Having problems with your Dell Inspiron 9400 Notebook ?

My Inspiron 9400 started going off and all the lights would go off with the ac power cordYou could wiggle the cord which connects in the back a little and sometimes the green light would come on. The AC adapter is getting hot too. Are the adapters going out or is it the connection on the back of the laptop. How can I fix the back conncection?.


Answers :

You could have a power adapter problem, the adapter usually quite warm to touch but not very hot.
\015\012
\015\012Check your mains adapter plug that connects into the laptop power socket with a multi-meter, the voltage should be slightly higher than the voltage that is printed on the label on the bottom of the adapter. If the voltage is zero or way below the voltage that is printed on the label then the power adapter is faulty and needs to be replaced.
\015\012
\015\012If the adapter is OK then connect it to the laptop and power it up, then look at the power/battery charging LED light and wriggle the power plug in the laptop's power socket. If the power/battery LED light flashes and in a certain position this LED light stays firm, then the power socket is either faulty or it has a dry solder joint where it is connected to the motherboard.
\015\012This can be repaired but it requires the laptop to be completely dismantled to get at this power socket and repair. I suggest you get a quote first.

My HP Pavilion dv9700 was over heating and would shut off. Then it wasn't over heating and would shut off. Now it won't turn on at all. The power cord is working and the lights go on for a second while I am pushing the button to turn it on, but the computer won't turn on. HP told me the problem was the motherboard. Do you think that's really the problem or could it be something else?

CPU overheating I was wondering if anyone knew about any cpu overheating problems with the gateway MT3422. I have read several articles on this issue, and wonder if this may be my problem. I noticed that the laptop does get really hot, even with a cooling unit underneath it. The computer is now not wanting to turn on after restarting due to recent updates. I get a power light on after pushing the button a few times, no other lights are on, the CPU fans does turn on and the cd rom does spin. F 12
