Samsung Series 5 NP535U3C won't charge or turn on

I have this problem with my girlfriends laptop.

She broke her charger for it, used the battery almost to the end and we kinda forgot to order new charger. After 2 months we got new one.
She plugged charger in and charging light lit and pushed the power button but nothing happened. After that it won't charge and won't turn on.

I tried that bottom pinhole thingie, but nothing happened. Only red flash and that's it. I have opened laptop covers, unplugged and plugged in battery wire but still nothing.

Any ideas how I can fix this? I really want to get it running again, so my girlfriend won't steal my PC never again.

 

First, try plugging it in and leaving it for several hours so the system has a chance to try to get some life into what may now be a dead battery (Lithium batteries don't like being left completely discharged).

If that doesn't work then you can see if the system starts if the battery is disconnected. If it does then you know the PSU is working. If it doesn't then the problem might be one of (a) the computer refuses to start without a battery connected; (b) the new charger is defective; or (c) the power socket on the computer is damaged (or the charger doesn't connect properly - make sure the plug is fully pushed in). If you have a multimeter then you can check if the charger is providing the required voltage.

Thanks for the answer, I really appreciate it!

I have left it to charge for over night, but nothing is really happening. I have tried to put some life to lithium battery (this model has built-in battery, so its not removable, if you don't take it apart) from low-voltage source, but next thing to do is to take multimeter and check, if there is any voltages coming from charger or from the battery. Should I try to order new powerjack from ebay, if there is everything else fine after checking voltages etc.?

 

OK. You've already tried the overnight charge without any good effect. Re-reading your first post I see "She plugged charger in and charging light lit and pushed the power button but nothing happened. After that it won't charge and won't turn on.".

This suggests that the power jack is OK because the light brielfy came on but what we don't know is whether the brief sign of power was terminated by the charger or the computer. I would first check the former with a meter. When it is plugged in to the AC socket there should be about 19V between the inside and the outside of the DC plug (+ve is on the inside). There's the possibility that there was a defect in the PSU which caused it to die after that brief hint of power.

I can't think of a good reason why a sick battery would prevent the computer from booting but there are some aspects of computer hardware design which leave me baffled. someone may have decided that a battery with zero charge represents an explosion risk so the system refuses to charge it. However, given that the battery calibration process also drains a battery but then recharges it, that logic doesn't work unless the system can detect that the battery left without charge has become defective (which is possible). You indicated that you can disconnect the battery. if so try disconnecting it then plugging in the PSU and seeing if the computer will start.

The battery is part No BA43-00336A.

I already tried taking battery off entirely and then boot with PSU, but it won't start without battery either. I didn't get multimeter to test it, so I will borrow one from my friend and do some tests with it. This charger has really tiny center hole (+ side), so how I can measure its voltage? Is there any way to measure, is there going any voltages to the motherboard, nor anywhere inside the computer? I have not used multimeter before, so maybe I have to work with my friend (he is electrician).

 

I've tested the Samsung Series 9 PSU (probably the same as your with the small plug) by partly straightening a paper clip and putting it into the centre hole. The voltage can then be measured between this and the outer barrel of the plug (with the PSU plugged in to the mains). However, if you don't have experience with using the multimeter then it would be sensible to take the PSU to your electrician friend.

If the PSU is confirmed to be OK then it is possible to check whether power is getting through to the main board but this may require a major strip down of the computer.

Hello John, I finally got my friend here with multimeter and we checked several things:
1. PSU is fine, it outputs as much voltages and amps as it is supposed to output.
2. Voltages are coming through from plug to motherboard socket.
3. Lithium battery is completly dead. and there isnt any voltages coming to batterysocket inside laptop.

So, should I consider to buy new battery, since you apparently can't charge battery any other way.

 

I wonder if there's no voltage on the battery socket in the computer because whatever chip controls the battery usage probably wants to talk to the battery before sending any power (if it is needed).

It's probably the battery and you need to have a good battery before you can proceed. Batteries left in a fully discharged condition can completely die.

John

 

Sorry for late response, but I left this laptop behind and have been using my old laptop which I found from back of my closet. Now I finally got this Samsung laptop in my hands again with brand new battery. I installed it in, but there is now a new problem. Whenever I plug charger in, it shows RED light on battery indicator, which should be green and it wont start without charger on. Should I try to reinstall battery if its wrongly installed, or what can be the problem?

 

Run BatteryInfoView and see what it says about the battery. Is the battery detected?

John

 

I ran into other problems while trying to get it on. Firstly, Windows logon screen stuck while loading and now it wont even get on. There isnt any lights coming on when I plug charger in and pinhole thingy at bottom does nothing. Im speechless...

 

I would suspect that either the charger or the power circuit is dead.

Maybe you had managed to previously boot the computer with the power in the new battery but if that is now run down and now power is getting through then there's no hint of life.

While trying another PSU isn't very expensive (if you look for one of the "compatible" PSUs), the easiest way to check for a power circuit problem is to replace the mainboard, which is expensive. Sometimes, it is reasonably easy for someone familiar with electronics repairs to spot a dead component and replace it, but that needs the required skills and equipment.

I apologise for not being more helpful. Maybe someone else has some suggestions.

John

 

From early on in this thread it sounds like the charger itself is bad. A MM will show voltage, and possibly amperage as ok there can be several other issues. Primarily with the Caps, rarely do these go in the laptop itself but it has happened. What you will see is the power brick by itself look good but as soon as it is under load it will start having issues either supplying clean power or even folding all together.

Now if the brick is bad it could have taken the old battery with it, try a new one though ASAP. Reason being is if it is the issue it could rapidly take your new battery out.

