Question about HP R1500 XR (204404B31) UPS System

Open Question

UPS suddenly inoperable

I purchased a rebuilt XR1500R UPS to use in my home theater rack.

It was too loud so I replaced the fans with quieter ones and ran them at half speed, and added 2 additonal fans inside and a third one mounted to the rear, to improve airflow while still keeping the sound down. I'm running the two main fans at 6 volts and the other 3 at the full 12 volts.

After setting this up, I left the machine to run on AC with no load, and when I checked on it about 12 hours later, the keypad had locked up, every indicator light was on, the internal fans were shut off and there was no power available at the outlets.

The only way to get the lights to turn off is to disconnect both AC and the battery, but plugging in the AC or the battery and pushing the on switch causes the lockup again.

At this point, the device is unusable.

Any suggestions for repair would be accepted with much thanks.

SOURCE: HP Pavillion dv9000 - won't power up

I had the exact same problem so I called HP support.The instructions were- remove power cord from lap top if power cord is connected, then remove battery, connect power cord to lap top then turn on lap top by holding power button down for 30 seconds. It booted up, no problem. The proceedure is to remove static electricity.

SOURCE: won't turn on

*Unplug the AC cord
*Remove the battery
*Locate the memory cover on the underside of the notebook
*Unscrew the one or two screws securing the memory cover, and lift up to remove the cover
*Gently slide (away from one another) the metal retaining clips that hold down the module.
*The module should pop up
*Remove the module
*Reinstall the module (removing and reinstalling the module is apparently enough to rectify the contacts)
*Replace the module cover and the battery
*Attach the power cord
*Try to power up

For all those with the ZV series power jack problem, I have replaced a few of these jacks and it is not an easy job unless you are an engineer.

The entire laptop needs to be disassembled, all the panels need to be removed, including the keyboard and you almost have to remove the motheboard.

Even when you eventually gain access to the offending part, you will need to be competent in using a soldering iron to remove the jack without damaging the printed board, then clear the holes so the new jack can be fitted.

While you are doing all this, you need to remember that the circuitry is static sensitive. This means that you can kill your motherboard just by touching it.

When you have finally finished the job, unless you have been pretty smart, you'll end up with a box full of different size screws and you won't know what goes where!

With the ZVs I have repaired, I usually supply a short jumper lead that plugs into the power jack on the back of the laptop. This is two or three inches long with a cable power socket on one end and a power plug on the other. This means that the user can leave the power plug plugged into the laptop all the time and just disconnect and reconnect the power unit from the other end of the patch lead instead of wearing out the laptop's power jack.

SOURCE: No Power - Power Indicator 3 Seconds

This line of hp notebooks is the most notorious for power jack issues. There a re a few different symtpoms but 95% of all problems can be fixed with a power jack resoldering or replacement. It very rarely damages anything else on the motherboardis and seldom has anything to do with the power adapter/supply itself. There are a few options:

1) take to computer repair shop and get new power adapter. (As this requires a complete tear down of the notebook, it can be a bit expensive in terms of labor. The part is less than $10 on ebay and is readily available. You can download the service manual and break down the notebook yourself and take just the mb and new adapter to the shop and save some money. I don't recommend attempting to soldering on the MB yourself

2) If you don't need portability as much as just being able to use the laptop at home, then purchase an xb2000 expansion base from craigslist and power thru the docking port on the side. Be sure and confirm that the adapter is included with the purchase as some owners may have discarded it since their particular model didn't need it.

3) If you can manage to get an XC1000 cable for a reasonable price off ebay or craigslist, this is a portable option. However, as they stopped making these All-In-One media cables a while back, those who have them know their value and command a pretty hefty price. I personally would rather pay a computer repair shop a $150 before I pay some person who capitalizes on my misfortune.

4) I am in the process of confirming this least expensive solution but I don't see why it wouldn't work.
-- adapter from the xb2000 expansion base (you can pick these up cheap or free)
-- xc2000 all-in-one media cable ($35 - $50)
-- 120w power adapter for Presario R4000,R4100, R4200, and Pavilion ZV6000 (oval shaped multi-pin connection required.) Note: The original lower wattage adapter will not work. ($25 - $30)
Although this solution may cost a little bit depending on how creative you are, you can sell your old power adapter to offset the cost of the new adapter AND you can sell all 3 for what you paid when the laptop dies completely.

5) the paper clip trick has been known to solve a few problems where the connection in the socket is the problem

Ultimately, you can purchase a MB and replace it your self, the MBs run around $150 and you can use the service manual to break down the notebook. However, this is only a recommended solution if you have video problems since breaking down the laptop is just time consuming and the soldering of the power adapter is cheap

My avs 2000 makes a load hum


One of the 'cons' of the AVS 2000 is that it makes an audible 'hum' when switched on that can be heard during quieter moments. This shouldn't be overly loud though - If it is, I'd take the unit back for replacement / repair.

You could have done a very slow damage to the Yamaha if your UPS was not a pure sine wave type ( on line UPS ). Most of the UPS we get are called Off line type and are far cheaper than the On line pure sine wave type. The out put of the Off line type UPS is not a sine wave ( the natural waveform of AC voltage ) and strains the Power supply circuit of any device connected to it.
Now if the humming sound is the same irrespective of the volume position, it is a power supply problem. You might be having a leaky rectifier diode or capacitor. First change the diodes and see if its ok then change the main filter capacitors too.

Phillips hts3410d no sound VERY dim led


Have you had any thunderstorms recently in your area? if so, this could be a pulse sent threw your system form an electrical storm. this happens often during dangerous thunderstorm activity. Also, your electrical wiring in your home can produce this as well due to a faulty circuit breaker box or lose ceiling fan hook ups. the best scenario could be a defective product. this way, you can get a full refund or a replacement set up.

Loud whirring noise from home theater receiver


Sounds like a cooling fan is worn out. If the warranty has expired, remove the cover and there should be a cooling fan. Remove the fan. Try cleaning it out with a can of compressed air. If this does not work take the fan to best buy or circuit city and buy a replacement. I hopet his solves your problem!

There are lots of reports of noisy fans. The closest one I can find is to fit a HT-Q70T. It's part no: AH31-00039B. It's a "Motor-Fan C151BK10A2430".
