Will not boot up

SOURCE: Dell Inspiron B130 wont boot

First remove the battery from the PC! Leave it off for a short period of time! about 2min. This allows the computer to erase anything in temporary memory. Place the battery back onto th PC and try to boot it up. The other thing you can do is boot the pc up with just the power cord in place. See if it boots just from the power cord. Sometime the batteries from dell causes the whole entire PC to become unresponsive.

No, you'll have to buy a microphone and plug it into the microphone jack on the chassis.

If you buy a webcam, many have a built-in microphone in the webcam.

it could be that the ports where you plug in the charger is damaged. if you have an identical or a known good battery that is charged, try to install that and check if it works. you need a motherboard replacement if the system works with a charged battery.

USB wireless adaptor is the easiest solution. You can buy it at any computer shop.

SOURCE: Dell Inspiron 1300 - When I re-open the lid,Screen stays Black !

Your laptop either goes to hibernate or sleep mode when you close the lid. Then, when you open the lid up, the screen is still off because your pc already hanged/froze and could not wake up at all (usual problem in vista). Off course, hard shutdown would fix it. But actual fix is under power options on your control panel. Check your current scheme and edit it. There are options there that you can select to "do nothing when closing the lid"

Hope this helps
