Hey guys, I had a surface 7+ pro come in for a cracked screen that held a charge. After replacing the screen the battery refuses to charge. I tried to use a dc supply to wake the battery up but it takes no current at all. Tablet is working fine on charger / usb c. The only thing I can think is the heat from the hot plate did something to the battery during the screen removal.

Rule out the battery by sourcing another from Mobile Sentrix or Amazon. -
Good stuff. Thanks for the update.
On the removal, try dipping your plastic cards / plastic tools into a bit of alcohol while carving out the lcd. It helps a great deal to dissolve the glue. We do this for the imacs with the glued screen and their wheel tool. Expedites the process.Comment

Hello,

I am a pro and I have a problem that I have never seen despite my 7.5 years of experience on my own and my thousands of repairs, on a customer's Dell G3 15 3500.
On this PC I have already changed the complete palmrest because the keyboard was no longer working properly.
I also changed the screen because the PC fell and the screen was broken.
I changed the battery with a new and original battery.
I also had corrosion/oxidation on the... -
Hi, my dear friends., Maybe this might be a stupid question or something I missed or do not know. I have 2 MacBook Air A2681 (Indentical color & EMC #), both LCD screens broken. Before ordering the LCD Screens I confirmed both worked with their respective batteries & AC Adapters, & they did 100%. The LCD Screens came in today & I replaced LCD for the 1st A2681. (Removed Battery Terminal cable for both Laptops before installation of LCDs). Perfect Screen & Booted up fine. But it did not work with battery. I checked the battery connector & it was seated in well/perfectly.... -
Hello everyone,
Mark and model: ASUS X571
Symptoms: not turning on. There is only the LED battery indicator working. The owner of the laptop told me this problem arrived one week after having changed the battery. He then managed to power on the laptop only once, and then it never powered on again.
Tests already made:
- Battery is charging when laptop is plugged in. The LED battery indicator turns white after a couple of hours of charge, indicating that battery is fully charged. However, laptop won't turn on anyway, with or without AC plug.
- I have removed... -
The ISL88739 & ISL88739AHRZ are a highly versatile combo battery charger
configurable for operating as either a Hybrid Power Boost (HPB)
charger or a Narrow VDC (NVDC) charger, supporting 2-, 3-, or
4-cell batteries. Both configurations allow the battery to work with
the adapter together to supply the system load when it exceeds
the adapter capability, referred to as system Turbo mode. HPB
charger configuration reverse-boosts battery energy to the system
bus to help the adapter provide the system power in Turbo mode.
NVDC charger configuration...11-05-2024, 03:28 PM -
Hi, so the old battery was getting error stated it's capacity is starting too get low and should be replaced, so the customer bought a new one and replaced it, but the new battery was also getting this notice that it's capacity is getting low and should be replaced, so i took the laptop for testing and the battery is charging at the terminal at 8.03V , the voltage of the battery is 7.7V, and drawing around 600mA when charger is put and the laptop is off...so that should be ok... but the bios system test doesn't recognize the battery and can't do the battery test and so is the hp battery manager,...
