I buy a new laptop battery from we replaced the battery with the new 9 cell one . Unfortunately, the Toshiba laptop says that the battery is not connected. Sometimes when I reinstall the battery it says connected but not charging.....then will go back to battery not connected. I thought that this might just be the computer, but when I feel the charger it is not getting warm which is an indication that the unit is not charging. I then let the computer run on battery power until it when into sleep mode and then tried to recharge it. I received the same messages. I need help, any suggestions? When I put the old battery back in everything works fine.'
i contact the seller,they would like to resend me a new one,but i urgent
so any suggestion?

— short expert summary and next steps.

Because the original pack works but the new PA3536U-1brs sometimes appears as "not connected" or "connected but not charging", the issue is most likely a recognition/communication or protection-circuit problem inside the replacement pack rather than the laptop adapter. Building on the ideas from and the replacement-experience note from , try these targeted steps before accepting an RMA:

  1. Reset the laptop's embedded controller (EC): shut down, unplug AC, remove the battery, then press-and-hold the power button for 30 seconds. Reconnect AC only and boot to BIOS/OS, then shut down and reinsert the battery. This often clears stale battery-state information that prevents correct detection.

  2. Force Windows (if applicable) to re-detect the battery: open Device Manager -> Batteries -> uninstall the "Microsoft ACPI-Compliant Control Method Battery" entries, then scan for hardware changes or reboot. This resets the ACPI battery interface.

  3. Check BIOS detection and consider a BIOS update only from Toshiba support: if the pack is not shown correctly in BIOS/UEFI the problem is at the firmware/communication level, not Windows.

  4. Quick physical checks not already covered: confirm there is no shipping tape or plastic over the pack contacts, ensure the pack fully latches, and look for any bent pins or misalignment that would cause intermittent seating.

If those steps fail, ask the seller for a tested replacement (confirm it explicitly supports PA3536U-1brs ID/communication) or an OEM-equivalent. For safety, do not open or try to repair the battery pack. If you need the laptop urgently, keep using the original battery or run on AC until a guaranteed-working replacement arrives.

Had the same problem with my Dell laptop. Finally, after changing a couple of new batteries it worked. Infuriating but what can one do. Sometimes they have a mind of their own.

Well, for one, if you are good with a multi meter you can check to see if the contacts are working and charging. Check the , the contacts of the unit and the contacts of the battery---make sure the pins have ample spring or resistance enough to make good contact (they get worn).

You can see if the unit runs the battery just on AC.

You can ask the client how old the unit is and if they leave the battery in every time they hook up to the wall as well---in this case the battery probably had all the life cycles it had available used up---especially if the unit has some age and/or wear or both. Some computer systems cycle through the battery even when the AC is used if the battery is not dislodged---this is still a wear on the battery and cycles it through what ever life it had---they only have so many.

More than likely it is a bad battery---or used up: More than likely if it runs on AC without the battery installed or with the battery installed and the battery just tests out with little or no current then it's just an old battery.

There is more but you get the idea. I’d check for known issues with the unit as well.

Regardless, I think it safe to hazard a guess that the battery is just dead if the criteria above have been met.

Other than that, yep, you can try another battery. I ever had a similar problem with my .

If you find something different then I'd like to know.

I hope this helps.
