Packard Bell Easynote L4 Intermittent Power Problem
I have a laptop as above...intermittently it won't power up. When it does power up it works fine and normal and doesn't cut-out, however after powering down...sometimes (and it's getting more frequent) it won't power up at all....there's no sign of life at all i.e. if the power supply is plugged in, it doesn't indicate that it's charging and it won't power from the battery. When it does start it can work on the battery for a normal amount of time, suggesting that the battery is OK. Do you know if the input dc socket is prone to being a problem....could it be something more sinister???
Thanks in advance.

Your first problem is to find out why the intermittent no-power problem. Honestly, that sounds like a loose conmnection somewhere. check all your grounds for clean and tight conditions Also, battery connections and alternator connections. Double check your power distribution center for any loose wires or poor connections. Once you solve that problem, then you can diagnose the other problems with poor idle and temp. gauge.
Take out the AC power jack and then remove the laptop battery. Plug AC power back in and see if the laptop will turn on. If it turns on let it boot the operating system and then shut down as normal, remove the power cord and reinsert the battery and again see if it will switch on. If it does then there has been a glitch with the battery. If it doesn't then there is a problem with the battery.
If the laptop won't switch on either with or without the battery then there is a possibility that the motherboard has developed a problem.
hi i would recommend the best is to take ur laptop to ur service provider since u haven't mentioned ur company name if ur laptop has a warranty then they will solve the problem for free n they won't charge u for that but if ur laptop doesn't has the warranty then they will charge u a minimum of 100-200 rupees and if its due to a software problem then try the best is system restore it restores ur system to an earlier time when ur windows worked fine but best is the above solution and thanks for posting ur problem if there are any further problem regarding the above topic then mention it in brief with warm regards- bonefirediv
If the power supply does not run the laptop without the battery, then the problem is the jack in the laptop, over time the plug breaks free of the motherboard causing intermittent operation or no power. If the power supply runs the laptop without the battery, it is the charging circuits on the motherboard that is the issue.

Here are the problems…
Above about 6000 RPM the ignition will intermittently cut out. It doesn’t do it all the time. The higher the RPM the more it tends to cut out. Reducing RPM brings the lights back to bright.
Above about 6000 RPM the lights start to dim intermittently. The higher the RPM the dimmer they get to where the lights almost go out. The engine runs fine if the RPM is reduced.
The tachometer records some very high RPMS when the system starts to act up. Max RPM recorded is 19999 which is totally unreasonable.
I am looking for some assistance in troubleshooting my electrical system and how to isolate the problem(s).,Start by disconnecting the cables from the generator coils and start up your engine. Problem still there?
Do this to find out if your problems stems from the power side or the ignition side. If bike now runs fine, I'd look at the voltage regulator.
Have you checked that all your connectors are ok? A grounding problem with a somewhat loose connector would be vibration sensitive, hence the problems at higher rpm. Is your stator plate securely fastened? Is your engine grounded to chassis? There might be a loose fastening in one of you engine mounts.
