Alienware Laptop vs POWER SURGE - Can I Fix It? I paid $300 for a broken Alienware Gaming Laptop that the seller said never turned back on after a power surge. The laptop doesn't seem to charge so of course I'll be taking it apart to see what I can figure out and if I can get it working again.

Regarding laptop repairs, There are many custom-made chips that you never ever find anything on the net. The biggest problem is the spareparts. You cannot find them either. So, laptop repair means having alot of doner boards. For apple computers that might be possible but for other brands that is just not possible. BGA is a big problem. Even if you fix, you might damage components on the other side. It is double sided and other BGAs on the other side might be affected.

Regarding the battery, it is usual for the manufacturer to specify the nominal voltage (in your case 11.4V), which is simply kinda an "average" value, used to calculate the amount of energy stored in Wh (proper way is to integrate the voltage curve from full to empty, but an average works fine), just doing [nominal voltage] x [cell capacity in Ah]. The usual nominal voltage por LiPo and LiIon batteries is 3.7 volts per cell, so 11.1V on a 3S battery. When dealing with HV batteries, this nominal voltage can be a tad higher, so it is not rare to see values like 3.8V/cell (so 11.4V). However since the topping voltage is 12.6V from the schematic I assume in this case alienware is overly optimistic, because that is not HV topping voltage, is standard full cell voltage (4.2V/cell). That battery should probably have a nominal voltage of 11.1V too in order to give a proper Wh estimate, but w/e. So... well, both of the batteries looked fine to me. I see you traced down a problem with the charging IC and replaced it. Sadly no happy ending!

Is it possible that a resistor leading to the 5V was broken in the the surge? I dealt with a board at work earlier that had to many volts put through it and caused the resistors to crack. Of course it would be hell to track down a pin size hole or hair line fracture on *at least* one of several resistors. Are you able to check any of the parts connected to that leg of the chip using the schematic? Or would that be a waste of time?

It would have been nice to know what type of power surge you were having to deal with since it would have given you a better picture of what you might have been facing but this is just the breaks sometimes most people don't even think of what may have surged the line.... my experience is a direct strike is pretty much a futile repair attempt, a brush where you were close to the strike like lighting not striking the power line directly but close enough to induce a high voltage on the line or you are further down the line from the strike... sometimes you may fix it. and this is the area that a good surge protector can help protect you. Or the power company drops a 220 line on your 110 and I have personally had that happen odds are much more in your favor to repair it... and then you can have a Brown out and sometimes that can fry you electronics as well and odds are pretty much in your favor to repair it... all was ask if you can, but buying on eBay your often left in uncharted territory.

But that's a very small chip. I'm almost a complete beginner and was still able to reball a chip of roughly that same size using a 5 dollar kit from Aliexpress. The chip I reballed was an ARM from a JDM-040 PS4 controller board. It took only 30 minutes and one failed attempt because I burned a chip from a practice board at 480ºC (the right amount of heat was 270ºC with low melt solder balls and a universal stencil from the reballing kit).

@dedr4m Жыл бұрын

Also many laptops use what they call LiHV cells that are regular Lithium cells with chemistries to increase service life when charged to 4.4V/cell with a total of 13.2V... Though I'm charging a modded phone battery moto-mod attachment where I use a 4.2V cell at 4.35V and researching let me know that the 4.4v is an upper-limit thing that gives more capacity with reducing capacity by a third (200 cycles versus 300 cycles service life). Most laptops that have LiHV cells seems to report a 12.9v peak charging when polling the device directly (Something Linux allows in most cases, except peasant-grade HP laptops et least) It seems that they choose 4.3v/cell for some safety margin and to give a few more cycles service life. It also explains part of why laptop batteries from 2008 can often still give 80% its design capacity and yet a battery from laptops of the 2016 and newer often don't hold charge well or swell up.

There is zero guarantee these things are fixable, and like with this board, even re-selling for spares is gonna be tough as you have no idea what is still useable other than the most obvious things that are not electrical. Here in the UK, you would take a risk at £100 maybe, but no way would you spend £300 on a spares or repair item, even if it's potential value is £700. It's like a form of gambling.

Reply to 13:55. As far as I know, there is not a single modern laptop which requires a battery to run. Power cable should be just fine. Actually, many batteries go bad over time, and require you to either unplug it, or replace it if you want good performance on your laptop. Since whenever the battery is low, your computer will most likely attempt to preserve the power longer by not using as much power on the cpu and gpu. Leaving you with a worse performance overall. Batteries going bad looks simular to regular low battery to the operating system. I personally had an issue with my laptop, where it kept trying to use battery settings even though it showed as fully charged. So I ended up unplugging mine and only ever using the cable to avoid the performance hickups.

Most of the time they will save the device but it isn't 100%. While 99% of the time the brick is what gets killed there is a good 1% chance it gets through to the other components. It also is commonly an age issue, older power bricks are more likely to fail. That 1% change is why I have all my high dollar stuff like TV, game console, PC all plugged into a UPS. They prevent both the low power and power surge from killing anything.

@dedr4m Жыл бұрын

The PSU is supposed to have built in surge suppression unless it's a cheap knockoff, however the output of the PSU has no surge suppression, it's what those MOSFETS are partially for and the fact the typical input capacitances are around 220uF max thus a surge of less than a few miliseconds at maybe 10+ amps (the power brick will have over 2200uF of bulk capacitance for smoothing power to the typical 19V, edit: That means the capacitors will handle and smooth the millisecond surges well in excess of at least twice the rated max current as that's the max continuous current of the power supply) The mains surge is always isolated from the laptop unless the knockoff has no insulation tape between the mains and laptop side (See Diode Gone Wild and his videos on dodgy chargers). That is, if the PSU can supply 12A continuous and the laptop is rated to pull no more than 4.35A (assuming all the USB is in use, a power hungry HDD, max RAM and running a stress test), should the laptop have a fault that draws more than 4.35A max, say 10A.... whatever is causing that will have 5.65A going through it until something gives, be it the component at fault, a fuse, an active safety current limiting sense circuit trips shutting off the damaged part or the whole laptop (i.e. a faulty GPU could either turn off or the whole laptop turns off, the manufacturer decides). Lesson: Be very careful to get a genuine original power supply or one that is reputable and is of a known genuine source, there's plenty of knock-offs that look genuine (again, see Diode Gone Wild's videos, many look genuine and yet almost guaranteed to kill the unsuspecting user because the "safe side" is essentially shorted to mains!!!). Also, things do sometimes just fail, I had a laptop hinge cut into the display cable shorting 19V to the backlight enable wire killing the Embedded Controller and thus wrote the whole laptop off (The BGA part that is suspected in this video, could be a similar cause)

The laptop i had came into my shop and ended up having a short on one of the coils near where you were working, 0.7ohms resistance to GND. when i injected voltage at that coil, a cap lit up on my thermal cam. sort of near the area but near what looks to be the firmware chip, there are two caps next to it. After removing the cap, the laptop came back to life. i posted a link in my comment to a google review for my business showing the laptop i worked on. im guessing that may have been the reason youtube pulled my comment, or i just hit "reply" and exited too quick, haha if you search CF Micro Repairs on google, youll find my business and the first review is the same laptop, but in white. also, the video was very well done and kept me hooked the entire time, hats off to you steve! I hope any of this info helps for this or future repairs
