Dell Alienware 17 R5: Alienware 17 R5 won't turn on with new iFixit battery - single red flash

Mon, 11 May 2026 06:54:30 -0700

I recently purchased a replacement MG2YH battery from iFixit for my Alienware 17 R5. The laptop works perfectly fine with the old battery, but it will not turn on at all with the new one installed, even when the AC adapter is plugged in. When I first installed it, the power button flashed red once, but now there are no lights or response.

I have already tried:

1. A flea power release (holding the power button for 15-30 seconds with battery/AC disconnected).

2. An RTC/CMOS reset (disconnecting the coin-cell battery and holding the power button).

3. Attempting to boot with AC power only (which this model apparently does not support without a recognized battery).

Are there any specific BIOS settings or Alienware-specific "handshake" procedures I'm missing to get the motherboard to recognize this new battery, or is it likely a hardware defect in the new unit?

Any chance that the battery is in some kind of locked mode, or it's not working due to 0% charge?

when connected to wifi, the laptop cannot open pages like gmail and google for example. but when i connect it with a lan cable it works just fine. the laptop is basically useless without the lan cable (internet wise). everything else works spot on, this happened suddenly i did not upgrade any software or hardware. tried resetting to factory settings multiple times but still no luck any suggestions? thanks in advance
