HP Pavilion 15 motherboard failure and charging cut-out, 8,100 TL replacement quote (Turkey)
A Turkish owner reports the Pavilion 15 stopping charging partway through a charge, then HP diagnosing a motherboard fault and quoting ~8,100 TL for replacement after warranty expired.
What to check. In Turkey, a charging cut-out on this model can be diagnosed as a motherboard fault costing thousands of lira out of warranty. Verify the fault with an independent repairer before paying HP's replacement quote, and keep the device in warranty as long as possible.
HP Pavilion 15-ef2729wm display flicker from video cable impinged at hinge
An owner of five units of the exact subject model reports four developing the same flicker/distortion, traced to the video cable being pinched where it routes around the hinge; freeing it worked only temporarily.
What to check. If you buy this model, expect a possible display flicker/line-distortion fault that recurs even after the cable is re-routed; it points to a design weakness at the hinge rather than a one-off unit. Check the screen during the return window.
HP Pavilion 14/15 series battery swelling, hinge cracks, screen flicker and overheating
A repair-shop aggregate lists the same four recurring Pavilion 14/15 faults — battery swelling, hinge crack, screen flicker, overheating — corroborating the owner reports above.
What to check. This corroborates the owner-level reports: expect battery swelling after a couple of years, hinge cracks, and the screen-flicker/loose-cable fault. These are repairable without a motherboard swap, but budget for them in years 2–3.
HP Pavilion 15-eg1xxx hard-reboots on sleep after Windows 11 26H2, BIOS F.26 incompatible
A Pavilion 15-eg1xxx owner reports hard-reboots (Kernel-Power 41) on entering Modern Standby after the Windows 11 26H2 update, tied to an incompatible BIOS revision.
What to check. After a Windows feature update, this series can hard-reboot when going to sleep until HP ships a compatible BIOS; the workaround is forcing S3 sleep via the registry. Keep BIOS and Windows updated, and expect possible sleep-related instability after major updates.
HP Pavilion 15 BSOD VIDEO_TDR_FAILURE with bad LCD, graphics driver fault
A Pavilion 15 (EH3000 variant) owner reports a failing LCD and a VIDEO_TDR_FAILURE blue screen, which the reply attributes to a graphics driver issue.
What to check. On a different Pavilion 15 variant, a VIDEO_TDR_FAILURE blue screen points to a graphics driver problem rather than hardware; update the AMD/Intel graphics driver first. This is lower-confidence because it is a different model from the subject.
These reports come from the pages linked under each item: owner forums, repair guides and workshops. They are not a diagnosis of any one unit, and a careful check of the one you are buying still applies.