 

This Battery have a circuit protect and charging board inside the battery pack. See:

I have a NP530U3C-AD5BR Samsung Ultrabook. Despite being on the energy he will not charge batteries. I have changed the batteries with new ones but this problem persist.
This ultrabook use 4 Cells of LiPolymer battery amounting to 45Wh each cell is 3,7V. There are a board into the packet that control charging, temperature, overcharging, undercharging using a Maxim Max1788 microcontroler. There are 9 wires. 6 wires (3 red and 3 black) that I thing that are for power supply. There are 3 wires, 2 are SMData e SMClock for SMBus V1.1 comunication to the motherboard.
I don't know what happen because my ultrabook was working normally until when I left it for 2 months without connecting it to light. After that he never charged the battery.

Since there is no light, power or otherwise, activity this is why the power brick itself is suspect.

 

Hello, i have "same" problem, the laptop won´t charge or work with battery, only appens after this: i let the laptop fall in to the floor, it kiks on the fall with power jack side coner...before that, works fine, battery and power cable...all good... now only work by power cable, the battery won´t charge and the led light blinks (flash): green/red...

i took out the battery like it show on this picture above, i all so measure each contact of the battery, the contacts i measure is like it show on this picture:



Each have 3,78v ( more or less) all 4 makes: 15,12v (more or less)... it the battery good? or is the board that control the battery born out... what else can be done?

By the way thanks for all post sir: John Ratsey very good information.

in the end of all, can you tell how do teste this board:



becasuse on each battery have 3,78v, so i do guess something is not doing is job on this board above, can you please tell me how to test this board.... please help.

Best regards

 

Probability, with this and other Samsung integrated batteries, is the board is protecting the system from a fire. If a cell by natural drop off or just a jolt and quick disconnect, drops below a certain level the board cuts out usage of the entire battery. With LI's if the voltage drops too low this is a signal of the cell failing and about to catch fire either by a charge or discharge. If my memory serves the catastrophic level is 2.4v but I could easily be wrong here. My point though is I think there are two issues;

1.) the set point is too high, where it could be as 2.5v they could have it at 3.0v per cell. Also since this active monitoring is in place there is a small drain. There should be a cutoff of the monitoring before the drain kills the cells to the board.

2.) the board should reset the cells once it sees normal levels. Now at a top charge those same cells should show 4.2v or there about but still at 3.7 the cell leveling should kick in and try and regain the pack. It should be known that with advanced cell leveling it could take 48 hours or more to heal a pack. Also this assumes a cell leveling circuitries existence.

 

first of all, thank you for reply...

already I bought a new battery,
now the most important and my afraid is,
can it burn this new battery, i mean,
it's safe install a new battery without the risk of burn it?
there is any test on the main board (connector) to battery
to ensure that there is no problem to plug in new battery...??
th laptop works fine without battery, the led of battery goes green, and the laptop works fine, when i plug the old battery the led light of it, blinks between: gree/red, if i remove the battery, plug the wire start the laptop all works fine, and the battery led light pass to steady green...

once again thanks for all support... i just need to know it is safe to plug new samsung battery, i mean plug & play, and the lap wont burn the new battery? it is completely safe?

Best regards to you all, i all ready have new battery by samsung saler.

 

There is no 100% safe guard but of course try not to drop or severe shock the system and keep it well charged.

 

Thank you for reply!

Updateing:

i just plug the new battery, WITHOUT AC ADAPTER PLUG, only plug the battery, and the laptop wont work, wont switch on, by just plugin the new battery, i do guess the new battery have some energy, i guess, or im rong, i must charge the new battery firts, because is new, please help?

the laptop wont power up with the new battery, i just install the new battery, press the power button, and nothing appens... what else can be done, please, teste or else?

Once again, thanks for all reply and help. Best regards.

 

On the Series 9 notebooks the battery has a built-in disconnect switch so that it won't discharge during storage. This switch is connected automatically when the battery receives AC power.

Does your notebook have a similar feature?

John

 

Thank you for repply

yes, the battery have small switch (pinhole), i press it and then power button and nothing... wont power up by battery use mode...
i never try to connect the charger for fear of burning the new battery... do i must connect the ac charger to get power from battery? i guess no need to!

what can be test with multimeter to know what is causing this issue? here some pictures of motherborad, it is not my motherboard, but is the same board that i have:

front image:


i plug the ac adapter and measure the battery connector the 3 pins that connetcs to 3 red wires on battery, each one have 3,5v

what else can be test?

back side:



Please help, if you may.

Regards

 

Pressing the switch disconnects the battery. Power needs to be applied in order for the switch to reconnect. I first discovered that when unboxing a Samsung NP900X4C: It would not turn on until I had connected the PSU.

You have little choice but connect the PSU in order to connect the battery. I would expect the battery itself has protection against getting damaged if the power supply has a problem because of the potential consequences.

John

 

Yes, you are absolutely right.

The reactivation of the battery is only possibel by plugin the PSU to laptop , i confirm that, and as you metion, the switch (pinhole) on teh battery only disconnects the battery to prevente eletric damage to the mainboard or battery it self, and to reactivated the battery it is only possibel by plugin the PSU to laptop, if not the battery wont turn or be reactivated.

the mirco switch it is allso to shut off the battery to power save or for emergency protection, when you drop some liquid or else on laptop...

so in order to change the memory or battery, press the mirco switch on the battery, is the small pinhole in the middel of battery, by doing this it prevents damage on any eletric system, if not, well maybe work or not, anyway, this pinhole disconnects the battery nothing more than that, to prevent eletric shock to mainboad or battery it self...

the reactivation of the battery is only possibel by plugin the PSU to laptop, if not, the battery will not be reactivated.


Thank you for all your repply.
i do hope this it will be usefull to you all in the future.

Best regards
