The power pack is going off when connected to the system

If your BMW E90 has no spark on coil packs number 3 and 4 but you get a spark when you take the coil pack from number 3 or 4 and put it on another cylinder, it's likely that the issue is with the wiring or connections to those particular coil packs. Here are a few things to check:

1. Wiring Harness: Check the wiring harness that connects to the coil packs for any signs of damage, such as frayed wires or loose connections. Repair or replace any damaged wiring as needed.
2. Ignition Control Module: The ignition control module (ICM) is responsible for sending signals to the coil packs to create spark. Check the ICM for any signs of damage or wear, and test it to ensure it's functioning correctly. If it's faulty, replace it.
3. Ground Connections: Check the ground connections for the coil packs to ensure they are properly connected and not corroded. Clean or replace any corroded connections.
4. Power Supply: Check the power supply to the coil packs to ensure it's functioning correctly. If the power supply is faulty, it can cause issues with spark.

If none of these solutions fix the problem, it may be best to have the car inspected by a professional mechanic who can diagnose and repair any more serious issues with the ignition system.

we have installed a new ups but the battery light indicates red light even though its on charge

Working with the bulbs can cause other bulbs to go out.
Malibu suggests turn power pack off when replacing bulbs.
Also connections get loose and need to be re-attached.

most power supply units will fit you can get a larger wattage output eg: heavy duty if you have added any more devices to your computer more RAM,a larger hard drive,more cd/dvd drives these added will put a greater need for wattage output on the PSU
you should check all the electrical connections before you make a decision and make sure they are the same as as the ones that you will need to run your computer also
check the measurements inside the frame to make absolutely sure it will fit
you can get lots of PSU

Hi! TRY THESE TO SEE IF WE CAN GET YOU POWERED UP! :)



Confirm the system is not in HOLD mode
Make sure the PSP system is not in Hold Mode (in the down position). Slide the Power/Hold switch up to clear Hold Mode. Or try sliding the Power/Hold switch up and holding it there until the power indicator light turns off and the PSP system is completely turned off. Then try turning the PSP on again.

• Confirm the backlight is ON
  Make sure the LCD screen's backlight is not turned off. If it is, press any button to turn ON the backlight.
  
  
• Confirm use of only licensed products (AC Adaptor, battery pack and charger)
  The AC Adaptor, battery pack and battery charger must be licensed for use with the PSP system. All licensed products for use with the PSP will have the following logos displayed directly on the product and/or the packaging:
  
  If any of the products you are using does not have these logos on them, we recommend that you immediately discontinue the use of these products, as they void the PSP system's warranty, and can cause damage to the system. See compatible peripherals for the PSP system for a full list of supported products.
  There are some products that can be used with the PSP system that may not display our logos. Products such as San Disk 1GB Memory Sticks, or various USB cables, needs only to be genuinely certified. Look for the genuine certified logos on these products or contact the company which manufactures these products for more information.
  
  
• Confirm the battery pack is correctly inserted
  Make sure the battery pack is in its proper position (see inserting the battery pack for details).
  
  
• Try the battery pack only
  Unplug the AC adaptor from the PSP system. Make sure a charged PSP battery pack is inserted inside the PSP system. Turn on the unit. If you get power, then the problem may be with the AC adaptor and power cord.
  
  
• Try the battery pack in a different PSP system
  If possible, try your PSP battery pack in a different PSP system. If your battery works on a different PSP system, it may indicate an issue with your PSP system.
  
  
• Try a different PSP battery pack
  If possible, try a different battery in your PSP system. If a different battery pack does work on your PSP system, it may indicate an issue with the original battery pack.
  
  
• Try the AC adaptor and the PSP battery pack
  Insert the battery pack and plug in the AC adaptor. If you still do not get any power, your PSP system may need to be sent in for service (see PSP Service for details).
  
  
• Try the AC adaptor / power cord only
  Turn off the PSP system, unplug the AC adaptor, and remove the battery. Now plug in the AC adaptor to the PSP system with the battery removed. Confirm the AC adaptor and power cord are firmly connected to each other. Now make sure they are also firmly connected to the PSP system and the electrical outlet.
  If the PSP system powers on, the battery may need to be replaced.
  
  
• Check AC adaptor and power cord for damage
  Visually inspect the AC adaptor and the power cord for damage. Do not use if frayed, cut, or damaged in any way.
  
  
• Check the electrical outlet
  Confirm the electrical outlet that you are using is active (receiving power). Try using a different electrical outlet.
  
  
• Try a different AC adaptor and power cord
  If possible, try a different AC adaptor and power cord. If a different AC adaptor and power cord does not work, the PSP system may need to be sent in for service (see PSP Service for details).
  
  
• Confirm no unauthorized system software or downloads were used
  Confirm that you have not used any unauthorized system software updates or downloads on the PSP system. Use of such unauthorized firmware updates voids the warranty and can damage the PSP system.
  
  
• WLAN turned off
  Make sure the wireless (WLAN) network function is not in use while charging. The battery pack cannot be recharged when the WLAN function is being used.
  
  
• Power surge
  If you experienced a power surge, shortage, or a lightning storm in your geographical area recently, this may have affected the PSP system's power supply. Please contact Consumer Services below for information.

If nothing at all works then perhaps you have no power to the system.

Check that the powerpack is getting power (does it hum or get warm when plugged into the mains socket?) Check all connections to the power pack and back of laptop.

Try taking the battery out and powering up on only the power pack

Do you know anyone with a similar laptop that you could swap power pack with?

yes if you have the power pack it acts as a extra charging system giving you more time to entertain

Probably a poor power connection either where the AC pack goes in to the wall (probably powerbar!) or where the plug from the power pack goes into the unit. Wiggle the various connectors to see which one solves the problem. As a last resort you may have a faulty power pack (try ask a dealer or friend to test your system on their power pack).
