What voltage should the XM 1800, MSW, w/Xfer 1800 watt, Item #0245925 be putting out to ensure the batteries stay charged? The remote unit in the motor coach only displays 11.8 volts now when it usual

13.8 volts need to be applied to the batteries to charge them. The loose button you refer to is the circuit breaker for the inverter. when it trips it pops out and is not loose any more.

Avalanche 360RB, battery not charging. New battery installed same problem.

Assuming alternator is good:
Fusible link blown (usually located close to coach battery compartment),
switch not turned on for coach power (some models),
dirty cable ends,
charging relay/solenoid not energizing (check for corrosion and tightness before replacing solenoid),
broken/cut wire,
corroded connections in charging system,
wiring loose, deteriorated or open circuits.

My laptop acer aspireone mini laptop screen is blackout i can't get it started.

You might have a faulty Liquid Crystal Display [LCD] Panel Power Inverter. Or the LCD Panel itself might be faulty. Either can be replaced. The Inverter is relatively inexpensive, a replacement LCD Panel, a little more.

To test for a faulty screen, connect your notebook to an external Desktop Monitor, using a standard VGA Cable -> press and hold the Fn key bottom left of your keyboard -> press the Function key at the top of your keyboard with the image of the two monitors on it -> release both keys -> if the image sent to the external monitor is correct then the fault is likely to be in one of the components of the LCD Screen and you should take the notebook to a repair centre to test test and replace the faulty component(s).

If you cannot start the computer at all, but there is a constant or flashing Power Light Emitting Diode [LED] on at the front but no Hard Disk Drive [HDD] LED on, then either the battery is faulty, there is a loose Direct ()Electrical) Current [DC] Jack, the Graphical Processing Unit [GPU] chip is faulty or there is a damaged Motherboard Power Management Track.

To eliminate other possible causes of the symptoms you describe, remove the battery and connect the notebook directly to the mains electricity without a battery and then try to power the notebook up. If the notebook powers up and boots into its Operating System then the battery cells are probably depleted and cannot recharge, so the battery should be tested and, if found faulty, replaced.

If the battery is not the problem, check for a loose DC Jack. If the point where the the Power Cable connects to the notebook is loose and is either in intermittent contact or not at all in contact with its solder points on the motherboard, then power might not be reaching the motherboard. Loose DC Jacks can be re-soldered or replaced if damaged.

A loose DC Jack that is in intermittent contact with the motherboard, an electrical power surge or sudden power cut or disconnection of the power cable can damage the Power Management System of the motherboard. It is sometimes possible to repair Power Management problem afflicted notebook motherboards by replacing blown capacitors and/or bypassing burnt out or damaged circuit tracks by creating new ones. Extensive damage to a motherboard might make it uneconomical to repair. Replacement motherboards are available and could be installed but when combined with the cost of labor for the overall repair the price might be prohibitively high.

A faulty GPU can have new tracks made to it, or have a damaged chip (silicon chip) surface cleaned to restore lost graphics by two different processes, Ball Graphics Array (BGA) Reflowing or BGA Re-balling. Re-balling has the longer lasting and better success rate. When the surface of the GPU is too damaged it may not be possible to repair it.

All of these motherboard repairs require a laptop repair specialist to disassemble the notebook and test, replace or repair any faulty components. These repairs can be expensive and need to be weighed up against the current value of the notebook and the cost of a new replacement notebook.

The DC Jack is the socket into which the power cable plugs into your notebook. If it has come loose the the solder points connecting the jack to the motherboard have broken contact and that is why the notebook is not charging. A loose DC jack is not suitable for DIY repair unless you are experienced in internal notebook repairs and have all the right equipment.
The only way to get this fault repaired is for a professional notebook repair technician to completely disassemble the notebook and then either re-solder the original jack back into place or install and solder in a new replacement jack before reassembling the notebook. Because of the skill and time it takes to disassemble repair and reassemble a notebook, repairing a loose DC jack can be expensive, but if you look around you should be able to find an experienced notebook repair center that will do it for $50-$75 and give you a warranty as well.
A DC jack often become loose if it is allowed to directly bear the deadweight of the heavy AC/DC Adapter on the power cable or the cable catches on something wile connected to the notebook. the AC/DC Adapter should lie full weight on the floor during charging. If the cable is not long enough for the heavy AC/DC Adapter to reach the floor, then it should be lifted it up and placed on the desk or table beside the notebook. Any cable length problems should be solved by using a surge-protected power extension cable. Also, a notebook should never be carried around when its power cable is attached to it.

My toshiba satellite a205-5804 has a problem with the main board, when its plug in it freezes but when not , when is used whith the battery it works alright. a repair center told me is the main board, but...

Are you using the original charger or a universal replacement? As loose fitting power plug can cause this problem but so can a loose connection at the power jack (repairable) or a cracked trace on the main board from stress at the power jack (not usually repairable - ie needs a new board). JC

M55-S135 Randomly Powers Off Whenever Moved


The only problem i see here is the Battery contact with your laptop.
Its somewhere loosely connected. Just get it checked or you can test it yourself, hold the battery tight to your laptop and shake it and test it like it will shut down in any other case, if its not, then surely its a battery loose contact problem.

Hope this helps.

Presario 700 power problems

No the battery does not have to be in for the notebook to work. No the battery does not have to be charge for the notebook to work. It sounds like you have a AC jack issue. Check to see if the AC is loose. You need to get this repaired by a local notebook repair shop.

I hope this helps. Please rate.

Toshiba Satellite A105

The most common problem on these units is the ac connector solder joints break away from the motherboard. If you're sure the ac adapter is working, and the correct one, and it's not charging the battery (assuming the battery is good), it's most likely the problem. They don't have to appear loose to be loose.
Otherwise, it's motherboard time, or a loose screw, etc has caused a dead short on the board.
Good luck, if you have additional info, let me know.
