SOURCE: Dell latitude D600 battery charge light flashing

You have a ground fault issue in the DC JACK.

There are escentially 4 circuits in the jack and one is not making contact.

1: Negative Charge circuit (outter ring)
2: Negative Run circuit (outter ring)
3 Positive (Inner Ring)
4: Signal (center pin)

I believe the negative charge circuit (outter ring) is not making contact internally. Typically what happens on that model DC Jack is the tension contact metal becomes fatigued, and does not touch the outter ring.

This could come from Heat causing early fatigue of the metal.
Or normal wear, the metal has simply worn out from regular insert/removal.

Was the battery a Dell replacement? or was it a Chinese replacement battery?
Your charging circuit may have been damaged.

SOURCE: MA2 laptop, not charging battery, changed burnt 4407 chip, no LED now.

This unit had a RED CHARGE error. Replaced PQ38 solved the problem.

If you get an error on the charge circuit after replacing the PQ38 you should also replace PQ38 because it too may be blown. Make sure Pin 1 where the dots. Also check the MOSFET on the other side of the COIL too.

I agree. Batteries have a limited life. Also--once you have a new battery installed, be sure you let it discharge all the way (until the computer tells you it has to be charged--about 3% remaining) at least once a month. This will ensure you get the maximum life out of a battery.

Power button not working!!! This is different though....


This is a common problem that I run into. The battery will show charged when it really isn't. Take out the battery, plug the charger into the computer and try turning it on. If this works, you have a bad battery and it will need to be conditioned or replaced. If this doesn't work it could be a serious hardware issue.

My Electrolux Rapido wet&dry won't start. The battery is empty and the blue light flashes when I plug in the charger.


this sounds totally silly but is the power button on the vacuum actually off? Had the same problem, where the battery was completely empty i didn't know my son had switched the vacuum on put it on charge and the light was flashing. I took it off the charging stand pressed the power button then put it back....now charging perfectly. Anyone who doesnt have this appliance will think you sound stupid but its just a clicky button so visually the button looks the same on or off.

I have a fujitsu e8410 which will not start up properly, when i push the start button it shows power but then the fan comes on and the cap num and shift lock leds flash and nothing else. can you help?


When you plug in the power cord is there any lightswhatsoever on the laptop, where the plug goes in or on the AC Adapter of thepower cord?

When you press the power button do you hear fans running, hard drive spinning,lights on the computer, hear any beeps or lights constantly blinking, hear theDvD/CD drive click and the light on the drawer of the DvD/CD turn on for asecond or two? If so the laptop is trying to boot or may have booted, butthe screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with thelaptop and why it is not booting. Most times it's a motherboard issuewhen you hear beeps or blinking lights continuous.

Maybe your power cord is bad if you don't get anything to happen whatsoeverwhen you press the power button. And if that's true maybe you wasoperating off the battery the last time you had it on and since the power cordis bad, it was not charging the battery so the battery is drained and the powercord is bad.

Maybe you have a Static Charge Buildup. Remove the Power Cord, Remove theBattery, then Press and Hold the power button for 30seconds. After 30 seconds plug the power cord back in (leave the batteryout) and hit the power button to see if it boots. If it does, you can putthe battery back in and let it charge.

Bluetooth wont charge or power on. when charging the red light comes on. once disconnected from charger it wont come on


Indicator Lights:
1.Headset Status Headset Indicator Light
2.Powering on Steady blue, then intermittent flashes
(changes to standby mode)
3.Powering off Red appears and goes off
4.Standby Blue intermittent flashes
5.Charging battery Red solid light. Light indicator turns off when
battery is fully charged and headset is off.
6.Low battery Triple red flashes
7.Pairing mode Blue/red alternating flashes
8.Missed call Purple flashes. Press the call control button
to cancel flashing light.
9.Incoming call Triple blue flashes when ringing.
Power on and off:
1.Turn on the headset Press and hold the call control button until the
indicator glows blue. You will hear ascending
tones.
2.Turn off the headset Press and hold the call control button until the
indicator glows red. You will hear descending
tones. When power is off, indicator stays off.
If none of this is helpful then it may be that your battery is dead, if that is the case then you will need to replace the whole headset. The battery's are not replaceable.

Good luck from Headsets Direct!

E system 1212 Laptop won't switch on. Power


Laptops are so integrated that usually a system failure that involves power issues such as in your case where you cant get it turn on with anything on the screen mean the mainboard (motherboard) is damaged. This usually leads to buying a new laptop or paying for the board to be replaced which usually costs as much as the laptop.

I have a Dell Inspiron 1525 that won't start. The battery light would flash orange 4 times then blue once, and then start over with the same sequence. Pulled the power board and fixed the solder joints on...


This is directly from the User Manual:
If the computer is connected to an electrical outlet, the Battery light operates as follows:
• Solid green: The battery is charging.
• Flashing green: The battery is almost fully charged.
If the computer is running on a battery, the light operates as follows:
• Off: The battery is adequately charged (or the computer is turned off).
• Flashing orange: The battery charge is low.
• Solid orange: The battery charge is critically low.

Flashing lightning bolt on Compaq C300


This sounds like a battery problem. The best way to test this is to remove the battery and then power the laptop up with just the power cord plugged in but no battery. If the computer boots then the battery is bad you will need a replacement. Also try letting the battery charge for a day. Be sure that the charging light is coming on when you have it plugged in.
