1. Meet cd-rom don't read dish or read disk capacity is bad, do not think that is a cd-rom is broken. A lot of times because baldheaded dirt and toshiba satellite l305-s5865 laptop cpu fan lead to the laser beam can't completely through. There is not much drive technology content, so the shell open, do a clean, most can be recycled. Be careful when operation, some baldheaded surface that layer coating is fragile, do clean time not too hard, anhydrous ethanol can't make too much.
2. You may have been computer "electricity". That's because chassis appearance insulating paint get off or socket no ground. Generally speaking, electrostatic not on the computer much effect. But if the electrostatic too much, or will be a small problem. For toshiba satellite l305d-s5874 laptop cpu fan example some very near solder joint moment caused by short circuit to restart, etc. So if have been "electricity" friend, you can consider to chassis ground, so that would be much better off.
3. If the mainboard integrated sound card is broken, can consider to buy a new sound card. If you switch to crown 8738, your motherboard is after 845 the model, there will be a problem, is to choose the shutdown, machine but to restart! In addition,toshiba satellite l305d-s5873 laptop cpu fan the use of innovation SB5.1 friend, this not drive in VISTA below. Have net friend made a out, but compatibility is a problem, often bluescreen. Innovation sound card only 7.1 above, in the VISTA can use, but no EXA effects.
In addition, some PinPaiJi sound card driver, even on the Internet to find the type of driver software, also can't act, or installed a small horn but it is not the sound, must want to to its official website up to use, estimation is made specific Settings, very depressed. Especially association!
4. Now the chassis, generally has toshiba satellite l305d-s5870 laptop cpu fan lead to the USB interface. Sometimes U disk and MP3 can normal use, can cameras and mobile hard disk is to use no, suggested that "could not identify USB device". This is very normal. Use camera, still had better advice inserted in the case of the port. And the mobile hard disk data usually have two joint, the proposed use of time all connected to ensure that the voltage stability, the best and followed by many. Because lead is through the line connection, sometimes a little contact bad will affect. If the system in use appear "USB device surge" such a hint, prove your motherboard have problem. No warranty period will go to change it.
