Question about Compaq Presario 700 470024-192 Notebook

6 Answers

Notebook smells like burning plastic.

All of a sudden one day the notebook started to run on the battery while it was plugged in. At the same time it started to smell like burning plastic, but no smoke. I shut it down as quick as I could. The next day i started it up but it was once again running on the battery, and the battery was not getting charged. Everytime I plugged it into the outlet it made that smell. I bought a Targus AC70U, thinking it was the stock power cord, but the notebook still smells with the Targus. The new Targus doesn't charge the battery either. Any solutions?

    No I never got it working again. I'm almost tempted to take it apart. What do I have to lose?

    I am having this same problem. It happened about 1 1/2 years ago while my laptop was still under warranty. I shipped it to Fujitsu and they replaced the motherboard. I started noticing my computer running on battery even though it was plugged in about 2 days ago. Today, I was on my computer for a little bit and turned it off when I left. I got back home 20 minutes later, tried to turn my laptop on and it won't even turn on at this point. Wondering if it's the motherboard again or....? Any ideas?

I am having the same problem with my compaq notebook. in fact its the 3rd time it has happened. I kept ordering new cords thinking that was the problem.

The part that plugs into the computer itself is the part that is melting. the glue from inside of it is coming out of the thing that plugs into the computer.

Any ideas of what to do?

The 700 Presarios were notorious for Trace shorts at the Jack and F1.. There is a work around but these were not a safe unit as they can arc and smolder burning a hole in the systemboard. We reapired a ton of them back in the day.

The Averatec 3200 PC Notebook is equip with a power module that connect the ac power adapter to the notebook and charges the battery. When this small circuit board shorts or become defective in any way it fails to charge the battery and you will smell smoke due to the poor connection. By replacing the power module it will resolve your isssue. RON

The Ferrari draws more power than the puny coaxial power jack can handle. Mine burned to toast and I soldered an automotive two-conductor flat connector to the board, pigtailing it out of the hole where the jack used to be. The pigtail may be ugly, but I have no more power issues.

If the new Targus charger is really rated correctly for your laptop, your battery isn?t charging and you smell the burning plastic coming from the laptop when you plug it in that is a fairly dangerous situation and you shouldn?t plug it back in anymore. The power from the charger runs through a PCB board which distributes power to other components in your laptop. I suspect one of the components (probably a capacitor) had a catastrophic failure and is the cause of the smell and the lack of battery charging. Once again assuming that the Targus is the correct one for your laptop current you probably have a laptop damaged beyond home or economical repair.

SOURCE: Notebook smells like burning plastic.

cud be your onboard voltage regulator for the battery charging. if you remove the battery and use the external power source does it smell also?
if the battery charges normal out of the unit, and the laptop works well with the AC power unit without the battery, then it's your voltage regulator for the batt charging

SOURCE: plugged in, not charging

As said before, the voltage and current is the most important thing to go after. I believe the common voltage is 9v for european laptops, but check your laptop's guide, and it will say exactly what it can take. Take care the next time you buy an adapter. Also, so adapaters don't charge, they only let you turn it on, you need to pay more for a charger. Good luck.

SOURCE: Armada E500 notebook Power button not responding.

