Toshiba A75-S229 Hi , I have a toshibe A75-S229 Notebook, it is working fine, but lately I have a bit of a problem with it.... when it is on ...it will not charge the battery and shuts down within 20sec. , but when it is off it charges it.....what could be the problem...?? I thought it is a matter of cooling , but it is not....please help me with this problem..

Remove both sticks of RAM. Insert the "new" RAM where the "old" RAM was, and see if your computer reports "zero" RAM or 1GB of RAM. If the latter, put the "old" RAM into the "second" slot, and see if the detected RAM is the sum of the two sticks.

Hi there,

The way to find out if it's just the screen is to connect the laptop to an external monitor. Pay attention to the F keys when you connect the laptop. On most Toshibas, you'll see a small depiction on the F5 key of a laptop next to a monitor. You either have to press that key alone, or hold down the fn key and then press the F5 key and let go to transfer the signal to the external monitor.

If the external monitor shows up good and you can perform all other functions on your laptop while viewing the monitor, you need only replace the laptop LCD. If it does not display correctly, then you're into the next round of troubleshooting.

Hope it works as above.

Good Luck

Hi,
No the screen is fine the back light is not working you have replace the back light of the screen to resolve the issue.But before that please try the FN+F6 or F7 keys to control the brightness.

there is a pannel on the bottem side about the size of a credit card with one screw in it, that will give you access to the memory ports, then just install the new memmory.

Do not have to change anything
