Loose power port

The power port is very loose and if I giggle it I can get power but its a pain and its started to make a bad sizzle sound, so is there any other way to power up my Averatec 6200 series (AV6210x61-01)? I like this laptop and I could have the port fixed but is it worth it cuz it kinda old? What does something like that cost, if you don't mind my asking????

Any help would great, as long as you don't suggest I take it apart myself. hahahaha Thanks PennySue

Change the cord first if this does not solve the problem remove connector and bypass with a power cord.

PC Power Issue


If it only comes on when you move the cables but not if you don't then one of the cable connections (pins) are loose or internally broken. Unplug it and check each cable/pin for any loose connections, bent pins etc.

Acer battery no charge/plugged in "battery is criticically low"


This is a tricky issue, it's either a problem related to the battery or the adaptor.

Try removing the battery and just plug in the adaptor and see if the computer will boot. If it does then there's a problem with the battery and you just need to replace it, if it doesn't then there's a few other things it could be.

The two most likely options is that the adaptor is bad, or the AC port on the computer has become loose. Most of the computers I've repaired that had these symptoms was that the AC port was bad if the battery wasn't. The best way to test this is to plug in the adaptor and just see if it wiggles around a lot, if it's loose then it might not be connecting to the board correctly and will need to be soldered bad on. If it's not loose then the adaptor might be bad, you can test another adaptor on your laptop or that adaptor on someone else's but be carefull, I can't stress this enough, if you're going to switch adaptors you have to make sure that the voltage IS EXACTLY THE SAME and has the same amps, if the voltage is off you can damage the computer, if the amps is off you can damage the adaptor.

If by some fluke it doesn't seem to be the battery, and you tested the adaptor and the AC port doesn't feel loose, then the charging circuit in the laptop might be shot, in which case you'll need a new motherboard.

I think that covers everything, sorry for the wall of text

My Power Suplly makes a high pitch noise and the


The problem lies in the reduction of operational frequency. It is mainly caused during the loose of ferrite cores or failure of HV diodes across the primary coil.
1) Check the looseness of ferritte cores parts loose or fixed properly ?
2) If OK Just check the components parallel to the high voltage side of the big transformer.
3) Check low voltage schottky rectifier diodes. One must be shorted. Just remove and here the sound. If it disappears, it must be faulty. During this test, the output voltages may increase to three times also. So, to safeguard, disconnect the filter capacitors.
Solution :
1) If any of the core becomes loose, just join it properly with epoxy or glue.
2 & 3) If any device fault occurs, just replace it in case of schottky rectifier diodes better replace with higher capacity. Capacity with numbers are given below :
1N5822 => 3 A
F12C20=> 6A per channel total 12A
MBR 20150 => 10A per channel.
MBR 3035WT => 15A per channel

No air ... compressor seems to be working OK ... a loose air connection?


That would be agood place to start. Try starting the unit and pressing your finger over the head and see if the pressure guage builds air you will only be able to hold it for a few seconds but just to see if its compressing air. If so its fine and check the connection where it is adding air to..

Hard drive not found in bios.


Hi,

Thanks for using FixYa!

There are three possibilities why your HDD(hard drive) is not showing up. 1. Its already a bad drive (failing HDD mainboard). 2. Loose HDD cable inside your laptop. 3. Bad laptop sata port. Hopefully its just #2 but most of the time its #1. Bring your computer to a technician. They will be able to easily isolate the problem. I hope this helps.

Have a nice day

Intermittent power connection


I am guessing this is a laptop.

If so, the DC jack on the laptop is bad. The connection between the jack and the motherboard gets loose, or the center pin gets loose. The only fix for this is a jack replacement. It takes soldering skills. You can get it repaired for $100-200 bucks, depending on the shop.

If you have soldering and electronic skills you can do it yourself, but it is tricky if you have never done it.

The only other option is possibly the power cord is bad at the end, where there might be a bend. Sometimes both the power cord and Jack are bad.

Power problem


Check the port on the laptop where you plug in the adapter. Try to wiggle and see if you have a loose AC/DC input jack.
If yes, you need to have it repaired, unfortunately. If not, remove the battery then plug the adapter and see if you can see a light or if you can boot up the laptop.
You may try plugging it in on a different wall outlet.
Hope this helps.

Jack is loose where charger plugs in


This same thing is happening with my acer laptop. I sent it to the company about 3 months ago, and it happened again. I really need my laptop and cant take a month without it. I advise sending it in to be fixed to your laptop company.
Good luck (:
