come back up
(b) - to add to frustration - the power off button sometimes will not work - so unit has to be unplugged form power source
And - 2) will powered up the unit will suddenly turn itself off as if switched off
First clean the fans out - these get clogged pretty easily.
If it gets stuck where you cant turn it off - hold down the power button for 5 seconds.
Hopefully the system hasnt been overheating for so long it has damaged the CPU or motherboard.
If the fans are clean and it still does it, you may have a bad stick of ram or the mainboard you bought may have problems.
I would inform the company you got the mainboard installed that it is having problems right away in case you dont have much time left in warranty.

Tips for a great answer:
L300 series boot problems
L300 series laptops are very good normally but don't boot up if there
is a device in the USB slot or a CD/DVD in the drive.
If it still refuses to POST, remove the AC Adapter, remove the battery and remove the hard drive.
Power the unit up without the hard drive and it should complete POST and complain that there is no hard drive. If that doesn't work remove AC adapter, ensure battery is disconnected and remove hard drive and RAM. Try again. If it still doesn't work, you have a mother board fault and it needs a service centre. www.Toshiba.com will help you out.
If it does work at one of the options, when you have closed the laptop down, replace the RAM first and test, then the Hard Drive.
Hope this fixes your problem.
