My Dell Inspiron B130 will not turn on

The battery is critically low, indicating that it is not getting a charge from the AC adapter. If the system will not power on from the AC adapter, then the motherboard power connection is suspect.

Motherboards are about $100 on EBay

After traveling last week, and using my Dell Inspiron 1521 on a motel wifi, I now cannot get the RJ-45 port to light up. Can use the USB port and the wifi board to get on line but not the RJ45 cable. Help

You might have a faulty cable.
Try a different cable. The link LED light indicated that the cable is connected to the hub or router correctly and is making connection.

I hav a 95 berrta and im tying to put a head unit

Hello chrisuftring,

Here's a link to the wiring color code for the '95 Chevy Beretta.

You'll need to match the function of each wire from your head unit and the color code for that would be in your manual. Most aftermarket units are somewhat standard as far as power, accessory, ground, and speaker connections are concerned. But the wiring colors may be different for such leads as remote, power antenna, illumination, dimmer, and muting.

An Alpine head unit has the following wiring colors:
Blue - Power Antenna
Blue/White - Remote
Pink/Black - Audio Interrupt (muting)
Orange - Illumination
Red- Switched 12V+
Yellow - Constant 12V+
Black - Ground
Gray - RF Speaker (+)
Gray/Black - RF Speaker (-)
White - LF Speaker (+)
White/Black LF Speaker (-)
Violet - RR Speaker (+)
Violet/Black RR Speaker (-)
Green - LR Speaker (+)
Green/Black - LR Speaker (-)

With this head unit, you would wire Yellow to Orange, Red to Yellow, Black to Black, Orange to Gray, Blue to Pink, Gray to Light Green, Gray/Black to Dark Green, White to Tan, White/Black to Gray, Violet to Dark Blue, Violet/Black to Light Blue, Green to Brown, and Green/Black to Yellow.

Note that there are 2 "yellow" wires in your vehicle color code. You'll have to test them to determine which one is the accessory wire and which one goes to the left rear speaker. Using a 12V "test light" is the simplest. Connect one side of the light to ground. With the ignition ON probe the yellow wires. One of them should light the tester, the other one won't. Verify that the light goes out when the ignition is OFF and your have separated the redundant "yellows". The one that lit the tester is your 12V+ switched wire and the other one goes to the left rear speaker.

Hope this helps.

Dell inspiron 1521 won't turn on!

Try this: remove the battery and unplug the power, hold down the power button for 10 seconds, then plug the power back in, and try turn it on again. If this doesn't work, check the power plugin port, if anything in there is moving around, it might be broken and need to be repaired. Check for a local electronics or computer store for that. The only other problem I can think of is that the motherboard died, probably from over-heating. This usually requires a new laptop, or an equivalent price for a new motherboard. Good luck, I truly hope the first one works.
