I am wondering, can you plug a plain power strip (no surge protection) into a battery backup.  I just want to use it as an extension cord for my laptop.

Yes sure. No problem. As the battery backup (UPS) has its own surge protection for the output anyway. :)

Control button locked. when I turn ooff PC the sleep light will not turn off.

Typically, the computer is defaulted to stay turned off after an electrical outage. To start the computer from scratch again, hold the power button in for several seconds. If it powers off, wait a minute, then hold the button in again to start it. When the screen comes up that says it didn't shut down properly, choose Safe Mode without networking. It will look like it is hanging on several files, normal, let it go. The screen & icons will be large because it is in default VGA mode. Once it stops loading, go to the Start Button & choose Restart. Things will return to your chosen default settings and most things will work again providing you have an EMI/RFI Surge Protector power strip that everything was plugged into. I have had several fail after a power surge, they are supposed to. Some have insurance should you have electrical damage after a power surge that got beyond the strip. Ultimately, $15-$50 is cheaper than your PC &/or monitors damaged by not having one, they are designed to be the Sacrificial Lamb & be the cheap breaking point.

As an added note, people confuse Sleep Mode with Hibernate Mode. Sleep mode means anything you are working on gets suspended into your available memory while it goes into Power Saving mode. On a power loss, all will be lost, save regularly if you use this mode.

Hibernate uses a space on your hard drive to write the information. Power loss, nothing is lost and on waking up or powering back on, your data will still be where you left off, usually intact. To restore from either mode without electrical loss, hit the ESC key. Exceptions will occur if you use Hibernate mode but only have a power strip for your multiple plugs. A power surge can still damage your computer because it wasn't blocked by the EMI/RFI power strip.

How do you know which one you have ? If you only have an On/Off power switch, you have an unprotected power strip. If you have a button on the side of that switch, known as a Reset Switch, you have a protecting one. Even if the Reset Button doesn't restore the power strip, it gave it's blife to protect your computer equipment. Cheap insurance.

Good luck.

I have a computer with ups .in my area power flutucation is there .i connected all the devices to the ups .when power flutucation happens . it restarting my systems some times my modem got off and on for...

If it is only a very short fluctuation, your system should not shut down if the UPS is working properly. Some things to check...
1. Make sure you have your computer components plugged into the outlets marked "Battery Backup" not on the outlets marked "Surge Protection". (The words may be slightly different on different models) Only things plugged into the "Battery Backup" outlets will keep running when the power fluctuates. The other outlets do not get any battery backup.
2. If the unit has been drained by a lot of power drops recently, it may not have enough power stored up to keep your whole system running the next time the power drops, even briefly. Especially if it is an older unit, as the battery itself does wear out over time.
3. As for the "modem" clicking on and off... are you sure it's the modem clicking? Most UPS's make a noticeable sound when they kick into battery mode and back again. It can sound like a modem click. Just an idea.

It will not turn on please help me

Hello, I will try my best to help you, ok? I need to ask you a couple of questions so I can understand your situation more clearly ok?
1) Do you have your power cord plugged into a Power Strip or surge protector? If so, check and make sure that the switch is ON and/or the surge protector button has'nt been tripped.
2) Is there any sign of power to the Power Supply Box that your power cord is plugged into? (ie: led light, or sound of the fan inside of the Power Supply Box?)
3) Is the outlet that you are connected to live with power? (try plugging a lamp into the socket to make sure)

After you have ruled out the above possibilities, let me know, and we will go from there, ok?

Audio would crackel then screen would scramble, now unit just beeps when poweredup.

Sounds like you are the victim of a power surge. If you do not have a surge protected outlet strip, get one before you fix the pc (or buy a new one). If you do have a protected strip, you should know that they are only good for one hit. If ever, in the past life of a protected strip, it is tripped off, that is, you had to reset it, the strip is no longer protected. It will work for an extension cord (if it wasn't hit to bad) but it no longer protects your stuff (and any warranty for your stuff is now void).

As far as the pc goes, its probably toast. You could crack it open and look at the motherboard, inspecting it for burn marks but the damage may be hidden inside the power supply or somewhere like that. If your set on saving your pc, you may be able to pull the hard-drive, mount it to a different pc set up, and boot from it, providing the hard drive is not damaged (ask a tech friend to help you if you go this route). You may then be able to pull any files off of it you want to keep. Then throw away the old drive, it can't be trusted.

System will not boot when monitors turned on

This may not be a video problem at all (hardware or software).

You say your "monitors" and it makes me wonder just how much you have plugged in to each of your power strips. Or extension cor

If you have a UPS, then you can take full advantage of all of the plug ports. BUT if you are using POWER STRIPS (these do NOT protect against power surges), then you need to look at what you have plugged in. Some big devices (system unit or "CPU" as some people call it, printer-especially the AIOs, MONITOR) pull quite a bit of electricity, moreso than speakers, a modem, or other small devices). Sometimes you need to have the big components plugged in to their own power source in order to work. You can't have them plugged together because there's just not enough power to go around.

I would try to spread the power around the room a little more, and then see if the system boots. Don't go rewiring your house, if it does!!! LOL. It's the computer systems we are using these days. I've also had fax machines, routers, and a few other things not want to work because they weren't getting their share of the "juice".

Hp pavillion power problem

Perform the following steps, in order, until power is restored or it is determined that there is a hardware failure:
CAUTION: This product contains components that are easily damaged by ElectroStatic Discharge (ESD). To reduce the chance of ESD damage, work over a non-carpeted floor, use a static dissipative work surface (like a conductive foam pad), and wear an ESD wrist strap that is connected to a grounded surface, like the metal frame of a PC.
1. Disconnect all cables from the computer, including the power cord.
2. With the power cord disconnected , press the power button on the front of the computer for five seconds.
Plug in the power cord and test to see if the computer can turn on. If not, continue using these steps.
NOTE: If the power supply fan makes an inconsistent grinding sound or stops and starts erratically, replace the power supply.
3. With the power cord removed, flip the red voltage selector switch to the opposite position. Wait about five seconds, and then switch the red voltage selector switch back to its original location. Ensure that the voltage selector switch is on the correct setting, 115V for North America.
Performing this step ensures that the voltage switch is engaged and set correctly for your country/region.
4. Remove all extension cords, power strips, surge protectors and any converters that remove ground. Plug the power cable directly to the wall outlet and test to see if the computer can turn on.
