We have stack of 4 switches WS-C3750V2-48PS-S and some ports in 1 switch misbehaving .
User is connecting laptop on port and in arp table it is showing IP assigned under the assign vlan for port but that IP is not reachable . and when I am checking on user laptop IPconfig/all it is showing apipa IP.

Is the DHCP scope configured correctly? Does the switch assign IPs or a server? Can you post the output of "sh run"?

Yes , DHCP scope is configured correctly some interface under same vlan having no issues with same configuration .
We have IP helper address configured for vlan. thanks to confirm you need show run for impacted interfaces or whole switch .

you should have to try below commands on the laptop.
ipconfig /release
ipconfig /renew
have you tried that port shut/no shut.
