Write protect how to remove write protection

It could be 1 of the 2 carbon brushes when the autostop protection is activated replace carbon brush cb441 194435-6 is a normal problem when the working hours are arrived ,but if your battery is empty it will stopping at once a protection for li-ion deep discharge protection.

Li ION is the best to have allways 1 of the batteries on the charger ,if working and do not full unload it change after a while before its stopped its better for the expensive li-ion batteries but if forget one batterie to use over time ( because you want to save him well-intentioned ) to use it frequently is better when its to deep discharged it will not working anymore the charger will not accept the battery anymore if its deep discharged , to rewake it preloading it only like this way a safe as possible against fire hazard not use chargers of cars or other tricks do a full working loaden battery from the charger and connect with that other battery connect both to each other with 2 1,5 kwdr wires the full battery with the not accepted not working deep discharged battery that was forget for a long time BEWARE to do only connect a polarisation as the + to the + and the - to the - the poles parrallel connect to each other not longer then 3 minutes after that remove the wires and now put immediately the not working battery on the charger and see that its accepted again, if its not working repeat it one time again , not for 3 times its a real battery problem for garantee or replacement do not work on li ion with battery chargers for a car or other full overpowered chargers without knowledge do not open or disconnect wires inside the battery then the Makita battery is immediatly dead . because of fire hazard protection li ion full battery on empty battery + to + - to - not more then 3 minutes if it still not working within 3 minutes repeat it once again be shure the wires are connected correct from battery to battery to preload if there was an battery problem of an empty battery or dead battery.

If you have a machine with a li-ion battery it MUST me placed as soon as it stopped on the charger and leaf them on the charger and as soon as they get slowing down the rpm of the machine change the battery it has no memory effect or capacity problem Everything opposite to compare with nickel cadmium batteries ,and that because of the old Makita machines with only have 2 battery connectors are now for 60% modified with a 3 (star)contact battery holder by Makita if it was in warranty time by Makita, the switch and contact plate are modified because of the deep discharge protection of makita because it new (star) li-ion batterys have been allways by every brand on protected against discharge with a similar or comparable protection with a small circuit with a refference power on it , a li ion battery can be boosted with a special cadex charger that will bring back the referrenced power so the charger will if boosted working again on the battery . but if your machine shooks has to do with a contact or soldering problem om the switch possibly or to short carbon brushes but not by the battery .

Here is the repair manual. can't find the user manual but you pretty much just put them on your head and the buttons are self-explanatory

Here are instructions on how to remove a glove box on a Honda Accord: 1. Remove these items: Dashboard center lower cover and Passenger's dashboard lower cover. 2. Remove the screws from bottom of the glove box. 3. Wrap a flat-tip screwdriver with protective tape, and apply protective tape around the related parts, to prevent damage. Insert a flat-tip screwdriver in the notch of the cap, and release the hooks by prying up the cap. 4. Remove the screws. 5. Release the hooks, then pull down on the-------------------------------------------------------------------------------------

Either bad batteries or a bad charger. You can use a multimeter to test for DC voltage output in the charger.

Your battery has probably gone and since it is a Li-ion battery, it has sent a signal to the TomTom not to turn on. This is a battery protection circuit in the Li-ion battery. You probably have to replace the battery

Most manufacturers went to 5w30 viscosity oil for mileage gains. I myself would consider a 5w30 synthetic oil to further increase change intervals and protection. A potential milelage gain is a positive side benefit.

How do you know that it has charged to 70% and it is the correct percentage on your Laptop?May be you need some other program that are available on the internet that will tell you the exact charge percentage. Make note that In many ways, lithium-ion is superior to nickel and lead-based chemistries and the applications for lithium-ion batteries are growing as a result. Short battery life in a laptop is mainly cause by heat rather than charge / discharge patterns.Removing the battery from the laptop when running on fixed power protects the battery from heat. Make sure the AC Adapter that you are using [on both laptops] is supplying the correct voltage and if possible check with Load.

I read about the Onboard Emmissions control system sometimes actually causing such wierdness. Apparently, it is so freaking sinsative about getting you the best mileage and protecting the air we breath that it is easily upset. Try rreading the manual about your OB(?) Forgot the third letter. Or, sign up to Alldata. It isn;t free but if you can't find free help, it is worth it. Mike