Unless you took the batteries to a service center, I am dubious about your ability to confirm the main battery is holding a charge. The average lifespan of these kinds of batteries range between 3-5 years and is likely at the end of its lifespan. This would explain the diminishing performance over the last year if there were significant power or power circuit issues, they would likely be observed on AC power as well. This model of laptop requires the battery calibration utility be run in order for the laptop use the battery. In fact, the battery can show a full charge and still not function if the utility and battery have not been properly configured.. . . instructions on HOW TO do this below. If this doesn't FixYa then the battery will need to be replaced (links to replacement sources) www.BatteriesOvernight.com/HP-Batteries,----- OR --- www.new-laptop-battery.com/Compaq/?Compaq-Armada-E500-battery.htm. You will still have to run the configuration utility when you receive your new battery.
Link to Armada e500 manuals:http://bizsupport2.austin.hp.com/bc/docs/support/SupportManual/c01124216/c01124216.pdf
How to run config utility: Standby and hibernation must be disabled for the battery to discharge completely and shut off. To use the Battery Calibration utility, first identify whether the battery requires calibration by launching the Power Management applet as described above. On the Battery Calibration tab, all installed batteries will be displayed in the primary list box. Next to each battery name will be an indication of whether calibration is required for that battery. If calibration is necessary, the phrase “Needs Calibration” will be displayed. Select the battery to be calibrated, and click the Start Calibration button. During calibration, the utility will display an icon on the Windows System Tray to indicate that calibration is in progress. Each phase of calibration (charging or discharging) will also be displayed. Calibration is complete when the icon is no longer displayed in the System Tray. Battery calibration requires several hours for completion. If you choose to continue using the computer during the calibration process, it must be connected to AC power. The calibration process must be allowed to finish without interruption. Performing any of the following actions will prematurely terminate calibration:  Clicking the Stop Calibrating button in the Compaq Power tab.  Unplugging AC power from the computer.  Unplugging the calibrating battery. (This action may result in data loss if a second battery is not installed.)  Undocking the computer.  Pressing the power or standby button.  Powering down or suspending the machine by using the Windows menu. IMPORTANT: If the calibration process is interrupted, it cannot be resumed. You must restart the computer and start the process again.
CALIBRATING WITHOUT THE UTILITY To calibrate a battery on computers without the battery calibration utility, complete the following steps: 1. Remove the second battery, if present, so that only the battery needing calibration remains in the computer. 2. Dock the computer or connect the computer to AC power. 3. Turn on the computer. 4. Check the current battery capacity level by positioning the cursor over the battery icon in the system tray. 5. Allow the battery to charge to 100%. You may use the computer, but the recharging process will require more time. 6. Set the system to “drain” mode on the battery conservation settings by pressing Fn+F7, or select Start > Settings > Control Panel > Power (or Compaq Power in Windows NT). 7. Undock the computer or disconnect the computer from AC power. 8. Restart the computer in MS-DOS mode by clicking Start > Shut Down > Restart the Computer in MS-DOS Mode > OK. 9. Allow the computer to discharge until it shuts off. 10. Dock the computer or reconnect AC power. 11. Allow the computer to charge again to 100% as in Step 5.

Maytag Neptune MAH5500 smelled like burning plastic at the end of the cycle. (The whole basement smelled bad.) The smell seemed to be coming from the plastic part at the top where it latches.


Tub bearings get worse, if they faulty, the machine would be noisy and getting louder. Sudden burning smells usually mean an electrical failure of a component but if this has stopped and the machine is working properly, its possible that something has got caught up in the rim of the tub or gasket area and during spin it has got "burnt" by being dragged around the edge. Have a close look at your clothes that were washed on that day for signs of burning or damage and around the top at leading edges of the tub for signs of melting or damage.

Low humming noise and burnt plastic smell coming from 1990 acura integra


Jennifer what type of timing belt does your engine use ?
Is it Nylon ? When was the last time you had it changed ?
Burning plastic smell may be being caused by the timing belt bearing runners seizing and the belt is getting hot .
If the belt is due to snap you could cause a lot of damage to the engine if it breaks.
Might be worth getting a mechanics advice on this as a possible cause

We have an Acer Aspire 5810TZ. It will not run unless the AC is plugged in. It shows 95% battery but not charging.


Um, no... I am seeing the exact same issue and my battery is not dead. System says it is 100% charged and the system was just running on battery for 2 hours the previous day now suddenly mine will not run on battery at all. I am starting to smell a product defect issue here but can't get anyone to talk to me about it at that level.

Take out the battery and run just on external power, see if the smell goes away. If it does, check to see if there is a recall on that battery.
