Hello ,

I'm going to buy a new lap but I'm currently confused between these two models:

Lenovo Ideapad Z510

- 4th Gen Intel® Core™ i5-4200M Processor (3M Cache, up to 3.10 GHz)
- 6GB DDR3 RAM
- 1TB HDD 5400 rpm
- DVD+/-RW drive
- 15.6" Backlit LED HD display (1366 x 768)
- NVIDIA GeForce GT 740M with 2 GB DDR3 dedicated
- 1.0MP fixed-focus (720p HD) webcam
- 6 cell battery
- No operating system
- WiFi - Bluetooth - Ethernet 10/100
- 1x HDMI, 1x USB 2.0, 2x USB 3.0

Dell Inspiron 15R 5537

- 4th Gen Intel® Core™ i5-4200U Processor (3M Cache, 1.6 GHz up to 2.60 GHz)
- 4GB DDR3L RAM
- 500GB 5400 rpm
- Tray-load DVD+/-RW
- 15.6 inch LED Backlit Display with Truelife and HD resolution (1366 x 768)
- AMD Radeon HD 8670M 2GB GDDR3
- Native HD 1.0MP webcam with digital microphone
- 6-cell Li-Ion
- No operating system
- WiFi - Bluetooth - Ethernet
- 1x HDMI, 2x USB 2.0, 2x USB 3.0

The Lenovo is better in specs and is 28$ higher in price

But I've heard that the battery and screen is poor, although some people says it's pretty good but it still confusing to me! In addition to that, i prefer DELL as a brand and i've tried it before it works pretty cool, and never tried Lenovo

Which one do you recommend ?

I'VE ALSO HEARD THAT THE LENOVO'S BATTERY IS NOT REPLACEABLE , IS THAT TRUE?

Regards ,,
