Westinghouse Notebook power supply

I have a westinghouse notebook. I have had it for about 1 year. I keeps shutting off. Even if I have the electrical chord plugged in all the time. The longest it stays on is 15 minutes. The power light keeps flipping from grren to orange. Is my power supply dying and where would I get it serviced?

    Laptop runs fine for 12 - 15 minutes, then shuts off. I loaded Speedfan to monitor temperatures, thinking a thermal shutdown was causing the problem, but the Core and HD are running within parameters. Another possibility was an old graphics driver, but it is up to date. I took the back off and cleaned out the heat sink and fan area, but that didn't help. The only thing left seems to be the power supply, and I have no way of checking it without the help of a pro. Since it's a cheap laptop, I doubt I will invest more than about $50 in it. I'd rather find a good 2 year old IBM Thinkpad for $250. I'll let you know if I find the issue.

If it is under a year old it should be covered by warranty,so contact the seller or manufacturer,

It sounds very much like a power pack is on its way out, and they are a sealed unit ,

try it in another power point. if power point is working fine, but you still have the problem,

and its over the warranty period.

take it to your local computer store and have them test it for you ,they will also be able to order one in and sell you a new one ,if it is the problem.

good luck with that

Benefits of a UPS (Uninterrupted power supply


We all use many devices and equipments that run on electricity. For all these to function properly they need uniform power supply (constant flow of electricity). As the electric supply in many countries is not uniform there is a need for a device to correct it. There are many such devices available in the market today. For example UPS (Uninterrupted power supply), Voltage Stabilizer, Constant Voltage Transformer are such devices available today.<br /> <br /> <b><u>Why buy a UPS?</u></b><br />We can never guarantee that we will get constant power. The power supply always has fluctuations. Surges, Spikes, Brownouts, Blackouts and Noise can damage your electrical appliances especially your computer. To prevent this from happening you need a device that does power conditioning. Electricity has to be uninterrupted. If the voltage is higher than the specified level then it is 'Over Voltage'. If the voltage is lower than the specified level then it is 'Under Voltage'. Both Spike and Surge come under 'Over Voltage' category. But there is a small difference between spike and surge. If there is very high voltage for an instant but comes back to normal immediately then it is called 'Spike'. If there is very high voltage for a slightly longer period then it is called 'Surge'. If the voltage is dangerously reduced to very low within a short period of time then it is called 'Brownout'. When this happens, the computer can be seriously damaged. If the power supply is totally cut then it is called 'Blackout'. Noise can mix with electromagnetic or radio waves or any signals. This is called 'Line Noise'. This may also reduce the voltage level to very low within a short period of time.<br /> <br /> <b><u>How can the UPS provide power when the main electrical supply is cut?<br /></u></b>A UPS has an internal battery. With this battery charger, an Inverter is also present. The inverter converts the 'Direct current' supplied by the battery to 'Alternatinc current' as required by the computer. When there is electrical supply the charger in the UPS charges the internal battery. When there is a power cut, the battery kicks in to supply the DC which is converted to AC by the inverter and power is supplied to computer.<br /> <b></b> <br /> <b><u>What if the battery loses its power?</u></b><br />When there is power cut, the required power is taken from the battery. Therefore the battery keeps losing its capacity. If the power supply comes back before the battery is depleted then the battery charger will start recharging, but if the power supply doesn't come back then the battery keeps supplying until it totally drains out. When the battery drains below a certain level the UPS sounds an alarm for your to shut down your computer and turn off the UPS. Some UPS' even have a built in system that shuts your computer down for you after a certain amount of UPS uptime.<br /> <b></b> <br /> <b><u>How long can the UPS provide power when there is a blackout?</u></b><br />This all depends on the specifications of the UPS and the requirement of the computer. A 600vA UPS for example can supply power to a computer with a 550W power supply for about 10 minutes or more.<br /> <b></b> <br /> <b><u>Tips for buying an UPS</u></b><br />The backup time of your UPS is the most important you need to consider. Other than that, you should know how many KVA (Kilo Volt Ampere) your UPS has. A computer needs atleast 0.5 KVA (500VA) to function. If you are planning to connect more than one computer to a single UPS then you need to get one with a higher KVA.<br /> <b></b> <br /> <b><u>What type of battery does a UPS use?</u></b><br />UPS uses <b>SMF</b> batteries (Sealed Maintenance Free). These type of batteries can be used for 5 to 7 years continuously.

I have lost my instruction booklet and it has been almost 1.5 years since I have used the notebook. I cannot get it to turn off. It keeps saying Windows is Shuting Down; however, it is still on. Can...


Hi There,

Simply hold down the power button until the notebook shuts down. Then, restart the notebook and it may just boot up normally. If you're taken to a screen with options that include Startup Repair or Start Windows Normaly, try Normaly first. If it won't start, use Startup Repair the next time around.

When you leave a notebook off that long, Windows may have tried to install dozens of updates. You will need to patiently update Windows completely.

Acer laptop shut of during power outage .


From the Acer website:

Power Issues or Will not Boot
Solution
If the notebook does not power on:

Make sure the ac adapter is correctly plugged into the notebook and into the power cord.

If everything is plugged in correctly and it still will not power on, follow these steps to complete a ‘power reset' of the notebook.
  1. Unplug the ac adapter. Keep ac adapter unplugged.
  2. Remove the battery and keep the battery unplugged.
  3. Hold the power button down for 15-20 seconds. (Nothing will appear on the display and none of the lights will light up.)
  4. Release the power button and plug in the ac adapter ONLY. (Please note that a power indicator light should be lit on the ac adapter when it is plugged in).
  5. Normally power on the notebook.
  6. If the unit does not power on, remove the ac adapter and insert the battery into the system.
  7. Plug the ac adapter back into the system, the battery charging indicator light will light up.
    If the battery charging indicator light does not light up, the ac adapter may not be providing proper power to the unit, and may need to be replaced.
Also, depending on whether your power went down "clean" (quick and stayed off), or went down and quickly came back on and off many times. Or when it came back on "clean" (came back on quick and stayed on), or it came on then off many times, your power supply may have been damaged from the power surges Are you having any problems with any other appliances?

Hi civic-95-uk ,

Try performing power drain steps on thenotebook:

1) Remove the AC adapter and battery from the notebook.
2) Press the power button and hold it for a minute.
3) Reconnect the AC adapter, battery and try starting the computer.
Even if the issue is same then perform Hard drive self test from BIOS.

1. Turn on the notebook and press F10 immediately. Which will lead you to the BIOS setup screen.

2. Click on Diagnisis and choose hard drive self test. Perform both the short test and long test.

Westinghouse monitor model lcm 19w4. Screen keeps going black and you have to turn it off then back on to get screen back. Sometimes screen will work properly for hours, but sometimes keeps happening...


This looks like a power supply problem, due to internal
over heating. When it cools down, the power supply turns
back on, or an "over current/ thermal" protection circuit
trips. Shutting of the monitor off resets it, and then it trips
again.

I had an old Samsung 19" with an identical problem.
(see my other post)

Mine was caused by a leaky capacitor, but every
monitor is different. (I have considerable knowledge of
electronics, as well as a degree in engineering, so
I was able to fix it, but I would not recommend this to
a non-tech person.)

The 19w4 seems to be a fairly new wide format monitor,
probably still under warranty. I would take it back to the
store on a busy Saturday afternoon and scream blue
murder.

There is absolutely nothing you could have done to cause
this problem, nor is it normal wear and tare.

It is the result of sub-standard manufacture, and you have
every reason to take it back. Your case is stronger if
you don't try to open it.

Good luck, Martin.
